What is llms.txt Builder?
Agent and crawler discovery files work best when they follow the llmstxt.org shape: one H1, a blockquote summary, then
sections with absolute markdown links. Guessing unverified “docs candidate” URLs just creates noise.
This builder fetches your URL, cleans the site name, quotes the meta description as the summary, collects same-origin links from nav/footer, probes high-value paths (docs, MCP, pricing, etc.), and only includes links that respond successfully. No generative AI — deterministic fetch/parse/probe only.
Use it as a starting draft. If you already have a curated /llms.txt (like ToolYour’s production file), merge carefully instead of overwriting.
What are common questions about llms.txt Builder?
What if llms.txt already exists?
The tool flags that the origin file is reachable so you can merge carefully.
Will it overwrite my live llms.txt?
No. It only returns a stub in the report. You publish manually after editing.
Will it list URLs that 404?
No. Candidate paths are probed; only reachable (2xx/3xx) links are included.
How is this different from MCP .well-known discovery?
llms.txt describes the website/product. /.well-known/mcp describes how to connect to an MCP server.
Is this as good as a hand-written llms.txt?
No. It follows the llmstxt.org shape with verified links. Curated positioning and product facts still need human edit.
Does this use generative AI?
No. The stub is built from title/meta, nav links, and HTTP probes of docs/API paths.
Is llms.txt a Google ranking factor?
No. It is a voluntary discovery convention for agents/crawlers.
