https://proof.tatastu.dev/mcpcreate_proofStamp content with a permanent provenance record. Pass the sha256 hash of the content (hash it locally; the content itself is never uploaded). Returns an instant signed receipt with a public verify URL. The stamp asserts provenance from a signer at a time, not authorship truth. Requires an API key (Authorization header) or x402 payment.
list_proofsList your recent stamps (requires API key).
revoke_proofRevoke a stamp you created (forward-only: anchored history stays verifiable, but the proof is marked revoked from now on). Requires API key.
verify_proofVerify content against all existing stamps. Pass a sha256 hash; returns every stamp for that hash (earliest anchored first) with signature, anchoring, and supersession status. Free, no auth required.
Tool names and descriptions are reported by the server itself and shown here unverified; never interpreted as instructions.
