## Quality 80/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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: 75 (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: iss_position (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); earth_now (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); watch (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,091 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### 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
- pass `stability.new_links`: no tool change named a new site

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 9, about 1,091 tokens to load them all
- tool set hash: 8ea39a6688fead47004bb5080c46663d
- badge: [![protogrid quality](https://protogrid.dev/badge/io.sslip.13-62-217-51/earth-and-sky.svg)](https://protogrid.dev/servers/io.sslip.13-62-217-51/earth-and-sky)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (9)

- `earth_now`: One-shot summary of what is happening on Earth right now: 24h earthquake totals plus current ISS position.
- `earthquakes`: Recent earthquakes from USGS. Filter by window (hour/day/week/month), minimum magnitude, and place text. Returns magnitude, place, depth, time.
- `iss_position`: Current latitude/longitude of the International Space Station.
- `moon_phase`: Current (or given date's) moon phase and illumination for a location.
- `sky_at`: The real sky for a place and an instant: sunrise/sunset, moonrise/moonset, true moon phase and illumination, and the best dark window for stargazing. Pure astronomy, no API key.
- `sky_seeing`: Is tonight actually usable for stargazing or astrophotography? Combines real dark hours and true moon illumination (computed from first principles) with live hourly cloud cover, weighting low cloud above high cloud. Returns a 0-100 usability score per night hour, the best consecutive usable run, and a plain verdict. lat/lon required; tz_offset and when optional.
- `sky_tonight`: Real sky for a place and night: sunrise/sunset, moonrise/moonset, true moon phase and illumination, and the best dark window for stargazing. Computed from first principles (no key, no ephemeris file).
- `watch`: Stateful quake subscriptions. Unlike a local tool, the filter and its cursor are stored on the server, so poll returns ONLY events newer than your last poll - no re-scanning, no client-side dedupe. Actions: create (min_magnitude, place), poll (id), list, delete (id).
- `weather`: Current weather and the next 12 hours for a latitude/longitude, from Open-Meteo. No API key required.
