Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

authorize_tool_callread-onlyCheck whether a DID.is delegation chain (compact JWTs, root first) allows an agent to call a given tool. Returns ALLOW or DENY with the verified chain. Read-only; nothing is stored.
evaluate_policyread-onlyEvaluate a DID against declarative rules (allowed methods, curves, domain binding, TLS, linked accounts, verifiable history, credential status). Returns PASS, FAIL or INDETERMINATE (not a pass). Read-only.
inspect_a2a_agentread-onlyFetch an A2A agent card (agent URL or card URL) and report its signature status, interfaces and skills. Read-only.
inspect_mcp_serverread-onlyInspect a remote MCP server over Streamable HTTP: protocol version, tool inventory fingerprints, declared annotations versus DID.is side-effect heuristics, and changes since the last observation. Read-only; never authenticates to the server.
resolve_didread-onlyResolve a DID (did:key, did:jwk, did:web, did:webvh) and report which evidence dimensions are established and which are not. Read-only; fetches the DID document from its origin.
search_directoryread-onlySearch the public DID.is directory of DIDs whose controllers proved control and chose to be listed. Matches names and domains. Read-only.
verify_credentialread-onlyVerify a W3C Verifiable Credential or SD-JWT VC (JSON object or compact string): signature, validity period and status list. Optional requiredClaims checks issuer-signed claim values. Read-only.

Schemas: list_tools.
