## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 9 of 9 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,647 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 9, about 1,647 tokens to load them all
- tool set hash: b559ec450db07a5e64e1083456d0be1d
- tools last changed: 2026-10-07T15:06:27.663Z
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.ruthven/ruthven.svg)](https://protogrid.dev/servers/ai.ruthven/ruthven)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-07 `ruthven_agent_stage_records` added
  - 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.

## Tools (9)

- `ruthven_agent_stage_records`: 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`: 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_describe`: 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 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`: 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`: 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`: 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 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.
- `ruthven_verify_claim`: 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.
