## Tools (as reported by the server, not verified)

- `resolve\_did`: Resolve 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.
- `verify\_credential`: Verify 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.
- `inspect\_mcp\_server`: Inspect 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.
- `inspect\_a2a\_agent`: Fetch an A2A agent card \(agent URL or card URL\) and report its signature status, interfaces and skills. Read-only.
- `authorize\_tool\_call`: Check 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\_policy`: Evaluate 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.
- `search\_directory`: Search the public DID.is directory of DIDs whose controllers proved control and chose to be listed. Matches names and domains. Read-only.
