Choose the right Docsy integration

I want to…	Use
Connect ChatGPT, Claude Code, Codex, Cursor or another AI client	Docsy AI / MCP Plugin → — installation guides, supported-client manifests and versioned ZIP packages
Open Docsy in ChatGPT	Publisher-provided ChatGPT plugin link — availability varies; a direct link does not prove official store approval
Search documentation in a terminal	Docsy CLI — published on npm
Call Docsy from TypeScript or JavaScript	Docsy SDK — published on npm
Use Gemini CLI	Gemini CLI extension — tagged public GitHub integration
Use MCP directly	Connect the hosted endpoint https://docsy.remcp.site/mcp/registry and authorize your Docsy account

The AI / MCP Plugin repository is separate from this SDK / CLI repository. Both connect to the same remote Docsy documentation service. Neither includes the private crawler, index database or production backend.

MCP tools for AI assistants

Docsy's companion AI / MCP Plugin offers five read-only tools: resolve-library-id, list-library-versions, query-docs, search, and fetch. They retrieve versioned public documentation and publisher source links through https://docsy.remcp.site/mcp/registry with OAuth 2.1. This repository ships the separate SDK and CLI; the public plugin repository is the installation and tool reference for AI clients.

Quick start

Requires Node.js 22 or later.

Terminal / CLI

npm install --global @remcp/docsy-cli

docsy --help
docsy library react
docsy docs /reactjs/react.dev "useEffect cleanup"
docsy search "Next.js caching" --library next.js

Run once without a global installation:

npx --yes --package=@remcp/docsy-cli docsy library react

TypeScript SDK

npm install @remcp/docsy-sdk

import { Docsy } from "@remcp/docsy-sdk";

const client = new Docsy();
const libraries = await client.searchLibrary("useEffect cleanup", "React");
console.log(libraries.map(({ libraryId, versions }) => ({ libraryId, versions })));

Explore the SDK reference and CLI reference for additional examples.

MCP for coding agents

MCP is a hosted service, not a local executable. Connect with an OAuth 2.1-capable MCP client and complete the sign-in prompt.

# Claude Code
claude mcp add --transport http docsy https://docsy.remcp.site/mcp/registry

# Codex CLI
codex mcp add docsy --url https://docsy.remcp.site/mcp/registry
codex mcp login docsy

An unauthenticated HTTP 401 from this endpoint is expected. For ChatGPT, Cursor and other client-specific instructions, use the full AI plugin setup guide.

Verified distribution channels

Surface	Current release	Install / source
TypeScript SDK	sdk-v0.1.2	@remcp/docsy-sdk on npm
Terminal CLI	cli-v0.1.4	@remcp/docsy-cli on npm
Gemini CLI	gemini-v1.0.0	Extension metadata

LibHunt	getremcp/docsy project page	Publicly listed and automatically approved 24 Oct 2026; SDK and CLI source
Claude Code community	Marketplace manifest	Install from GitHub; not official Anthropic marketplace approval

The ChatGPT plugin link is publisher-provided. Availability depends on the account and platform; no independent official marketplace approval is claimed. ChatGPT-specific setup and vetted release assets are maintained in the companion MCP plugin repository.

For direct directory links, outstanding reviews and the Smithery transition, see the public distribution status.

The Docsy MCP Plugin README tracks the wider community-directory review queue. Those submissions are not official client-store approvals.

CLI v0.1.4 depends on SDK v0.1.2. SDK and CLI releases are published through npm; their GitHub release pages identify immutable source tags and do not need duplicate package archives. A Gemini extension manifest is not a claim of official gallery approval.

Trust and release policy

This is a public release-only source snapshot, not the development repository. The private source is built and tested before approved files are promoted through a protected GitHub pull request. Tags are package-specific (sdk-vX.Y.Z, cli-vX.Y.Z, gemini-vX.Y.Z), and existing published npm versions remain immutable. The server's public documentation tools are read-only.
