This one needs environment variables set before it will start: NWS_USER_AGENT (User-Agent header for NWS API requests. The API requires this header but a default is provided.), MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').). The author declared them in the registry entry; get the values from the project itself.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

nws
nws_find_stations
Find weather observation stations near a location. Returns stations sorted by proximity with distance and bearing. Use to discover station IDs for nws_get_observations.
nws_get_forecast
Get the weather forecast for a US location. Returns either named 12-hour periods (default) or hourly breakdowns.
nws_get_observations
Get current weather observations (actual measured conditions). Accepts coordinates (resolves nearest station automatically) or a station ID directly (e.g., "KSEA").
nws_get_office_discussion
Get the latest narrative forecast product from a Weather Forecast Office (WFO). The default product is AFD (Area Forecast Discussion), which explains the meteorological reasoning behind the forecast — synoptic setup, model guidance, and forecaster confidence. Other types: HWO (Hazardous Weather Outlook, 1-7 day severe/flood/winter outlook), ZFP (Zone Forecast Product, zone-by-zone text), SPS (Special Weather Statement, short-fuse advisory). The office code is the 3-letter WFO identifier returned as the "office" field by nws_get_forecast.
nws_get_zone_forecast
Get the text forecast for a public NWS forecast zone. Returns named forecast periods (e.g., "Today", "Tonight", "Monday") with detailed narrative text — the human-readable, zone-level forecast written by local forecasters. Completes the alert-to-forecast chain: nws_search_alerts returns each affected zone in "affectedZones" as a code plus a type, and nws_find_stations returns codes in the "forecastZone" column. Only affectedZones entries with type "forecast" work here; entries typed "county" or "fire" have no text forecast upstream and will not resolve. Zone codes follow the pattern XXZ### (e.g., "WAZ315" for Western Washington lowlands).
nws_list_alert_types
List all valid NWS alert event type names. Use to discover valid values for the event filter in nws_search_alerts, or to browse alert categories. No parameters required.
nws_search_alerts
Search active weather alerts (watches, warnings, advisories) across the US. Filter by state, coordinates, zone, land/marine region, event type, severity, urgency, or certainty. area, point, zone, region_type, and region are mutually exclusive — provide at most one. Omit all filters for a national search.

Nws Weather MCP Server — questions

Answers built from our own checks of this server.

What can Nws Weather MCP Server do?
It exposes 7 tools, read directly from the server on our last check. Among them: nws_find_stations, nws_get_forecast, nws_get_observations, nws_get_office_discussion, nws_get_zone_forecast, nws_list_alert_types and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Nws Weather MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 350 ms. The bar chart above shows every period we have measured.
How do I connect Nws Weather MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Nws Weather MCP Server need an API key?
No. Nws Weather MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Nws Weather MCP Server?
It answers our handshake in 350 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Nws Weather MCP Server?
The npm package @cyanheads/nws-weather-mcp-server was installed 343 times in the last week. Week over week that is +36%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Nws Weather MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 1 stars on GitHub and 3 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
