## Quality 67/100 (needs work)

### protocol: 50 (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
- warn `protocol.transport`: only the legacy HTTP+SSE transport, deprecated until 2027-07-28
- 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: 64 (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
- 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: find_fm_stations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); fm_station_detail (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); fm_stations_by_format (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 3,869 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: 20, about 3,869 tokens to load them all
- tool set hash: acfa05f4b095bd601ec09c836530c467
- badge: [![protogrid quality](https://protogrid.dev/badge/com.dxtra/dxtra-radio.svg)](https://protogrid.dev/servers/com.dxtra/dxtra-radio)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

    Covers 832,000+ US amateur radio operators.
    Source: FCC Universal Licensing System (ULS) amateur archive

    plus a coverage thumbnail showing handheld / mobile / yagi reception
    contours from terrain-aware (ITM) propagation modelling.
    The 'stem' is the unique repeater key like 'KO4QJC~433_9000' (callsign
    plus frequency in kHz with underscore). Get stems from find_repeaters
    results — each repeater has a 'key' or 'stem' field.
    Example: 'W8MRC~146_7400'.
- `shortwave_live`: Find shortwave broadcasts receivable at a location right now
    (or at a specific UTC hour). Uses VOACAP propagation modeling to
    predict which broadcasts can actually be heard, not just what's
    scheduled. Returns frequency, broadcaster, language, target area,
    and predicted signal strength.
    Schedule sources: HFCC (High Frequency Coordination Conference)
    and EiBi shortwave database. Propagation: VOACAP.
- `shortwave_search`: Search the shortwave schedule database. Returns SCHEDULED broadcasts
    (what's listed in the operator schedules) — not what's actually receivable
    at a location right now. For "what can I hear from here", use shortwave_live
    instead, which factors in VOACAP propagation prediction.
    Examples: '9330', 'BBC', 'Radio Havana', 'Spanish', 'Africa'.
    Sources: HFCC + EiBi shortwave schedule databases.
- `tropo_status`: Get current tropospheric ducting conditions for FM radio DX.
    Returns whether enhanced propagation (tropo) is active, the tropo
    score, anomaly count, and details of any stations being received
    beyond normal range. Tropo ducting allows FM signals to travel
    hundreds of miles beyond their normal coverage.
- `tv_station_detail`: Get detailed information for a specific TV station by callsign,
    including channel, network, ERP, antenna height, and a coverage-map
    thumbnail image (Longley-Rice terrain-aware heatmap).
    Example: 'WABC', 'KCBS', 'WGN-TV'.
- `weather_radio_detail`: Get detailed information for a specific NOAA Weather Radio station
    plus a coverage thumbnail showing handheld / portable / fixed reception
    contours from terrain-aware (ITM) propagation modelling.
    The 'stem' is the unique key like 'WXK86~162_550' (callsign plus
    frequency in kHz with underscore). Get stems from find_weather_radio
    results — each station has a 'key' or 'stem' field.
    Example: 'KIH26~162_550', 'WXK86~162_550'.
