## Trust

- hygiene: 100
- liveness: 99
- freshness: 100
- provenance: 90
- drivers: +repository +namespace-matches-repo +dns-namespace +reachable +uptime-98% +updated-16d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## 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: discover_domain (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); connect_domain (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_readiness (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 627 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`: 5 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: 3, about 627 tokens to load them all
- tool set hash: 19963ef365eb1dfbd78956ec467694ab
- tools last changed: 2026-10-04T05:55:12.492Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.nessgate/nessgate.svg)](https://protogrid.dev/servers/com.nessgate/nessgate)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-04 `discover_domain` changed (description)
  - before: Given a domain, read whatever it publishes at the standard machine-discovery locations (llms.txt, /.well-known/ard.json, /.well-known/agent-card.json, /.well-known/api-catalog, ai-info.json, openapi.json, and more) and return one normalized answer. Each resource keeps a sourceUrl pointing back to the domain so the caller can verify. NessGate reads the domain live and stores nothing; it makes no ownership or safety claim.
  - after: Given a domain, read whatever it publishes at the standard machine-discovery locations (llms.txt, /.well-known/ard.json, /.well-known/agent-card.json, /.well-known/api-catalog, ai-info.json, openapi.json, and more) and return one normalized answer. Each resource keeps a sourceUrl pointing back to the domain so the caller can verify. NessGate reads the domain live and stores no discovered domain or resource data; it makes no ownership or safety claim.
- 2026-09-29 `check_readiness` changed (description)
  - before: Given a domain, return each connectable resource it publishes with a readiness assessment (ready | credentials-required | incomplete, with the exact missing field) read from the service's own metadata. Client-agnostic; read-only. Use connect_domain when you know the client's capabilities.
  - after: Given a domain, return each connectable resource it publishes with a readiness assessment (ready | credentials-required | incomplete | broken, with the exact missing field) read from the service's own metadata. Client-agnostic; read-only. Use connect_domain when you know the client's capabilities.
- 2026-09-29 `connect_domain` changed (description)
  - before: Given a domain AND the calling client's capabilities, return HOW the client can connect: one outcome (ready | credentials-required | incomplete | no-compatible-method) with a connection plan (protocol, endpoint, transport, version, and the auth metadata the service published — e.g. the OAuth authorize/token endpoints and scopes), or the exact missing field when the service under-publishes. Deterministic matching, no scores. Read-only; credentials stay with the caller and are never sent to NessGate.
