What it can do

Tool	What it says it does
`explain_receipt`	Verify a run receipt and narrate the result in plain language: what the run recorded, which chains recomputed, where the first divergence is, and what an auditor can and cannot conclude without the producing install's keys.
`explain_trace_mapping`	How a bernstein run maps onto a TRACE v0.2 Trust Record: one row per claim with the journal field it is sourced from and the rule that derives it. Pass a run receipt to fill in the rows its embedded journal can answer (subject, iat, model, data_class, policy digest, tool transcript) alongside the…
`get_preset`	Every field of one compliance preset as bernstein v3.19.2 resolves it.
`list_adapters`	The agent adapters bundled with bernstein v3.19.2: adapter name, the binary it drives, the module that implements it.
`list_presets`	The compliance presets bernstein v3.19.2 ships, with the switches each one turns on.
`server_info`	Identity, version, and request limits for this MCP server.
`trace_verify_record`	Verify a TRACE v0.2 Ed25519 Trust Record locally with optional caller public key and freshness controls. Nothing is fetched. Embedded keys establish internal consistency only; revocation is not affirmed.
`verify_agent_manifest`	Agent Manifest v0.2 conformance checks on one manifest, stateless, no account: schema (vendored agent-manifest.schema.json), profile context, version, canonicalization, COSE envelope signature (Ed25519, key identified by kid in the protected header; ML-DSA-65 is reported unverifiable). Optionally…
`verify_chain`	Walk bernstein chain rows and recompute every link: journal rows (event_hash), lineage spine entries (entry_hash) or audit events (prev_hmac linkage). The row kind is detected from the fields, or pass `kind` explicitly. Reports the first divergent index. Pass `entries` as the file text (a JSON…
`verify_delegation_chain`	TRACE v0.2 delegation-chain conformance, stateless, no account: index every Trust Record by the RFC 8785 digest of its complete form, start at the leaf, follow delegation.parent_record_hash to the root, and check each hop's signature, the root key against `trusted_root_keys`, the depth bound, the…
`verify_receipt`	Recompute every hash chain a bernstein run receipt embeds (journal, lineage spine, optional audit range), rebuild the signed subject from the recomputed heads, and check the Ed25519 signature with the key the receipt carries. Needs no secret and reads nothing but the receipt. Returns the verdict…
`verify_trace_record`	TRACE v0.2 conformance checks on one Trust Record, stateless, no account: schema (vendored trace-claim.json), profile, subject URI, software-only runtime rule, policy digest, public-only confirmation key, the embedded signature (EdDSA, ES256 or ES384 with the key in cnf.jwk), appraisal, delegation…
