Claude Code: ask. ### `ruthven_agent_stage_records` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text The acquisition records of a collection's AI Agents stage (ADR-010): every application as the stage's signer recorded it — the operator's signed declaration, the wallet, the ERC-8004 identity and its on-chain check, the quantity, the permission's salt and signer, the time — each hashed and a leaf of a Merkle root the collection's owner commits to the RuthvenAnchor registry on Ethereum. With record_id, one record with its proof and the steps to check it against the chain without trusting RUTHVEN. Records are operator-declared; the root proves a record is the one recorded, not that a statement in it is true. No model is involved. ``` ### `ruthven_ask` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Ask a question about one asset. Returns structured JSON only: an answer, claims (each with a verification state and the evidence ids it rests on), unknowns, the full cited evidence records, and follow-up questions. Never a valuation; never a recommendation to act. ``` ### `ruthven_verify_claim` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Given the evidence ids a claim rests on, return the state the claim earns (the weakest among them), each record's hash and location, and how to check it independently of RUTHVEN. Deterministic; no model is involved. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `ruthven_describe` - The name "ruthven_describe" says "describe": a word for reading. Description, as the server wrote it: ```untrusted-server-text What RUTHVEN is and what an agent may do with it: the verification states, the permission model (READ and ANALYSE only), the asset types (live and placeholder), and the JSON API endpoints. ``` ### `ruthven_get_asset` - The name "ruthven_get_asset" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The universal RUTHVEN asset record: identity, tokenization, provenance, source works, components, construction sequence, hashes, documents, rights, verified / contextual / inferred facts, unknowns, and counts. Claims carry evidence ids; pass include_evidence=true for the full evidence records as well (large). ``` ### `ruthven_get_evidence` - The name "ruthven_get_evidence" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve the source record behind a stable evidence id (EVID-…) or an unknown id (UNK-…): where it was read from, its hash, its state, and how fresh it is. ``` ### `ruthven_get_proof` - The name "ruthven_get_proof" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text A Merkle proof that evidence records are part of the issued Origin Passport, with the entry each rests on and the steps to check it without trusting RUTHVEN: SHA-256 over the entry, keccak256 up the proof, and the root compared with the one in the published Passport. It proves that the record contains the entry; it does not make a statement true. With neither evidence_ids nor paths, returns the paths that can be proved. Deterministic; no model is involved. ``` ### `ruthven_get_provenance` - The name "ruthven_get_provenance" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Provenance and lineage: the timeline, source works, generated elements, components, the construction sequence, relationships, chain identity, tokenization, and the evidence graph (cut_from, placed_as, pinned_as, pictured_by, hash_of). ``` ### `ruthven_list_evidence` - The name "ruthven_list_evidence" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The evidence records behind an asset, each with a stable evidence_id, its source (document, locator, ipfs uri, gateway url, ledger claim id), a SHA-256, a verification state and freshness timestamps. Filter by status (VERIFIED, CONTEXT, INFERRED), type, kind, or a text query. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `ruthven`: ```json { "permissions": { "allow": [ "mcp__ruthven__ruthven_get_asset", "mcp__ruthven__ruthven_list_evidence", "mcp__ruthven__ruthven_get_evidence", "mcp__ruthven__ruthven_get_provenance", "mcp__ruthven__ruthven_get_proof", "mcp__ruthven__ruthven_describe" ], "ask": [ "mcp__ruthven__ruthven_verify_claim", "mcp__ruthven__ruthven_ask", "mcp__ruthven__ruthven_agent_stage_records" ], "deny": [] } } ```
