- 02Original-source links in results
- 03Library ID and version discovery
- 04Search, query, and fetch tools
- 05Read-only documentation access
Use cases
- 01Check API documentation for a specific version
- 02Find official documentation for a library
- 03Verify an AI-generated documentation answer against sources
MCP support
Docsy provides five read-only tools through a hosted remote MCP service. MCP clients connect to its endpoint and authorize with OAuth 2.1.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Servers that need sign-in will prompt on first connect.

Choose how to use Docsy
| AI assistants | Developer tooling |
|---|---|
| Docsy AI / MCP Plugin → — connect ChatGPT, Claude Code, Codex or Cursor | Docsy SDK & CLI → — install TypeScript SDK, npm CLI or Gemini CLI extension |
These are separate release repositories for the same remote Docsy service. Neither contains private crawling infrastructure.
Source-linked documentation for AI
Docsy retrieves current and version-specific developer documentation for libraries, frameworks and SDKs. Results include original source links instead of untraceable summaries.
Five read-only MCP tools: resolve-library-id, list-library-versions, query-docs, search and fetch.
Connect
Canonical remote MCP endpoint: https://docsy.remcp.site/mcp/registry
The hosted MCP service requires OAuth 2.1 account authorization. Complete the sign-in prompted by your client. Existing clients may continue to use https://docsy.remcp.site/mcp.
| Client | How to connect |
|---|---|
| ChatGPT | Add Docsy as a remote MCP connector where supported, then authorize. |
| Claude Code | Run the command below. |
| Codex CLI | Add the server and log in with the commands below. |
| Cursor, VS Code and other MCP clients | Use the remote HTTP URL in MCP settings. |
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
Claude Code community marketplace
claude plugin marketplace add getremcp/docsy-plugin
claude plugin install docsy@docsy-community

Security and project scope
This is Docsy's public release-only repository. It contains vetted plugin manifests, skill metadata, approved artwork and installation instructions. Backend code, databases, crawlers and deployment infrastructure live outside this public distribution.
- Read-only documentation tools. Docsy cannot inspect private repositories or execute commands on your device.
- Account-scoped OAuth. Review and revoke sessions from Connected applications.
- Traceable releases. Use immutable version tags and attached assets instead of unreviewed development branches.
- Public REST and remote MCP differ. REST documentation lookups may be anonymous within rate limits; remote MCP requires OAuth.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
