oto — Claude Code plugin

The Claude Code companion for the Oto B2B automation toolkit: the hosted Oto MCP carries the tools, this plugin teaches Claude to drive them and installs the local oto CLI alongside.

Installing this plugin gives you:

• One universal oto skill — teaches Claude to discover and drive the toolkit (it does not duplicate per-tool manuals: the MCP catalogue is served by oto_list_my_tools, and the CLI is self-documenting via --help).
• An outbound guard — before any message leaves (email, WhatsApp, LinkedIn DM / invitation / post, Slack, Teams, Apollo or HelloStock send, also through oto_call), Claude Code asks you first, even in auto mode. Reads, drafts and dry runs pass freely; anything unreadable asks. See hooks/.
• /oto:setup — installs the oto CLI (pipx install "oto-cli[browser]") and connects the user's LinkedIn account.

The Oto MCP is not declared here on purpose — you add it once in claude.ai (so it's available in claude.ai and syncs into Claude Code), avoiding a duplicate connector. See the bootstrap below.

Surfaces

• MCP (hosted, added in claude.ai): company data, CRM, search, enrichment, Gmail, and LinkedIn — sourcing and outreach (linkedin_unipile_network op invite, linkedin_unipile_chat op send). The LinkedIn session is held by Unipile, our provider; nothing runs on your machine.
• CLI (local, via this plugin's skill + setup): the same toolkit as composable commands — for shell pipelines, and as a fallback when the MCP is unavailable.

Install

# distribution (public github marketplace)
claude plugin marketplace add otomata-tech/oto-plugin
# ou depuis un clone local (édition en place)
claude plugin marketplace add ./oto-plugin
claude plugin install oto@otomata-oto

Bootstrap for a new user

1. Add the Oto MCP in claude.ai — Settings → Connectors → Add custom connector: URL https://mcp.oto.cx/mcp, OAuth client ID 7p8h7cypq5mmpwmj2taao (PKCE, no secret). Authenticate (the popup also signs you up). It then also appears inside Claude Code.
2. Install this plugin (above) → Claude Code gets the oto skill + /oto:setup.
3. /oto:setup → installs the oto CLI.
4. Connect LinkedIn (only if you want LinkedIn) → human step, once: ask for a hosted connect URL (unipile_connect_start), open it, sign in there (2FA/captcha included). The link finalises by itself, server-side.

Steps 1 and 4 are the only irreducibly manual actions. LinkedIn — sourcing and outreach — runs through the hosted MCP, so it works from claude.ai just as well as from Claude Code.

Layout

.claude-plugin/{plugin,marketplace}.json   # manifest + local marketplace
skills/oto/SKILL.md                         # the universal skill
commands/setup.md                           # /oto:setup
hooks/{hooks.json,guard-outbound.mjs}       # the outbound guard (Node, no dependency)
tests/                                      # node --test "tests/*.test.mjs"

The tools live in the oto-cli package (PyPI) and the Oto MCP server — this plugin only bundles the skill (doctrine) + the CLI setup command.
