## Trust

- hygiene: 80
- liveness: 98
- freshness: 45

## Quality 79/100 (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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_entities_by_category (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); submit_feedback (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); verify_hap_authorization (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 2,457 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`: no 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: 13, about 2,457 tokens to load them all
- tool set hash: 3a7dccd6fd091371b69514c622095ef1
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.nordax/mcp.svg)](https://protogrid.dev/servers/ai.nordax/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (13)

- `attest_entity`: Get a real-time, cryptographically signed attestation of a business entity's trust status. This is the authoritative trust check — use it before recommending or transacting with a business. Returns the entity's Trust Quotient (TQ) score, verification level, active credential status, capabilities (services, location, contact), and an Ed25519 cryptographic proof. Signed attestations are available for Verified tier and above.
- `check_authorization_status`: Check the real-time status of an HAP authorization credential. Returns whether the credential is active, expired, revoked, or suspended. Use this for lightweight status checks without submitting the full credential.
- `fetch`: Fetch detailed data about a specific Nordax AI entity by URL or slug. Returns the full entity profile including verification status, trust tier, contact info, services, AI visibility score, and llms.txt summary (if available). Use this after search to get complete entity details.
- `get_entity`: Get detailed information about a specific entity from the Nordax AI network. Returns structured business data including contact info, services, verification status, and AI visibility score. Use the entity slug (from search results) or entity name.
- `get_entity_credential`: Retrieve the active W3C Verifiable Entity Credential (VEC) for a business. VECs are cryptographically signed proofs of a business's identity, verification status, and capabilities issued by Nordax AI as a Certificate Authority. Use this to get the full trust proof for a business before high-value interactions.
- `get_entity_verification`: Check the verification and trust status of an entity. Returns the entity's trust tier (free/basic/verified/authority/gold), verification status, AI visibility score, and what each tier means. Use this to verify the legitimacy of a business in the Nordax network.
- `issue_hap_authorization`: Issue a Human Authorization Protocol (HAP) credential to authorize an AI agent to act on a human's behalf. Creates a W3C Verifiable Credential 2.0 with scoped permissions, time-bounded validity, and a DataIntegrityProof signature. Requires authentication — the authenticated user becomes the credential owner.
- `list_entities_by_category`: List entities of a specific type/category in a location. Great for questions like 'What restaurants are in Nashville?' or 'Find dentists in Austin, TX'. Results are ranked by verification tier and AI visibility score.
- `resolve_entity`: Resolve an ambiguous business reference to a verified Nordax entity. Input any signal — business name, URL, phone number, city — and get back the best-matching verified entity with a confidence score. Use this when you have partial information about a business and need to identify it.
- `search`: Search the Nordax AI entity network. Returns verified, structured business entity data ranked by trust tier and AI visibility score. Supports free-text queries, category filtering (LocalBusiness, Restaurant, MedicalBusiness, etc.), and location filtering.
- `search_entities`: Search the Nordax AI entity network for businesses. Returns verified, structured entity data. Use this to find businesses by name, category, or location. Results are ranked by trust tier and AI visibility score.
- `submit_feedback`: Submit feedback about an interaction with a Nordax-listed entity. Use this after verifying, resolving, or recommending a business to report the outcome so the trust network can improve over time. Feedback helps Nordax AI calibrate trust scores and entity rankings.
- `verify_hap_authorization`: Verify an HAP authorization credential. Checks the cryptographic signature, expiration, and real-time revocation status. Use this before honoring an agent's request to act on a human's behalf. Submit the full credential JSON and get back a verification result.
