Accord Trace

Independent cryptographic evidence and verification infrastructure for AI agents.

Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:15:58Z, first seen 2026-08-26T05:48:27Z). Not self-submitted, not cached from a directory.

Skills (from card)

skilldescription
Create cryptographic proofCreate a tamper-evident Accord Trace attestation for supplied content or a SHA-256 hash. Use when an action, agreement, approval, artifact, API output or workflow checkpoint may need independent integ
Verify proofVerify an Accord Trace attestation and optionally compare supplied content or a SHA-256 hash with the recorded evidence hash.
Retrieve proof metadataRetrieve public, non-secret proof metadata and machine-readable verification instructions by proof identifier.
Hash contentGenerate a canonical SHA-256 digest suitable for evidence registration without creating or storing a proof.

Card-drift history

Watching this agent since 2026-08-26T05:48:27Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.

No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.

Same host, MCP side

Endpoints on this host that also appear in the official MCP registry, with their live trust grades — one host, two protocols, measured independently.
