## Trust

- hygiene: 80
- liveness: 100
- freshness: 45

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (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: 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_current_aqi (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_annual_air_quality (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_tri_facilities (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 849 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: 5, about 849 tokens to load them all
- tool set hash: b56c21f331a401722778d074ae700480
- badge: [![protogrid quality](https://protogrid.dev/badge/com.olyport/epa.svg)](https://protogrid.dev/servers/com.olyport/epa)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `get_annual_air_quality`: Get annual air quality summary data for a US state.

    Returns annual statistics from the EPA Air Quality System (AQS),
    including mean concentrations, max values, and exceedance counts
    for the specified pollutant across all monitoring sites in the state.

    Args:
        state: Two-letter US state abbreviation (e.g. 'CA', 'NY').
        parameter: Pollutant to query. Options: 'PM2.5', 'Ozone', 'SO2', 'NO2', 'CO'.
                   Default is 'PM2.5'.
