## Trust

- hygiene: 80
- liveness: 99
- freshness: 100
- provenance: 45
- drivers: +website +reachable +uptime-98% +updated-8d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (good)

### 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 3600000)

### 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: 86 (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
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: inspect_observing_spot (destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 401 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 50 (weight 15)

- pass `stability.changes`: 1 tool changes in 30 days
- fail `stability.rug_pull`: 1 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: 1, about 401 tokens to load them all
- tool set hash: b1250a21968ccc9488385401ff527020
- tools last changed: 2026-10-03T17:44:06.153Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.2pm-ninja/star-ninja.svg)](https://protogrid.dev/servers/io.github.2pm-ninja/star-ninja)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-03 `inspect_observing_spot` changed (title, description, inputSchema, annotations) **meaning changed**
  - before: Inspect your spot from your start and optionally select a returned night.
  - after: Checks stargazing conditions at one spot over the coming nights. Returns the spot's darkness band from light-pollution data, its straight-line distance from a start point with a rough drive time, and a map link. For each night: the cloud forecast, when full darkness starts and ends (some nights have none), the moonless hours, and how much of the Moon is lit. Use it when someone asks where or when they can see stars, to check a place they name or compare several. Both the start and the spot must be given as coordinates. It does not find, rank or recommend spots, or check access or safety.
