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
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-v0.1.3	@remcp/docsy-cli on npm
Gemini CLI	gemini-v1.0.0	Extension metadata
MCP Plugin	Stable releases	Plugin / AI-client distribution
Official MCP Registry	io.github.getremcp/docsy	Active version 1.0.9 (24 Oct 2026)
Glama	Docsy remote MCP connector	Listed and publisher-claimed (24 Oct 2026); domain DNS verified and OAuth connection tested
Claude Code community	Marketplace manifest	Install from GitHub; not official Anthropic marketplace approval

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

CLI v0.1.3 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.
