## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 20 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3197 tokens (~159/item across 20 items; 20 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

    Examples: 'Nashville', '90210', 'WFMT', '101.1', 'country near Austin',
    'NPR near Boston'. Returns station list with frequency, callsign,
    city, format, and signal strength data.
    Source: FCC LMS (Licensing and Management System) for station data;
    Wikipedia for owner/brand and format enrichment. US only.

Input parameters:

- `lat`: Optional latitude in decimal degrees (e.g. 40.7128 for NYC). If provided with lon, restricts results to within radius_miles.
- `lon`: Optional longitude in decimal degrees (e.g. -74.0060 for NYC). Negative = West, positive = East.
- `query` (string, required): What to find: city ('Nashville'), ZIP ('90210'), callsign ('WFMT'), frequency ('101.1'), format/genre ('country'), or 'X near Y' like 'jazz near Boston'.
- `radius_miles` (integer): Search radius from the location in miles. Default 75.

### `fm_station_detail` (~96 tokens)

Get detailed information for a specific FM station by callsign.
    Returns frequency, power, antenna height, format, owner, website,
    location, and a coverage-map thumbnail image.
    Example: 'WFMT', 'KPBS-FM', 'CIRA-FM'.

Input parameters:

- `callsign` (string, required): FM station callsign, e.g. 'WFMT', 'KPBS-FM', 'CIRA-FM'.

### `fm_stations_by_format` (~241 tokens)

Find FM stations by format/genre category.
    Use this when you only have a format in mind and want to browse all
    stations of that format. Use find_fm_stations instead if you have a
    city or callsign — its query parameter also accepts format keywords.

    instead, which factors in VOACAP propagation prediction.
    Examples: '9330', 'BBC', 'Radio Havana', 'Spanish', 'Africa'.
    Sources: HFCC + EiBi shortwave schedule databases.

Input parameters:

- `query` (string, required): Search term: frequency in kHz ('9330'), broadcaster ('BBC'), language ('Spanish'), or target area ('Africa').
