Fetch METARs, TAFs, PIREPs, and SIGMETs/AIRMETs from the NWS Aviation Weather Center.
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. How we score →
Endpoint Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1166 tokens (~233/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

aviation_find_stations Find Aviation Weather Stations ~205
Resolve an airport or weather reporting station by ICAO identifier, or discover stations within a bounding box or US state. Returns all identifier variants (ICAO/IATA/FAA), coordinates, elevation, and available data types (METAR, TAF, SYNOP, etc.). Station IDs must be 4-letter ICAO format (e.g., KSEA, KJFK). At least one of station_ids, bbox, or state is required.
| Name | Type | Req | Description |
|---|---|---|---|
| bbox | object | — | Geographic bounding box for spatial queries. |
| state | string | — | Two-letter US state abbreviation (e.g., "WA") to list all stations in that state. |
| station_ids | array | — | One or more 4-letter ICAO station IDs (e.g., KSEA, KJFK). The upstream API only accepts ICAO format — 3-letter IATA codes (e.g., SEA) will return no results. Use bbox or state to discover ICAO IDs by… |
| Name | Type | Req | Description |
|---|---|---|---|
| stations | array | yes | Matching stations. |
No examples provided.
aviation_get_advisories Get Active Aviation Advisories (SIGMETs / AIRMETs) ~284
Get active SIGMETs and AIRMETs for a region. Returns each advisory with hazard type (CONVECTIVE, TURBULENCE, ICING, IFR, MTN OBSCN, etc.), severity, altitude range, valid period, polygon coordinates, and raw text. Coverage is US-centric (NWS Aviation Weather Center). During fair-weather periods no advisories may be active — an empty result is normal, not an error. Filter by advisory_type, hazard, or bbox.
| Name | Type | Req | Description |
|---|---|---|---|
| advisory_type | string | — | Filter by advisory type. "sigmet" includes convective SIGMETs. "airmet" includes AIRMET Sierra (IFR/mountain obscuration), Tango (turbulence), and Zulu (icing). "all" returns both. |
| bbox | object | — | Geographic bounding box to filter advisories by polygon overlap. |
| hazard | string | — | Optional hazard filter. CONVECTIVE = convective SIGMETs; TURBULENCE = AIRMET Tango; ICING = AIRMET Zulu; IFR = AIRMET Sierra (IFR conditions); MTN OBSCN = AIRMET Sierra (mountain obscuration); SURFAC… |
| Name | Type | Req | Description |
|---|---|---|---|
| advisories | array | yes | Active advisories matching the filter criteria. May be empty during fair weather periods. |
No examples provided.
aviation_get_metar Get METAR Weather Observations ~169
Get current weather observations (METARs) for one or more airports. Returns decoded fields — wind direction/speed/gusts, visibility, ceiling, temperature, dewpoint, altimeter, cloud layers — plus the computed flight category (VFR/MVFR/IFR/LIFR) and the raw METAR string. Accepts 1–10 ICAO station IDs (e.g., KSEA, KJFK). Use aviation_find_stations to resolve or verify an ICAO ID, or to discover nearby stations.
| Name | Type | Req | Description |
|---|---|---|---|
| hours | integer | — | Hours of observation history to return (1–12). Default 1 returns only the most recent observation per station. |
| station_ids | array | yes | ICAO station IDs to query. 1–10 stations per call. |
| Name | Type | Req | Description |
|---|---|---|---|
| observations | array | yes | Weather observations, one per station/time pair. Multiple entries per station when hours > 1. |
No examples provided.
aviation_get_pireps Get Pilot Reports (PIREPs) ~251
Get recent Pilot Reports (PIREPs) near an airport or within a bounding box. Returns decoded turbulence, icing, and cloud reports with altitude, aircraft type, intensity, and the raw PIREP string. Requires either station_id (ICAO center point for radial search, e.g., KSEA) or bbox (area search) — not both. Coverage is US-centric; PIREPs are sparse and absence of reports does not imply smooth conditions.
| Name | Type | Req | Description |
|---|---|---|---|
| altitude_max_ft | integer | — | Filter by maximum altitude in feet MSL (e.g., 35000 for FL350). Optional. |
| altitude_min_ft | integer | — | Filter by minimum altitude in feet MSL (e.g., 18000 for FL180). Optional. |
| bbox | object | — | Geographic bounding box for area PIREP search. |
| distance_nm | integer | — | Search radius in nautical miles around station_id. Only used when station_id is provided. Default 100. |
| hours | integer | — | How many hours of history to return. Default 3. |
| station_id | string | — | ICAO station ID as center point for radial search (e.g., KSEA). Use with distance_nm. |
| Name | Type | Req | Description |
|---|---|---|---|
| pireps | array | yes | Pilot reports matching the search criteria, ordered by observation time descending. |
No examples provided.
aviation_get_taf Get Terminal Aerodrome Forecast (TAF) ~133
Get the Terminal Aerodrome Forecast (TAF) for one or more airports. Returns each forecast period with valid times, wind, visibility, decoded weather conditions, and cloud layers, plus the raw TAF string. TAFs cover the next 24–30 hours and are issued only for airports with scheduled commercial service; check data_types from aviation_find_stations to confirm TAF availability. Accepts 1–4 ICAO station IDs (e.g., KSEA, KJFK).
| Name | Type | Req | Description |
|---|---|---|---|
| station_ids | array | yes | ICAO station IDs to query. 1–4 stations per call. |
| Name | Type | Req | Description |
|---|---|---|---|
| forecasts | array | yes | TAF forecasts, one per requested station. |
