## Quality 82/100 (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: 79 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- 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: get_air_quality (destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 308 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 308 tokens to load them all
- tool set hash: b778eaa36702b457d5cf0e7d9b9de740
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Lulu-The-Narwhal/air-quality-mcp.svg)](https://protogrid.dev/servers/io.github.Lulu-The-Narwhal/air-quality-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `get_air_quality`: Get the current air quality for a city, from real-time monitoring
and atmospheric model data. Use for any "what's the air quality in X",
"is it safe to go outside in Y", "how polluted is Z" style question, or
whenever pollen/smog/wildfire-smoke/pollution conditions are relevant
to a plan (running, cycling, sensitive-groups advice, travel).

`city` is a free-text place name (e.g. "Bangkok", "Berlin", "Springfield, US").

Returns a dict with:
- `location`: resolved place name/country/admin1
- `us_aqi`: the current US Air Quality Index (0-500+)
- `aqi_category`: plain-language category computed from `us_aqi` --
  "Good" (0-50), "Moderate" (51-100), "Unhealthy for Sensitive Groups"
  (101-150), "Unhealthy" (151-200), "Very Unhealthy" (201-300), or
  "Hazardous" (301+); "Unknown" if no AQI could be resolved for that
  location
- `pm2_5`, `pm10`: particulate matter concentrations (ug/m3)
- `ozone`, `nitrogen_dioxide`, `sulphur_dioxide`, `carbon_monoxide`:
  trace gas concentrations (ug/m3)
- `local_time`: the timestamp of the reading, in the location's local time
- `attribution`
