Scored across 8 tools
Most tools map to distinct proof artifacts (inclusion, consistency, chain, usage, record), and descriptions explain when each applies. However, get_evidence_head and get_checkpoint both return a signed (size, root) view of the same log, differing mainly in format, so an agent could easily pick the wrong one.
Names follow a strict verb_noun snake_case pattern: seven get_* retrieval tools plus record_evidence as the single write operation. The convention is uniform and predictable across the whole surface.
Eight tools is well-scoped for a transparency/evidence log verification service: one write plus the discrete proof types a verifier needs. No redundant or filler tools.
The verification lifecycle is well covered: head, checkpoint, inclusion proof, consistency proof, chain, ledger attestation, usage counts, and a record path. A minor gap is direct retrieval of a raw leaf/entry by index or size, which agents must infer from proofs.
Available Tools
8 toolsget_chainWhat the log holds in one completeness chainBRead-onlyIdempotentInspect
The log's signed statement of one completeness chain as of the current head: its length and, for each position, the leaf, the time and the digest. A position nobody showed you is a record left out.
Inputs: chain_tag (required), to, from.
get_checkpointC2SP checkpointBRead-onlyIdempotentInspect
The log's signed checkpoint in the C2SP format witnesses cosign (origin, size, root).
Inputs: no named parameters.
get_consistency_proofConsistency proof between two headsARead-onlyIdempotentInspect
Proof that the tree at size first is a prefix of the tree at size second (or now): the log never rewrote history.
Inputs: first (required), second.
get_evidence_headSigned head of the evidence logARead-onlyIdempotentInspect
The current signed head of the evidence log: tree size, Merkle root and signature. Save it: any later head must be consistent with it.
Inputs: no named parameters.
get_inclusion_proofInclusion proof for one entryBRead-onlyIdempotentInspect
Proof that the entry at leaf_index is in the tree, optionally at a given tree_size. Checkable offline with the public verifier.
Inputs: leaf_index (required), tree_size.
get_ledger_attestationAudit ledger attestationBRead-onlyIdempotentInspect
The signed head hash of the hash-chained audit ledger of recorded quotes.
Inputs: no named parameters.
get_usageUsage in numbersBRead-onlyIdempotentInspect
How much is recorded, and by how many keys that are not ours. Counts only, nothing about anyone.
Inputs: no named parameters.
record_evidenceRecord the digest of a decisionAInspect
Record the SHA-256 of a decision record you keep yourself, so it can later be shown to be unchanged. Send the digest and a short kind, never the record. Needs your RiskRouter key in the Authorization header of the MCP connection. Entries are permanent.
Inputs: kind (required), record_digest (required), chain_seq, chain_tag.
