MachineWitness
Machine access: MCP server and HTTP API
Query the archive from software. An MCP endpoint for assistants like Claude and ChatGPT, plus a plain HTTP API: ask whether a domain is observed, and suggest one for observation. No key, no registration.
This archive records what the web tells machines. Since October 2026 software can also order a point-in-time record; it prepares a payment, nothing more. If you use Claude, ChatGPT, or anything else that speaks the Model Context Protocol , add this endpoint and the two tools appear in your conversation. It uses the Streamable HTTP transport and is stateless: no session to establish, no stream held open, no credentials.
