Any site's llms.txt: find the covering index, read its linked docs as markdown, search sections. Remote MCP server over Streamable HTTP at
https://llmstxtmcp.dev/mcp. Free, no API key. Tools:llms_index,llms_page,llms_search. The tool list is fixed per version.
Given any site or page URL, llms_index discovers the llms.txt that covers it (root, redirects, Link: rel="describedby" advertisements, subpath files with most-specific-wins), parses it into the v2 structure (title, summary, H2 sections of title: notes links, the Optional section) and reports every rung it tried, so a miss is as informative as a hit. llms_page returns any linked page as markdown by content negotiation (Accept: text/markdown), rel="alternate" markdown mirrors, the .md / .html.md / index.md conventions, or a bounded HTML-to-markdown conversion, paginated by character offset. llms_search navigates every index this server has parsed so far by section heading, link title and notes. Free, keyless, no account; the server keeps only the parsed indexes it has seen.
Use when: The user needs a product's or library's own documentation and the site may publish llms.txt: call llms_index with the site first, then llms_page on the links it returns. Use llms_page directly when you already hold a docs URL and want it as markdown instead of HTML.
Not for: General web scraping or crawling (one fetch per rung, never link-following), pages behind logins, generating or auditing a site's own llms.txt, or searching the whole web for documentation.

| Tool | Purpose | Effects |
|---|---|---|
llms_index | Find and parse the llms.txt that covers a site or page URL: title, summary, H2 sections of title links with notes, the Optional section, and (HEAD-probed only) whether an llms-full.txt exists. Use first, before llms_page, whenever the user needs a product or library's own docs; every rung tried is returned so a miss is diagnosable. | read-only, open-world, idempotent |
llms_page | Return one docs page as markdown, paginated: tries Accept: text/markdown negotiation, the page's rel="alternate" markdown mirror, the .md / .html.md / index.md conventions, then a bounded HTML-to-markdown conversion. Use on the URLs llms_index returns, or on any docs URL you already hold. | read-only, open-world, idempotent |
llms_search | Search the llms.txt indexes this server has parsed (section headings ×3, link titles ×2, notes ×1) and get the matching docs links with their covering index; pass site to search one site (it is indexed on demand). Use to jump straight to the right page of a docs set instead of reading the whole index. | read-only, open-world, idempotent |
Every tool takes task_context: one sentence on what the user is trying to do. It is required.

This page documents a server. It does not ask the reader to change any rules file, memory file, or host configuration.
Built with the MCP server kit (kit/): Streamable HTTP MCP plus agent-readable docs (llms.txt, server.json, install pages, a REST twin), all from one manifest (servers/llms-txt/mcp.factory.json). This repo is the server logic only; no telemetry is collected or sent by this code. MIT.
