Docsy MCP server

Docsy Plugin

Open-source plugin for current, source-linked developer documentation in Claude, OpenAI/ChatGPT/Codex and Cursor. It connects to the hosted read-only Streamable HTTP MCP endpoint:

https://docsy.remcp.site/mcp

The five public tools are resolve-library-id, query-docs, list-library-versions, search and fetch. Anonymous public lookups do not require a Docsy API key. Only public indexed documentation is accessible.

Verified public MCP registry listings

Docsy 1.0.5 is published as an active remote server in the official MCP Registry, registered as io.github.getremcp/docsy. The record references the organizational Streamable HTTP endpoint, https://docsy.remcp.site/mcp/registry, and this GitHub repository.

It is also available from the Docsy listing on Smithery, under getremcp/docsy. The Smithery publishing service accepted the release and discovered five MCP tools; directory health may be updated asynchronously.

These are MCP registry distribution channels. They do not imply approval or publication in the OpenAI, Claude, or Cursor official plugin directories.

For Claude Code, Docsy now provides an independent, user-installable community marketplace. These commands install the open-source package but do not imply an official Anthropic directory listing:

claude plugin marketplace add getremcp/docsy-plugin
claude plugin install docsy@docsy-community

For other MCP clients, use the remote endpoint https://docsy.remcp.site/mcp. The official registry manifest is kept in server.json.

Use Docsy in ChatGPT Work before public directory approval

You can connect the hosted read-only Docsy MCP privately; this does not publish Docsy in the universal OpenAI Plugins Directory.

to look up versioned documentation with source links.

1. Open ChatGPT → Plugins and select + → Add custom MCP server.
2. Name it Docsy, enter https://docsy.remcp.site/mcp/registry, and select No authentication.
3. Review the risk notice and approve the custom connection. Select Create as a plugin.
4. Under Personal, install the created plugin. Open ChatGPT Work and use @Docsy

Custom plugin creation, installation and trust approval are personal account actions. See the official OpenAI quickstart. OpenAI public directory review is a separate process and is not yet approved.

Codex CLI, VS Code and other MCP-capable clients

In Codex CLI add the remote server globally:

codex mcp add docsy --url https://docsy.remcp.site/mcp/registry
codex mcp get docsy

For VS Code, use MCP: Open User Configuration, then merge this server under the existing servers object. Do not replace other configured servers:

{
  "servers": {
    "docsy": {
      "type": "http",
      "url": "https://docsy.remcp.site/mcp/registry"
    }
  }
}

VS Code requires an MCP-enabled agent for tool use; adding a config does not mean it has been executed. Cursor supports equivalent user-level ~/.cursor/mcp.json configuration and the one-click link below.

For Cursor, use the documented one-click deep link (opens Cursor locally; it does not imply Cursor Marketplace approval):

Add Docsy MCP to Cursor

You can regenerate and verify the link with python3 scripts/publishing/cursor_deeplink.py.

Alternatively, add this remote server under MCP settings or in .cursor/mcp.json:

{"mcpServers":{"docsy":{"url":"https://docsy.remcp.site/mcp"}}}
