llms.txt

llms-txt MCP server

Generates an llms.txt from a directory of Markdown or from a local sitemap.xml, and checks an existing llms.txt against the convention. Reads local files only; never writes and never fetches a URL.

Part of dev-mcp-servers. Stdio transport only; the server never opens a port.

Tools

generate_from_sitemap	path, title, description?, details?, include_prefix?, exclude_prefix?, optional_sections?, max_urls?	One link per <url>, grouped by first path segment, titles derived from the URL (pages are not fetched).
check_llms_txt	path or content	Errors, warnings and info with line numbers: single H1 first, blockquote summary, H2 sections of - [name](url): notes, no deeper headings, no duplicates, modest size.

Install

Claude Code:

claude mcp add llms-txt -- docker run --rm -i -v "$PWD:/work:ro" ghcr.io/basitalisandhu/mcp-llms-txt:0.2.2

Add -s user to make it available in every project. Any client that reads .mcp.json (Claude Code, Claude Desktop, Cursor):

{
  "mcpServers": {
    "llms-txt": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "-v", "/path/to/your/project:/work:ro", "ghcr.io/basitalisandhu/mcp-llms-txt:0.2.2"]
    }
  }
}

Pin the version as shown so that an update cannot change what runs in your editor without you noticing. The container sees only the mounted directory, so pass paths under /work. The package is not on npmjs.com yet, so npx does not work; see the repository README for GitHub Packages npm. From a checkout, use "command": "node", "args": ["<path>/packages/llms-txt/dist/index.js"] after npm install && npm run build at the repository root.

What it touches

• Network: None.
• Local files: Reads Markdown files under the directory you name (up to 1000 files, 1 MB each, 12 levels deep) or the one sitemap or llms.txt you name (up to 2 MB).
• Telemetry: none.

Notes

• The output is returned as text; write it to llms.txt yourself after reviewing it.
• Sitemap-derived files have empty notes because page content is not fetched; fill them in before publishing.

Build and test

npm install        # at the repository root
npm run build -w @basitalisandhu/mcp-llms-txt
npm test -w @basitalisandhu/mcp-llms-txt

Tests use node:test and the SDK's in-memory transport; they do not reach the network.
