## Trust

- hygiene: 100
- liveness: 100
- freshness: 85
- provenance: 85
- drivers: +repository +dns-namespace +website +reachable +uptime-100% ~updated-54d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: get_aurora_visibility (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_solar_flares_24h (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_current_kp (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 232 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: 4, about 232 tokens to load them all
- tool set hash: aafb12432acac724f2bea5b4f805006d
- badge: [![protogrid quality](https://protogrid.dev/badge/today.solarstorm/solarstorm.svg)](https://protogrid.dev/servers/today.solarstorm/solarstorm)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

## Tools (4)

- `get_aurora_visibility`: Aurora visibility outlook for a geographic latitude (degrees, e.g. 48.2 for Vienna): the Kp you need there, the expected maximum Kp in the next 24 h, and a verdict.
- `get_current_kp`: Current planetary Kp index: latest value, level (low/moderate/high/severe) and the observed 24-hour maximum.
- `get_kp_forecast_3day`: Official NOAA 3-day geomagnetic forecast: the maximum expected Kp per calendar day (Europe/Berlin days).
- `get_solar_flares_24h`: Solar X-ray activity of the past 24 hours from GOES: current flare class and the 24-hour peak class.
