libdocs-remote

libdocs-remote is the hosted variant of the library-docs lookup. Instead of calling a REST API locally, it forwards each request as a JSON-RPC tools/call to the hosted Context7 remote MCP endpoint at https://mcp.context7.com/mcp and returns the answer it gets back. It understands both plain JSON answers and text/event-stream (SSE) answers, reading the JSON-RPC payloads out of the data: lines.

Use it when you want the hosted service to do the work and only need a local stdio server (or a small CLI) in front of it.

CONTEXT7_API_KEY is optional. When it is set, it is sent as the CONTEXT7_API_KEY header documented for the hosted endpoint; when it is absent, no such header is sent and that is not an error.

Tools

Upstream failures — HTTP errors, JSON-RPC errors, unreachable hosts — are reported as tool errors with the underlying message.

Development

npm install
npm run build
npm test
npm run dev

Tests run entirely on fake-fetch fixtures, including plain-JSON and SSE upstream bodies; no network is used.
