MachineWitness MCP server

MachineWitness MCP server: is this domain on the record?

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

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

A witness, not a detective

The archive records; it does not evaluate, rank or accuse. The tools answer whether 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 an address delivered at a given time; it is not an assessment and not legal advice.

Privacy

The tools ask only for what their purpose needs: a domain, a reply address for a suggestion, addresses to record and a delivery address for an order. Never a purpose or a matter. What is kept and for how long: machinewitness.eu/privacy
