MachineWitness MCP server: is this domain on the record?

MachineWitness is an evidentiary archive of the machine-readable web in theEuropean Union. Every day two independent witnesses record what public domainsserve to machines (robots.txt, ai.txt, TDM reservations, llms.txt, and theheaders and meta tags of the homepage) and seal that day into a publishedMerkle root with an external timestamp.

This server lets Claude, ChatGPT, Cursor or any MCP client ask whether a domainis observed, suggest one, and order a time-stamped record of public addresses,in the same conversation in which the question comes up. Hosted bymachinewitness.eu; this repository holds the publicmetadata, the server code is not open source.

A witness, not a detective

The archive records; it does not evaluate, rank or accuse. The tools answerwhether a domain is observed and from when. They never return file contents,and there is no way to list or search the observed set. A record states what anaddress delivered at a given time; it is not an assessment and not legal advice.
