llms.txt Validator

Validate any site's `llms.txt` against the llmstxt.org specification — checks structure, fetches every linked URL so broken links surface, and returns a 0-100 score with specific fixes. Also reports AI-discoverability signals (`robots.txt`, `llms-full.txt`, JSON-LD, spec-v2 `describedby` relations) and can scaffold a starter file from a homepage and sitemap. Hosted Streamable HTTP at `https://llms-txt-validator.dev/mcp`; no auth, no account. Tools: `validate_llms_txt`, `validate_llms_txt_content`, `generate_llms_txt`. In the official MCP Registry as `dev.llms-txt-validator/llms-txt-validator`.
