Overview

AI-generated overview

Validates a website's llms.txt file against the spec, fetching every linked URL and returning a 0-100 score.

What it does
This remote MCP server checks an llms.txt file for a site against the llms.txt specification. It fetches the file and every URL it links to, then reports a score from 0 to 100. The registry description lists no individual tool names, so the exact tool surface is not documented here.
When to use it
Useful when you maintain or review an llms.txt file and want a quick automated check that its links resolve and its structure conforms to the spec. Handy before publishing or after changing a site's llms.txt.
Requirements
A remote streamable HTTP endpoint at the provider's domain; no package, account, API key, or environment variable is declared. Network access is needed so the server can fetch the target site and its linked URLs.
Before you install
The server fetches the target site and every URL listed in its llms.txt, so those addresses are sent to a third-party service. No credentials are requested by the manifest. Only point it at sites you are comfortable having fetched externally.
