## Trust

- hygiene: 80
- liveness: 99
- freshness: 85
- provenance: 45
- drivers: +dns-namespace +reachable +uptime-98% ~updated-60d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 100/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 60000)

### 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`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 252 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: 1, about 252 tokens to load them all
- tool set hash: f50eb247001e054dc8ba634cdff585a6
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.kaiv/dns-check.svg)](https://protogrid.dev/servers/ai.kaiv/dns-check)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `resolve_dns`: Resolve any DNS record live via Google Public DNS. Answers: is DNS propagated? What are the MX/TXT/SPF/DKIM records? Where does this CNAME point? For reverse lookup pass name=<reversed-ip>.in-addr.arpa with type=PTR (e.g. 90.57.149.3.in-addr.arpa for 3.149.57.90). Returns Status (0 = NOERROR, 3 = NXDOMAIN), Answer records with TTLs, and the AD flag for DNSSEC validation.
