Stamp content with permanent, verifiable provenance. Hash locally, verify free forever.
Scored across 7 tools
Each tool targets a distinct operation: account provisioning, stamping, listing, verification, revocation, and the future escrow access control. There is no overlap in purpose, so an agent can reliably select the right tool based on the action needed.
Six of seven tools follow a clear verb_noun pattern (create_account, create_proof, grant_access, list_proofs, revoke_proof, verify_proof). 'reveal' is a bare verb without an explicit noun object, which is a minor deviation from the otherwise consistent style.
Seven tools is well-scoped for a proof-stamping service. It covers the full lifecycle (create, list, verify, revoke) plus account management and forward-looking escrow features, without being bloated or too sparse.
The core workflow is complete: create an account, stamp content, list proofs, verify proofs, and revoke proofs. The only gaps are minor: no account deletion or modification, and the escrow tools (grant_access, reveal) are placeholders for a not-yet-available feature, but they are clearly documented as such.
