Web services

Section titled “Web services”

llmstxt.com a generator and a directory the site answers

removed from the list

Tools that did not exist on the check date were removed from the earlier version of this page: two WordPress generators, the Jeeves plugin, the llmstxt-parser package, the llms-txt-php library at its former address. The mcpdoc server was archived by its owner: llms.txt and MCP.

Directories of sites with llms.txt

Section titled “Directories of sites with llms.txt”

Directories collect the addresses of published files. The largest open one is llms-txt-hub. There are also llmstxthub.com and directory.llmstxt.cloud.

Use them with a caveat: entries age, and some listed sites no longer serve the file. A checked list: Who publishes llms.txt.

What to check after any tool

Section titled “What to check after any tool”
  1. The file answers 200 and is served as text.
  2. It has the site name and summary, not only a list.
  3. No service or private pages.
  4. Links have notes, and the notes make sense.
  5. It is clear when the file will be rebuilt next.

A generator does not know what matters on the site. Read an automatically assembled file and fix the selection: best practices, validation.
