- freshness: 100
- provenance: 90

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 75/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 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`: 6 of 6 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,513 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 15 tool changes in 30 days
- fail `stability.rug_pull`: 3 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 6, about 2,513 tokens to load them all
- tool set hash: e9a45e7331adafab1666da57a8cfb041
- tools last changed: 2026-10-05T09:31:12.142Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.tjcgraham-rgb/gaip-trust-assurance.svg)](https://protogrid.dev/servers/io.github.tjcgraham-rgb/gaip-trust-assurance)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-05 `gaip_receipt_export` changed (inputSchema)
- 2026-10-04 `gaip_incident_bundle` changed (inputSchema)
- 2026-10-01 `gaip_check_sar_receipt` added
  - Use this when handed an x402 SAR-shaped receipt (draft proposal shape; may change). Pass `sar_receipt`, optionally the issuer's `public_key`. Returns missing fields, whether receipt_id matches the core and whether the signature checks out against that key. Free, read-only, no account; inputs must be public and non-personal.
- 2026-10-01 `gaip_receipt_export` changed (description)
  - before: Use this when you need a GAIP receipt in another format. Pass `receipt_id` and `format`: x402 (attestation style), erc8004 (validation-response shape) or vc (W3C-VC-like JSON-LD). Unsigned; integrity via hash chain and Merkle proof; no on-chain write. Free, read-only, no account; inputs must be public and non-personal.
  - after: Use this when you need a GAIP receipt in another format. Pass `receipt_id` and `format`: x402 (attestation style), erc8004 (validation-response shape) or vc (W3C-VC-like JSON-LD). Ed25519-signed when the runtime key is available; hash chain and Merkle proof; no on-chain write. Free, read-only, no account; inputs must be public and non-personal.
- 2026-10-01 `inspect_counterparty_evidence` changed (inputSchema)
- 2026-09-29 `gaip_incident_bundle` changed (description, inputSchema)
  - before: Something went wrong with an agent and you need the facts in order? Pass the `receipt_ids` you hold and attributed `observations` ({source, statement, observed_at_utc}). GAIP verifies each receipt, orders a timeline, attributes every entry to its source and adds an EU AI Act Article 73 reference aid. No fault, cause or liability finding; not a regulatory filing. If BLOCKED, read `hint`. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).
  - after: Use this when something went wrong with an agent and you need the facts in order. Pass the `receipt_ids` you hold and attributed `observations`. Returns a verified, source-attributed timeline with an EU AI Act Art. 73 reference aid. No fault, cause or liability finding. Free, read-only, no account; inputs must be public and non-personal.
- 2026-09-29 `gaip_evidence_pack` changed (description, inputSchema) **meaning changed**
  - before: An insurer, auditor or buyer asking what evidence exists about an agent or supplier? Pass its `subject` (public id or https URL), an optional `scope` (receipt_ids, since/until, categories, max_items) and optional `requester` (continuity_handle to include your own receipts). Get conformance, watch, witness, repair and incident records, each with a verify URL and Merkle proof, a manifest of counts and gaps, and a reference table of where it may help locate evidence for AIUC-1 / ISO/IEC 42001 reviews. An evidence compilation, not a certification or advice. If BLOCKED, read `hint`. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).
  - after: Use this when an insurer, auditor or buyer asks what evidence exists about an agent or supplier. Pass its `subject` (public id or https URL). Returns conformance, watch, witness, repair and incident records with Merkle proofs, plus gaps. A compilation, not certification or advice. Free, read-only, no account; inputs must be public and non-personal.
- 2026-09-29 `verify_gaip_receipt` changed (title, description, inputSchema, annotations)
  - before: Verify any GAIP receipt ID: retained history, hash chain and Merkle inclusion proof. Integrity only; it does not make the underlying claim true. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).
  - after: Use this when you hold a GAIP receipt_id and want to confirm it ("is this receipt genuine?"). Returns the retained record, hash chain and Merkle inclusion proof. Integrity only: it does not make the underlying claim true. Free, read-only, no account; inputs must be public and non-personal.
- 2026-09-29 `gaip_receipt_export` changed (description, inputSchema)
  - before: Need a GAIP receipt in another ecosystem's shape? Pass `receipt_id` and `format`: `x402` (Settlement Attestation Receipt proposal style), `erc8004` (validation-response shape for off-chain publication) or `vc` (W3C-VC-like JSON-LD). Unsigned: integrity via hash chain and Merkle proof only; no on-chain write. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).
  - after: Use this when you need a GAIP receipt in another format. Pass `receipt_id` and `format`: x402 (attestation style), erc8004 (validation-response shape) or vc (W3C-VC-like JSON-LD). Unsigned; integrity via hash chain and Merkle proof; no on-chain write. Free, read-only, no account; inputs must be public and non-personal.
- 2026-09-29 `inspect_counterparty_evidence` changed (title, description, inputSchema, annotations)
  - before: Need evidence about an agent before you delegate to it? Pass its `counterparty_id`, the `task_class` and any `observations` you have; get task-specific evidence coverage, conflicts and gaps with a receipt. No universal trust score or decision. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).
  - after: Use this when asked what evidence exists about an agent before delegating to it. Pass its `counterparty_id` and any `observations`. Returns task-specific evidence coverage, conflicts, gaps and GAIP's own earlier checks of it, with a receipt. Never a trust score or recommendation. Free, read-only, no account; inputs must be public and non-personal.
