Agents

llms.txt dumps, and the pmndrs MCP server

Summary

Every site built with this generator also publishes machine-readable dumps of its content — and docs.pmnd.rs serves them to agents over MCP.

llms.txt

As alternate content, we provide you llms.txt and llms-full.txt.

These URLs are linked in the HTML header as:

<link rel="alternate" type="text/plain" href="/llms.txt" />
<link rel="alternate" type="text/plain" href="/llms-full.txt" />

MCP Server

llms-full.txt is a whole documentation site in one file — too big to paste into an agent for a one-line question. So docs.pmnd.rs also exposes it as an MCP server, which lets an agent read a table of contents first, then fetch the one page it needs.

One endpoint for all libraries, over streamable HTTP: https://docs.pmnd.rs/api/mcp. It exposes:

kindnamewhat it gives
resourcedocs://pmndrs/manifestwhich libraries are served, and how to query them
resourcedocs://{lib}/indexthat library's pages, one {path} - {title} per line
toolget_page_contentthe markdown of a single page, given a lib + a path from the index

A typical round-trip — "how do I use TypeScript with Zustand?":

Two pages transferred instead of the whole site.

Tip

pmndrs/claude-code-plugin supports it natively

/plugin marketplace add pmndrs/claude-code-plugin
/plugin install pmndrs@pmndrs

For other clients, see the JSON config in the MCP-server box on the home page. To poke at it by hand — see the resources, call the tool, read the raw JSON-RPC — run the official inspector:

$ HOST=127.0.0.1 npx -y @modelcontextprotocol/inspector

In the web UI it opens: Add Servers › Add manually, transport streamable-http, URL https://docs.pmnd.rs/api/mcp (or your own http://localhost:3000/api/mcp), and flip the server's toggle to connect.

Getting your library served

Only libraries publishing a /llms-full.txt dump are served — the ones badged MCP on docs.pmnd.rs. To join them:

  1. Publish the dump. If your site is already built with this generator, bump it to a version shipping /llms-full.txt and redeploy. Otherwise, either migrate to this generator, or emit that file yourself with the same XML shape (<page path="…" title="…">…</page>).
  2. Check it. curl -sI <NEXT_PUBLIC_URL>/llms-full.txt must return 200, and the body must contain <page …> entries. A missing dump makes the library's index resource fail loudly, on purpose.
  3. Flip the flag. Open a PR on pmndrs/docs setting llms_full: true on your entry in libs (src/app/page.tsx). That single flag drives the MCP badge, the docs://{lib}/index resource and the get_page_content enum. It takes effect once docs.pmnd.rs is redeployed — every push to main does that.
Note

This is a one-off. Once served, content updates need no redeploy on either side: pages are fetched at request time and revalidated every 5 minutes.
