Attest MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 93 installs a week from npm. Last commit 21 Aug 2026.
Free proof-of-existence attestation for digital files, MCP tools for the imgauth service.
Today is the operative word: we check Attest MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
