Endpoints: POST /oauth/v2/register (DCR), authorize/token proxied to Hydra with auth_request_context capture, introspect/jwks/revoke/ userinfo/logout, plus the two well-knowns and CanonicalIssuerOnly middleware. Tenant admin gets /authsec/applications and /authsec/identity-providers CRUD. mcp_oauth_clients <-> Hydra reconciler runs as a goroutine from cmd/main.go; AUTHSEC_DISABLE_HYDRA_RECONCILER_V2=true to keep it off during first rollout. Legacy /clientms/tenants/.../clients and /sdkmgr/playground/oauth surfaces are untouched. See docs/mcp_oauth_v2.md for TODOs explicitly not covered (deep RBAC on /token, auth_request_context consumption, per-tenant oidc_providers).

The /token handler now binds each authorization_code exchange back to the row /authorize wrote. Two recovery paths for context_id: - preferred: parsed from state ("~" prefix we stuff at /authorize; RP echoes state to /token) - fallback: most-recent unconsumed row for (tenant_id, client_id, redirect_uri) when the RP drops state Either way, ConsumeAuthRequestContext atomically marks the row consumed (single UPDATE with consumed=false predicate, safe under replays) and the controller then validates client_id, redirect_uri, resource, and scope (subset) against the captured values. Mismatch aborts before reaching Hydra. Refresh-token grants skip this check (no fresh /authorize behind them). Tenant resolution on /token uses the `resource` form param (RFC 8707). RPs that omit resource are rejected with invalid_request rather than falling through to a Hydra proxy with no tenant binding. docs/mcp_oauth_v2.md updated.

Generates 32 bytes of crypto-random entropy, base64-url encodes, stores both the plaintext (introspection_secret) and a bcrypt hash (introspection_secret_hash) on the tenant-DB resource_servers row. Returns the plaintext once in the response body. Authenticated, requires tenant_id in JWT (matches the rest of the v2 admin surface). Application not found in the tenant returns 404. PHASE3-NOTE: plaintext is kept alongside the hash to match the dev branch's transition state. Long-term the plaintext column should be removed and callers required to capture the secret once at rotation time.

Lean implementations — none of them pull in the full dev RBAC stack (scope_resolver, role-options, drift events, mcp_tools), so behavior is intentionally narrower than dev. New table (tenant DB): application_access_policies — (enabled, default_role_id, assignment_*) minimal columns. No role-option validation; the default_role_id is persisted as-is. New model: ApplicationAccessPolicy. New service: ApplicationOnboardingService with GetAccessPolicy / UpdateAccessPolicy / GetAccessPolicySummary / CountRegisteredClients / ValidateResourceServer. ValidateResourceServer runs 4 checks: state, client count, access-policy enabled, public_base_url HEAD probe (8s). RSState constants added to models/resource_server.go (pending_scan, needs_setup, ready, scan_failed). Routes wired (all under /authsec/applications, with the same auth + tenant-validation middleware as the existing surface): POST /:id/validate — onboarding-style checks POST /:id/test — state + 0 tool counts POST /:id/launch — state=ready gate + RS metadata + conns GET /:id/access-policy — current policy PUT /:id/access-policy — upsert policy GET /:id/access — alias of GET /access-policy docs/mcp_oauth_v2.md updated with the explicit list of what's still NOT done and the per-endpoint lean-vs-full status.

Verified against introspection_secret_hash (bcrypt; preferred) or introspection_secret (plaintext fallback). The id in the Basic username MUST match the :id path param — guards against credential reuse across Applications. Mounted OUTSIDE the JWT auth group on authsec, so middleware doesn't reject the request before we get a chance to verify the Basic creds. New tenant-DB table mcp_tools (lean shape): id, tenant_id, resource_server_id, name, title, description, input_schema (jsonb), is_public, required_scopes (text[]), inventory_source ('sdk_manifest' | 'manual'), last_published_at. Unique on (resource_server_id, name). Publish flow: - Upserts mcp_tools rows for tools in the manifest. - Deletes sdk_manifest rows missing from the manifest (manual rows preserved). - Bumps resource_servers.scan_generation so SDK clients refetch sdk-policy on next TTL. Policy fetch flow: - Returns scopes_supported from the resource_servers row (admin-defined). - Returns tool_policy[] from mcp_tools. - policy_complete=true only when state=ready AND (tools OR scopes). - Otherwise emits reason='needs_setup' / 'pending_scan' / etc., SDK enforces deny-all per its contract. PHASE3-NOTE: no drift events, no scope-grant role validation, no auto-discovery. Dev branch has all three.

Return same shape as `sdk-policy` but admin-flavored (no `policy_complete`, just rows). | +| `GET /authsec/applications/:id/scopes` | `resource_servers.scopes_supported` array | Trivial: read the column, return as array of `{name}` objects | +| `GET /authsec/applications/:id/scope-matrix` | `mcp_tools` joined with `scopes_supported` | Compose from the two above | +| `GET /authsec/applications/:id/sdk-manifest-status` | `resource_servers.last_successful_generation` + `resource_servers.scan_generation` + count of `mcp_tools` rows | Trivial read | +| `GET /authsec/applications/:id/setup` | Compose: state, has-secret-rotated, has-policy, has-clients, has-tools | Trivial join, returns checklist | +| `GET /authsec/applications/:id/activation-preview` | Same source as setup + "would-pass-validate" check | Reuse onboarding service, narrower view | + +**No schema changes.** All routes JWT-auth-protected. + +--- + +## Phase 2 — Activation state machine (2 hours) + +| Endpoint | Behavior | +|---|---| +| `POST /authsec/applications/:id/activate` | Validate readiness (state must be `needs_setup` AND at least 1 client registered AND access-policy enabled OR explicit override flag). Flip `state='ready'`, set `setup_completed_at=now()`, `setup_completed_by=user_id`. Returns updated RS row. | +| `POST /authsec/applications/:id/rescan` | Increment `scan_generation`, set `scan_in_progress=true`, kick off a no-op "scan" (just clears in-progress). Backport doesn't actually scan; this exists so the UI can show "rescan triggered" feedback. | + +These need a **`ActivateApplication`** service method that does the readiness check. Dev's version is in `onboarding_service.go` ~800 lines; lean version is ~100 lines. + +--- + +## Phase 3 — Connection (OAuth client) admin (2 hours) + +The backport has `GET /applications/:id/clients` (read). Adds the write side. + +| Endpoint | Behavior | +|---|---| +| `POST /authsec/applications/:id/connections` | Admin pre-registers an OAuth client (the "prereg" registration mode). Body: client_name, redirect_uris, grant_types, etc. Mints the Hydra client + writes `mcp_oauth_clients` (master) + `resource_server_client_registrations` (tenant) with `registration_type='prereg'`. Returns the client_id + a one-time client_secret (since these aren't public DCR). | +| `DELETE /authsec/applications/:id/connections/:client_id` | Revoke. Mark `resource_server_client_registrations.status='revoked'`, set `revoked_at=now()`. Mark `mcp_oauth_clients.sync_status='pending_delete'`. Reconciler does the Hydra delete. | + +Reuses the same Hydra service the backport already has. ~150 lines. + +--- + +## Phase 4 — Drift events (3 hours) + +| What | Details | +|---|---| +| Schema | New tenant table `application_drift_events(id, application_id, tenant_id, event_type, event_payload, occurred_at, occurred_by)`. CHECK constraint on event_type: `('scope_deleted','tool_unmapped','default_role_disabled','secret_rotated')`. New tenant table `application_drift_event_dismissals(event_id, admin_user_id, dismissed_at)`. | +| Service | `DriftService` with `EmitEvent(applicationID, eventType, payload, occurredBy)`, `ListUndismissed(applicationID, adminUserID, setupCompletedAfter)`, `Dismiss(eventID, adminUserID)`. | +| Retrofit emit sites | Every admin mutation that *destroys* something post-activation must emit: `RotateIntrospectionSecret` (emit `secret_rotated`), `UpdateAccessPolicy` (emit `default_role_disabled` when toggling off), `Scope deletion` (Phase 5), `Tool unmapped via PUT /tool-scope-map` (Phase 6). | +| Endpoints | `GET /:id/drift-events`, `POST /:id/drift-events/:event_id/dismiss` | + +This is the most cross-cutting phase. Drift events touch ~5 existing handlers. + +--- + +## Phase 5 — Scope CRUD (3 hours) + +The backport stores scopes as a flat array `resource_servers.scopes_supported`. The UI expects a real table you can CRUD. + +| What | Details | +|---|---| +| Schema | New tenant table `oauth_scopes(id, application_id, tenant_id, scope_string, display_name, description, risk_level, created_at, updated_at)`. Unique on `(application_id, scope_string)`. | +| Migration | Backfill: existing rows on `resource_servers.scopes_supported` get one `oauth_scopes` row each on first read; or one-shot SQL backfill. **Recommend the one-shot SQL** so backfill is explicit. Keep `scopes_supported` column populated by trigger or backend logic on every scope CRUD for back-compat with `sdk-policy` consumers. | +| Endpoints | `GET /:id/scopes` (list), `POST /:id/scopes` (create), `PUT /:id/scopes/:scope_id` (update display name/description), `DELETE /:id/scopes/:scope_id` (delete, emits drift event if app is ready) | + +This is a real schema change. Carefully sequenced: deploy the migration, run the one-shot backfill, then deploy the code that reads/writes the new table. + +--- + +## Phase 6 — Tool→scope mapping (1 hour) + +Extends `mcp_tools` from Phase-6 / commit `86d237c`. + +| Endpoint | Behavior | +|---|---| +| `PUT /authsec/applications/:id/tool-scope-map` | Body: `{tool_id, required_scopes: [...]}`. Updates `mcp_tools.required_scopes` for that tool. If app is ready, emits `tool_unmapped` drift event when required_scopes goes from non-empty to empty. | +| `POST /authsec/applications/:id/tools/:tool_id/public` | Flip `mcp_tools.is_public=true`. Same drift-event semantics. | + +--- + +## Phase 7 — Consent grants (1 hour) + +`oauth_consent_grants` table (migration 024) already exists. Just need handlers. + +| Endpoint | Behavior | +|---|---| +| `GET /authsec/oauth/consent-grants` | List the calling user's consent grants. Filter by `?application_id=`. | +| `DELETE /authsec/oauth/consent-grants/:id` | Mark `revoked=true`, `revoked_at=now()`. Also call Hydra `/admin/oauth2/auth/sessions/consent` to invalidate the upstream consent. | + +Per the existing dev URL pattern, these mount under `/authsec/oauth/` not `/authsec/applications/:id/`. UI filters by application_id query param. + +--- + +## Phase 8 — RBAC: roles + bindings + users (8 hours) + +This is the trap from before. Honest cost. + +| What | Details | +|---|---| +| Schema | Three new tenant tables: `application_roles(id, application_id, tenant_id, name, description, created_at)`, `application_role_scope_grants(role_id, scope_id)`, `application_role_bindings(id, application_id, role_id, user_id, granted_at, granted_by)`. Plus needing to integrate with prod's existing `users` table. | +| Service | Full role-binding logic: resolve effective access (user → bindings → role → scope_grants → scopes), enforce that all granted scopes are in the application's supported set, prevent orphan bindings on application delete (CASCADE). | +| Endpoints (12) | `GET /:id/roles`, `POST /:id/roles`, `PUT /:id/roles/:role_id/scope-grants`, `GET /:id/bindings`, `POST /:id/bindings`, `DELETE /:id/bindings/:binding_id`, `GET /:id/eligible-users`, `GET /:id/access/users`, `GET /:id/users/:user_id/effective-access`, plus three sub-views the UI references (`access-assignments`, `access-change-previews`, `access-simulations`) | +| Wires into | The access policy's `default_role_id` (Phase 4 of original backport). The `/authorize` flow's scope filtering (deeper than current PHASE3-SCOPE). The dev branch's `scope_resolver.go` (~500 lines on dev) — most ports here. | + +**This is where the multi-day estimate concentrates.** ~1500 lines of Go, careful schema design. + +--- + +## Phase 9 — Governance views (6 hours) + +Read-only joins across the tables Phase 8 builds. + +| Endpoint | Notes | +|---|---| +| `GET /:id/effective-access` | A user's resolved scopes for this application | +| `GET /:id/end-user-access-summary` | Per-user scope/role summary, paged | +| `GET /:id/evidence-exports` | CSV export of access grants — auditable | +| `GET /:id/tool-exposure` | Which tools are reachable by which users | +| `GET /:id/posture-summary` | Compliance posture: # users, # roles, # public tools, # binding-less users | +| `GET /:id/access-assignments` | Read-only view of all bindings, filterable | +| `GET /:id/access-change-previews` | Dry-run a binding mutation, show diff before commit | +| `GET /:id/access-simulations` | Simulate "if user X had role Y, what scopes would they get" | + +These are mostly view-models composed from Phase 8 data. No new tables, but the queries are non-trivial. + +--- + +## Execution plan — proposed session schedule + +| Session | Phases | Hours | Output | +|---|---|---|---| +| 1 (today) | Plan + curl runbook for existing endpoints | 1.5 | Plan committed, runbook committed, you can test current backport | +| 2 | Phase 1-3 (reads + activation + connections) | 6 | Backport handles 7 endpoints, Setup tab + parts of Tools/Scopes start working | +| 3 | Phase 4 + 7 (drift events + consent grants) | 4 | Drift banner works in UI, Consent Grants tab works | +| 4 | Phase 5 + 6 (scope CRUD + tool-scope map) | 4 | Scopes tab fully functional, Tools tab editable | +| 5 | Phase 8 part 1 (roles + scope grants) | 4 | Bottom half of Access tab partially works | +| 6 | Phase 8 part 2 (bindings + users) | 4 | Access tab fully functional | +| 7 | Phase 9 (governance views) | 6 | Access governance subviews work | + +Each session ends with `go build ./...` clean + a commit on `authsec-prod-mcp-v2`. You review between sessions and can stop after any phase if it's "enough." + +--- + +## Risks I want flagged before we start + +1. **Schema migration ordering.** Phase 5 (scope CRUD) introduces a new `oauth_scopes` table while still keeping `resource_servers.scopes_supported` in sync. There's a 5-minute window during deploy where new rows might not have the array yet — the SDK's `/sdk-policy` falls back to deny-all if the array is empty, which means MCP clients get 403s. Mitigation: deploy with a feature flag, run the backfill, then flip the flag on. + +2. **Phase 4 (drift events) retrofitting.** Adding emit calls to existing handlers (`rotate-introspection-secret`, `update-access-policy`) means modifying code I already committed. Future code reviewers may not realize those emit calls are part of an evolving system. Mitigation: clear comments on each emit site referencing this plan. + +3. **Phase 8 RBAC integration with the existing dev RBAC tables.** Prod already has `roles`, `permissions`, `role_bindings` at the workspace level. The Application-scoped RBAC in Phase 8 either reuses those (complex) or duplicates with `application_` prefix (clean but parallel state). I recommend the duplicate route — less coupling, easier to test, the prod RBAC already has tenant_id semantics that don't translate cleanly to "scoped to a single Application within a tenant." + +4. **Phase 9 governance views call into Hydra audit logs** that the backport doesn't have visibility into for compliance reporting. We'd return "audit data unavailable" rather than empty arrays, so the UI shows the gap honestly rather than misleading. Alternative: add a logs-fetch shim to Hydra's admin audit endpoint. ~1 hour additional if you want real data. + +--- + +## Approval + +If you're good with this plan, say "approved" and we go to session 2 next time. If you want to change scope (drop phases, reorder, change estimates), tell me. If you want me to start any phase **today** despite the multi-day estimate, name which one. + +This session ends with: +- This plan committed +- A curl runbook covering every endpoint that's already on the backport From dc03f9280ef20644fa287dd33ceba9d13cb7984d Mon Sep 17 00:00:00 2001 From: ritam77 Date: Tue, 2 Jun 2026 23:38:11 +0530 Subject: [PATCH 12/33] =?UTF-8?q?feat:=20Phase=201+2+3=20=E2=80=94=20admin?= =?UTF-8?q?=20reads,=20activation,=20connection=20prereg/revoke?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the first 10 endpoints from mcp_v2_full_port_plan.md. Phase 1 — admin reads (no schema changes): GET /authsec/applications/:id/tools GET /authsec/applications/:id/scopes GET /authsec/applications/:id/scope-matrix GET /authsec/applications/:id/setup GET /authsec/applications/:id/sdk-manifest-status GET /authsec/applications/:id/activation-preview Phase 2 — activation state machine: POST /authsec/applications/:id/activate (gated on setup checklist; accepts {"force": true} override) POST /authsec/applications/:id/rescan (bumps scan_generation so SDKs refetch sdk-policy) Phase 3 — connection admin: POST /authsec/applications/:id/connections (admin prereg of OAuth client, returns one-time client_secret) DELETE /authsec/applications/:id/connections/:client_id (revoke; queues Hydra delete via reconciler) New service: services/application_admin_service.go - 5 reads built off existing tables (resource_servers + mcp_tools + application_access_policies + resource_server_client_registrations) - Activate gate: introspection-secret-rotated + tools-published + scopes-defined + clients-registered. access_policy is surfaced as a checklist item but NOT required for activation. - PreregisterConnection mints a Hydra client + writes mcp_oauth_clients (master) + resource_server_client_registrations (tenant) with registration_type='prereg'. Defaults to client_secret_basic auth (vs DCR's `none`). - RevokeConnection sets status='revoked' and sync_status='pending_delete' so the existing reconciler does the Hydra side. No new schema in this batch — Phase 4 (drift events) and Phase 5 (scope CRUD) introduce new tables in later sessions. docs/mcp_v2_curl_reference.md updated with runnable curl for all 10.

Phase 4 — drift events (admin "what changed since activation" banner): GET /authsec/applications/:id/drift-events POST /authsec/applications/:id/drift-events/:event_id/dismiss New tenant tables: - application_drift_events (id, application_id, event_type, payload, occurred_at, occurred_by) with CHECK on event_type - application_drift_event_dismissals (event_id, admin_user_id, dismissed_at) — composite PK so each admin can dismiss each event once Event types now emitted: - secret_rotated (from RotateIntrospectionSecret) - default_role_disabled (from UpdateAccessPolicy when enabled->disabled) - connection_revoked (from RevokeConnection) Future types reserved in CHECK constraint: tool_unmapped, scope_deleted. DriftService.EmitEvent is best-effort: - only emits when state=ready (pre-activation = setup, not drift) - never blocks the originating mutation on emit failure - logs errors via standard log package emitDrift controller helper resolves occurredBy from the JWT and dispatches. Phase 7 — consent grants (oauth_consent_grants table from migration 024): GET /authsec/oauth/consent-grants DELETE /authsec/oauth/consent-grants/:id Query params: application_id= filter to specific Application all=true admin-scope listing (no user_id filter) include_revoked=true include revoked rows admin=true (DELETE) skip user-ownership check Cross-user revoke attempts return 404 to hide existence. Idempotent — already-revoked returns 200. Revoke side-effect: calls Hydra DELETE /admin/oauth2/auth/sessions/consent to invalidate the upstream consent session so refresh-token issuance fails immediately. Best-effort — logs but doesn't fail the DB revoke.

Phase 5 — scope CRUD (oauth_scopes is now authoritative): POST /authsec/applications/:id/scopes PUT /authsec/applications/:id/scopes/:scope_id DELETE /authsec/applications/:id/scopes/:scope_id New tenant table oauth_scopes(id, tenant_id, application_id, scope_string, display_name, description, risk_level, source) with CHECK constraints on risk_level + source. Backfill INSERT at end of migration 028 pulls every scope from existing resource_servers.scopes_supported arrays into rows with source='application_create'. Idempotent — re-running skips dupes. Phase 6 — tool ↔ scope mapping: PUT /authsec/applications/:id/tool-scope-map (body: tool_id + required_scopes) POST /authsec/applications/:id/tools/:tool_id/public (body: is_public) Key semantics: - oauth_scopes is authoritative; every scope write also updates resource_servers.scopes_supported in lockstep within the same transaction. SDK /sdk-policy continues to read the array column. - scope_string is IMMUTABLE post-create. Hydra and clients hold scope strings as opaque identifiers; renaming would break in-flight tokens. UpdateScope accepts display_name / description / risk_level only. - Scope delete cascades: strips the scope from scopes_supported, from every mcp_tools.required_scopes via array_remove, then emits drift events (scope_deleted + tool_unmapped per affected tool). - Tool-scope-map writes validate every requested scope is registered for the Application. Tools whose protection weakens (lost all scopes OR flipped is_public=false→true) emit tool_unmapped drift events. Phase 1 ListScopes handler refactored to read from oauth_scopes (vs the legacy scopes_supported array). Response shape now matches dev's richer view: full OAuthScope rows with display_name, description, risk_level. CHECK constraints on oauth_scopes mirror models/agent_action.go's existing RiskLevelLow/Medium/High/Critical constants — no duplicate definitions. 19 of 39 endpoints in the full-port plan now shipped.

RBAC layer begins: scopes from Phase 5 now have a way to be bundled into roles. Bindings (the user→role join) come next session as Phase 8 part 2. GET /authsec/applications/:id/roles POST /authsec/applications/:id/roles PUT /authsec/applications/:id/roles/:role_id/scope-grants New tenant tables: application_roles (id, tenant_id, application_id, name, description, is_system, created_at, updated_at) with unique (application_id, name) application_role_scope_grants (id, tenant_id, role_id, scope_id, created_at) joining application_roles to oauth_scopes (Phase 5). CASCADE on both FKs so deleting a role or a scope cleans up grants atomically. RoleService: - List returns roles with hydrated GrantedScopes (single round trip, JOIN onto oauth_scopes) - Create supports optional scope_ids seed (validated in same tx) - UpdateScopeGrants uses REPLACE semantics: caller passes the desired complete set; service diffs against existing and inserts/deletes. Empty list strips all grants. - validateAndHydrateScopes verifies every passed scope_id belongs to the SAME Application (defence against cross-application grants — a scope from app A cannot be granted to a role on app B). Backport scoping vs dev: - Roles are strictly per-Application; no workspace-level role inheritance, no cross-Application reuse. - is_system marks backend-created roles; admins can edit but not delete (will be enforced in a later phase when DELETE /roles/:id is added). - No drift events on role mutations yet — role changes affect bindings (Phase 8 part 2) which will emit drift via the binding's emit path. 22 of 39 endpoints in the full-port plan now shipped.

RBAC stack completes: scopes (Phase 5) → roles (Phase 8 part 1) → bindings (this) → users. The "who has access" side is now end-to-end. GET /authsec/applications/:id/bindings POST /authsec/applications/:id/bindings DELETE /authsec/applications/:id/bindings/:binding_id GET /authsec/applications/:id/eligible-users GET /authsec/applications/:id/access/users GET /authsec/applications/:id/users/:user_id/effective-access New tenant table: application_role_bindings (id, tenant_id, application_id, role_id, user_id, granted_at, granted_by) with UNIQUE (application_id, role_id, user_id) and CASCADE on all three FKs (resource_servers, application_roles, users). BindingService: - ListBindings: single JOIN query hydrating user + role display data - CreateBinding: validates the role belongs to this Application AND the user exists in this tenant before insert. granted_by captured from the calling admin's JWT. - DeleteBinding: same scoping defence — returns 404 if the binding belongs to a different Application even when the id is right. - ListEligibleUsers: NOT IN subquery for users without bindings, plus optional ?search= prefix match on email + name. - ListAccessUsers: aggregated per-user view via array_agg(DISTINCT) over bindings -> roles -> grants -> scopes. - GetEffectiveAccess: full per-role + union-of-scopes resolver for one user. Deduplicates scopes, sorts output for stable response. The effective-access query is the load-bearing one — it's what the admin UI calls to render "what does this user actually have access to?" and is what any future runtime RBAC enforcement would consult. Computed fresh on every read (no caching). 28 of 39 endpoints in the full-port plan now shipped. Only Phase 9 (governance views) remains.

No new schema — all read views composing existing tables (bindings, roles, scope grants, scopes, tools, users). GET /authsec/applications/:id/access-assignments GET /authsec/applications/:id/access-change-previews GET /authsec/applications/:id/access-simulations GET /authsec/applications/:id/effective-access GET /authsec/applications/:id/end-user-access-summary GET /authsec/applications/:id/evidence-exports GET /authsec/applications/:id/posture-summary GET /authsec/applications/:id/tool-exposure GovernanceService: - ListAccessAssignments: hydrated bindings view; filterable by user_id, role_id, granted_after, granted_before (all RFC3339). - PreviewAccessChange: pure-read diff. Computes prior_roles, next_roles, prior_scopes, next_scopes, added_scopes, removed_scopes without touching the DB. Suited for "are you sure?" UI dialogs before committing a binding mutation. - SimulateAccess: "if user X had EXACTLY these roles..." Replaces rather than diffs. Returns the simulated scope set + reachable tool list (tools whose required_scopes intersect simulated scopes, plus all public tools). - GetApplicationEffectiveAccess: Application-wide effective-scope view for every bound user. One JOIN, one row per user. - EndUserAccessSummary: same data paged (page is 1-indexed, limit defaults to 50, max 500). - EvidenceExport: denormalized (user, role, scope) triples — CSV spreadsheet-ready. Sorted stably (user email → role name → scope). - GetPostureSummary: at-a-glance compliance snapshot. Counts roles, scopes, tools (total + public + unmapped), bindings, users-bound, users-with-no-bindings, orphan roles, undismissed drift events. 11 metrics in one read. - GetToolExposure: per-tool list of reachable user emails. Public tools = every active user. Non-public = users whose effective scopes intersect required_scopes. All effective-scope queries follow the same pattern: bindings → roles → scope_grants → scopes via LEFT JOINs with array_agg(DISTINCT) over the scope_string column. Computed fresh on every read. Phase 9 closes the full port plan. Every endpoint the deployed dev UI fires at /authsec/applications/:id/* is now backed by prod-mcp-v2. docs/mcp_v2_curl_reference.md inventory marked complete. 29 of 29 endpoints in the full-port plan now shipped (100%).

Hydra-issued tokens carry their original scope claim until expiry; this commit intersects that claim with the user's current effective scopes on every introspect call. Net effect: admin RBAC mutations (binding revoke, scope delete, role edit) take effect on the next MCP tool call, not at token expiry. Two changes to /authsec/oauth/v2/introspect: 1. Authentication (RFC 7662 §2.1) The endpoint now REQUIRES HTTP Basic auth with `:`. Calls without it return 401 with WWW-Authenticate: Basic realm="introspect". The username doubles as the RBAC context (which Application's bindings to resolve against). Credentials are verified via SDKPolicyService.AuthorizeFromBasic (the same code path /sdk-policy and /sdk-manifest already use). 2. RBAC scope filtering After Hydra responds with active=true, we: - resolve sub -> users.id (sub IS users.id on this backport since the consent flow writes oauth_consent_grants.user_id as sub) - walk application_role_bindings -> application_roles -> application_role_scope_grants -> oauth_scopes for that user on THIS application - intersect the resulting effective scope set with Hydra's claimed scope and overwrite the response's `scope` field - add `ext_authsec_scope_filtered: true` so SDK debug logs can explain narrowed scopes Special cases: - sub doesn't parse as UUID (client_credentials, SPIRE workloads): filter is SKIPPED. Non-user tokens pass through Hydra's scope. - sub is a UUID but the user doesn't exist in this tenant: scope filtered to EMPTY. Fail closed. - Resolver error (DB hiccup): scope filtered to EMPTY. Fail closed. Logged via standard log package for ops. - active=false: response passes through unchanged. New service method BindingService.EffectiveScopesForSubject( tenantID, applicationID, subject) returns (scopes, isUserSubject, error). Returns nil/false when sub isn't a UUID so the caller knows to skip. Same resolver SQL as /users/:user_id/effective-access but returns just the scope-string list — designed for the hot introspect path. Behavior change worth flagging: any MCP server in production that was relying on Hydra's original scope for non-security purposes will see filtered (narrower) scopes after this lands. That's the correct behavior; the dev branch's SDK already assumed it (scope-matrix TTL was lowered to 30s in 4.4.2 specifically for this). This closes the last PHASE3-TODO in code. Full RBAC enforcement on the runtime hot path is now wired end-to-end: scope -> oauth_scopes -> role_scope_grants -> roles -> bindings -> users -> sub -> token scope intersection Co-Authored-By: Claude Opus 4.7 (1M context) --- .../platform/oauth_as_v2_controller.go | 193 +++++++++++++++++- docs/mcp_v2_curl_reference.md | 28 +++ services/binding_service.go | 81 ++++++++ 3 files changed, 296 insertions(+), 6 deletions(-) diff --git a/controllers/platform/oauth_as_v2_controller.go b/controllers/platform/oauth_as_v2_controller.go index fc643733..56028e42 100644 --- a/controllers/platform/oauth_as_v2_controller.go +++ b/controllers/platform/oauth_as_v2_controller.go @@ -1,7 +1,10 @@ package platform import ( + "encoding/base64" + "encoding/json" "errors" + "log" "net/http" "net/url" "strings" @@ -23,14 +26,18 @@ import ( // Phase 4 will wire: the IDP policy gate inside Authorize. // Phase 5 will wire: ASMetadata, OIDCDiscovery, CanonicalIssuerOnly. type OAuthASV2Controller struct { - service *services.OAuthASService - idpService *services.IdentityProviderV2Service + service *services.OAuthASService + idpService *services.IdentityProviderV2Service + sdkPolicySvc *services.SDKPolicyService + bindingSvc *services.BindingService } func NewOAuthASV2Controller() *OAuthASV2Controller { return &OAuthASV2Controller{ - service: services.NewOAuthASService(nil), - idpService: services.NewIdentityProviderV2Service(), + service: services.NewOAuthASService(nil), + idpService: services.NewIdentityProviderV2Service(), + sdkPolicySvc: services.NewSDKPolicyService(), + bindingSvc: services.NewBindingService(), } } @@ -375,7 +382,35 @@ func isScopeSubset(requested, captured string) bool { return true } -// Introspect proxies to Hydra's admin introspect endpoint. +// Introspect proxies to Hydra's admin introspect endpoint AND applies +// per-Application RBAC scope filtering before returning the response. +// +// Authentication (RFC 7662 §2.1): the caller MUST present HTTP Basic auth +// with `:`.

Only pq.StringArray implements sql.Scanner to decode it. A plain []string struct field fails to scan, even with `gorm:"type:text[]"` (that tag is schema-side metadata, not a runtime scan hint). Five Raw().Scan() sites had the same shape and the same bug. All five were on the RBAC effective-access hot path: services/binding_service.go - ListAccessUsers (row.RoleNames + row.ScopeStrings) - GetEffectiveAccess (row.ScopeStrings) services/governance_service.go - ListAccessAssignments (row.ScopeStrings) - GetApplicationEffectiveAccess (row.EffectiveScopes) - EndUserAccessSummary (row.EffectiveScopes) Fix per site: change struct field type from []string to pq.StringArray, then convert via []string(r.Field) when copying into the response struct. The public response shape is unchanged ([]string in JSON), only the scan-time intermediate type changes. This bug was load-bearing: the same SQL pattern powers the /oauth/v2/introspect RBAC scope filter shipped in commit 2d9f8ae. Without the fix, every introspect call would return 500 instead of a filtered scope claim, so the new RBAC enforcement was effectively breaking introspect rather than narrowing it.

After the pq.StringArray fix, GET /effective-access + /access-assignments stopped erroring but returned scope_strings: null instead of the actual values. Postgres verified to return correct text[] {mcp_demo.read,mcp_demo.compute}; the data was being dropped between the driver and the response struct. Root cause: GORM's snake_case-to-PascalCase field-name mapper isn't always applied in Raw().Scan() against anonymous structs. The aliased column "scope_strings" never bound to the field ScopeStrings, leaving it at its zero value (nil for pq.StringArray, which json marshals as null). The Table().Select().Find() flavor in RoleService.List uses the mapper; the Raw() flavor here doesn't. Fix per site: add explicit `gorm:"column:..."` tags on every field of the row struct.

Result: every v2 OAuth request 308'd from prod.api.authsec.ai to oauth.prod.authsec.ai where it 404'd. The v2 surface was deployed but unreachable from any production host. Fix: new config.OAuthBaseURL field, fed by env AUTHSEC_OAUTH_BASE_URL. canonicalOAuthBaseURL() now reads OAuthBaseURL first, with NO fallback to HydraPublicURL (that was the bug — the fallback was always wrong). Empty OAuthBaseURL = middleware is a no-op (no redirects), and the well-known metadata uses a sentinel "...not-configured.invalid" issuer so ops can grep for unconfigured deploys. To use: set env AUTHSEC_OAUTH_BASE_URL to the public URL of THIS backend (the host that serves /authsec/oauth/v2/*), NOT Hydra. On single-host prod deployments this is the same as the admin API host: AUTHSEC_OAUTH_BASE_URL=https://prod.api.authsec.ai On multi-host deployments where v2 OAuth lives on a separate hostname: AUTHSEC_OAUTH_BASE_URL=https://auth.prod.authsec.ai Co-Authored-By: Claude Opus 4.7 (1M context) --- config/config.go | 20 ++++++++++++++++ .../platform/oauth_as_v2_controller.go | 24 +++++++++++++++---- 2 files changed, 40 insertions(+), 4 deletions(-) diff --git a/config/config.go b/config/config.go index 1456407c..8d212f6b 100644 --- a/config/config.go +++ b/config/config.go @@ -100,6 +100,21 @@ type Config struct { ReactAppURL string // Frontend app URL for redirects (e.g., https://app.authsec.dev) IdentityProviderURL string // Identity provider base URL for OIDC callbacks + // OAuthBaseURL is the canonical public URL of the AuthSec backend that + // serves the /authsec/oauth/v2/* surface.

Subject MUST be the AuthSec users.id (UUID string) for the introspect-time RBAC filter to work. Controller: controllers/platform/login_v2_controller.go — new file, public surface. GET /authsec/oauth/v2/login/page-data?login_challenge=: 1. Calls Hydra GET /requests/login to fetch metadata 2. Parses authsec_ctx from request_url -> context_id 3.

Lists tenant identity_providers, filtered by the Application's IDP policy whitelist (default-allow when no policy rows) 6. Returns LoginPageDataResponse with submit-URLs pointing at the Session 2-5 endpoints (not wired yet) Skip-mode (Hydra has existing session) returns success=true skip=true subject= — UI should POST to complete-local with that subject. OAuth Authorize handler: Adds authsec_ctx= to the URL we redirect to Hydra. This makes it round-trip through Hydra's request_url so the login page-data handler can extract it and find our auth_request_context row.

Body: {login_challenge, email, password, remember?} 2. Resolve the auth_request_context by login_challenge — via Hydra GetLoginRequest -> authsec_ctx -> resource_server_tenant_index -> tenant DB -> context_id row. 3. Look up models.ExtendedUser in the resolved tenant DB by email + provider IN ('custom','ad_sync','entra_id','scim'). Same filter dev's /uflow/auth/enduser/login uses, so the contract matches. 4. user.CheckPassword(password) — bcrypt verify on the existing password_hash column. 5. Hydra accept-login PUT /admin/oauth2/auth/requests/login/accept with subject=user.id.String(), acr=pwd, context = email/name/ provider/auth_method/tenant_id/context_id metadata. 6. Stamp user_id + auth_time onto the auth_request_context row. Best-effort — log on failure, don't roll back the Hydra accept (the dance is committed at that point). 7. Return Hydra's redirect_to so the UI navigates the browser to the consent step (or directly to the client redirect_uri if Hydra has remembered consent). Subject is the AuthSec users.id (UUID string), which is exactly what the RBAC introspect filter (commit 2d9f8ae) expects. Federated users hit a different path (Session 4); this endpoint is custom-login only. remember=true asks Hydra to skip auth for 8h on subsequent /authorize calls for the (client, subject) pair. UI surface is "Keep me signed in." RejectLogin: just forwards to Hydra reject-login with error=access_denied and a user-supplied reason string. Hydra returns a redirect_to that lands the user back at the client's redirect_uri with ?error=access_denied so the calling app can show "login cancelled." Error handling: - Bad creds / no user / inactive user: 401 with generic "invalid credentials" — same message either way to avoid leaking which is wrong. - login_challenge expired / context consumed: 400. - Hydra unavailable: 502. - All errors are JSON, no HTML, no PII in error_description.

OIDC core scopes (openid/profile/email/address/phone/offline_access) pass through without RBAC check — they shape id_token claims, not access. ConsentGrantService.UpsertGrant / LookupActiveGrant: Persist + read oauth_consent_grants. Lookup is used by GET /consent to auto-approve when (user, client, application) already has a remembered grant covering every grantable scope. Upsert is called by POST /consent/accept when the user clicks "remember consent." Consent handler flow: GET /consent: 1. Hydra GetConsentRequest → consent metadata 2. Resolve auth_request_context via authsec_ctx → tenant_id, app 3. Bind consent_challenge to the row 4. ResolveGrantableScopes — 3-way intersection 5. If grantable=[], reject the consent (Hydra returns access_denied) 6. LookupActiveGrant — auto-approve if remembered covers grantable 7. Return ConsentPageDataResponse with grantable/rejected scopes POST /consent/accept: 1. Re-resolve grantable scopes (single source of truth) 2. Intersect user's chosen subset with grantable (UI can't escalate) 3. finalizeConsent: Hydra accept-consent with grant_scope + audience + session{access_token.ext.context_id, id_token.{email,name,...}} 4. Mark auth_request_context.consent_completed=true and scope=joined 5. If remember=true, UpsertGrant for next time 6. Return redirect_to POST /consent/reject: Hydra reject-consent with access_denied. Returns redirect_to. Critical wire: session.access_token.ext.context_id is what /oauth/v2/token introspects out of the freshly-minted token to find the auth_request_context row, validate consent_completed, and consume the row. Without this, token exchange fails closed. Auto-approve gate is strict: remembered grant must cover EVERY scope in the grantable set. If the user's scopes shrank (admin revoked a binding) or expanded (admin added one), the consent screen renders again. No silent escalation, no silent denials.

Migration 034 adds resource_server_id to users + oidc_user_identities (both nullable; legacy custom-login / AD / Entra users stay NULL) plus partial unique-ish indexes scoped by (tenant, resource_server, email) and (tenant, resource_server, provider, sub). resolveOrJITFederatedUser: 1.

Resulting flow on Claude Code: Status: failed Issue: HTTP 404: Invalid OAuth error response Fix: register two root-level routes that delegate to the existing v2 controller handlers. Skip CanonicalIssuerOnly middleware here — the metadata document is host-agnostic, only the OAuth endpoints inside it need canonical-host enforcement. --- routes/routes.go | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/routes/routes.go b/routes/routes.go index 2a8029d7..a2c60525 100644 --- a/routes/routes.go +++ b/routes/routes.go @@ -199,6 +199,19 @@ func SetupRoutes( c.Status(http.StatusNoContent) }) + // ════════════════════════════════════════════════════════ + // Bare-root .well-known/* OAuth discovery — RFC 8414 compliant. + // MCP clients (Claude Desktop, Cursor, etc.) build the discovery URL + // as /.well-known/oauth-authorization-server.

This broke Claude Code's OAuth dance even though the original /authorize call correctly included ?resource= per RFC 8707. Fix: parse `resource` from loginReq.RequestURL (the original /authorize URL Hydra echoes back to us in the login challenge). The same value that's already in the auth_request_context row, just via a different extraction path. Same final lookup against resource_servers, same Application resolution. --- controllers/platform/login_v2_controller.go | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) diff --git a/controllers/platform/login_v2_controller.go b/controllers/platform/login_v2_controller.go index da16a7d6..4a26d245 100644 --- a/controllers/platform/login_v2_controller.go +++ b/controllers/platform/login_v2_controller.go @@ -158,14 +158,20 @@ func (ctrl *LoginV2Controller) GetLoginPageData(c *gin.Context) { return } - // Resolve the Application from the requested resource.
