# Severe Weather Alerts AI Agent Connect > Severe Weather Alerts MCP connects your AI agent to the National Weather Service API. It provides real-time access to every active watch, warning, and advisory across the United States. Your agent can pull specific alert details, check weather conditions at exact coordinates, or summarize national weather activity without needing an API key. ## Overview - **Category:** weather-climate - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_hj2uTJJPvK3W6KmTSkkEEYydxwwn5xOpSQIacPqc/ai-agent-connect - **Tags:** weather, nws, noaa, severe-weather, alerts, warnings, tornado, flood, watches, united-states ## Description This MCP gives your AI client a direct line to the National Weather Service. Instead of searching through news sites, your agent can pull official data on every active weather event in the country. You can ask it to find specific warnings for a single coordinate or get a high-level summary of all active alerts by state or event type. It handles the heavy lifting of parsing NWS data, including the forecaster's specific instructions and protective measures. Because it uses the official API, the data is as current as the NWS feed itself. The MCP is designed to be smart; it automatically filters out system test messages that usually clutter weather feeds, so your agent only sees actionable information. Whether you need to know if a tornado warning covers a specific latitude or you want a breakdown of marine alerts along the coast, this tool provides the raw, official data your agent needs to keep you informed. ## Tools ### list_active_alerts This tool lists all current weather watches, warnings, and advisories from the NWS. It returns alerts ranked by severity, including details on urgency, area, and expiration. ### summarize_active_alerts This tool provides an aggregated view of all active weather alerts across the US. It counts alerts by event, severity, urgency, and state to give your agent a quick national overview. ### get_alert_details This tool retrieves the full text of a specific weather alert. It provides the forecaster's product text, protective instructions, and official product identifiers. ### get_alerts_at_point This tool finds every active weather alert covering a specific latitude and longitude. It identifies the responsible NWS forecast office and the specific zone for that location. ### list_state_zones This tool retrieves the NWS forecast, county, fire, or marine zones for a specific US state. It provides the zone IDs used to tie alerts to geographic areas. ## Prompt Examples **Prompt:** ``` Are there any weather alerts for my location at 39N, 77W? ``` **Response:** ``` Nothing is in force at 39,-77 right now. That point falls in forecast zone MDZ504 under the NWS Sterling Virginia office (LWX), and no watch, warning or advisory covers it. ``` **Prompt:** ``` What does the current Flood Warning for Minnesota say? ``` **Response:** ``` Flood Warning FLSARX, issued by NWS La Crosse Wisconsin for Mower County, Minnesota. It is a Severe event with Expected urgency, in force until September 21 at 3:32 AM CDT. ``` **Prompt:** ``` How active is the weather across the country right now? ``` **Response:** ``` Most active alerts are currently marine-based, such as Small Craft Advisories and Gale Warnings. Nationwide, the most severe alerts are listed first, followed by counts by state and event type. ``` ## Capabilities ### Real-time Alert Monitoring Your agent can monitor active NWS watches and warnings as they are published. ### Geospatial Lookups The AI can check if a specific coordinate is inside a weather warning polygon. ### National Weather Summaries Your agent can aggregate weather data to report on total alert counts by state or event. ### Detailed Instruction Retrieval The AI can read the exact protective instructions provided by NWS forecasters. ### Zone Identification Your agent can look up specific county, fire, or marine zones for any US state. ## Use Cases ### Automated Safety Checks An agent checks a specific coordinate every hour to see if a new warning has been issued. ### Regional Weather Briefings An AI generates a summary of all active flood or tornado warnings for a specific state. ### Marine Activity Monitoring A user asks their agent to check for Small Craft Advisories along a specific coastline. ### Emergency Instruction Parsing An agent reads the full text of a warning to extract specific safety steps for a user. ## Benefits - Direct access to official NOAA NWS data without managing API keys. - Automatic filtering of system test messages to prevent false alarms. - Precise location matching using alert polygons rather than just state filters. - Reduced latency through aggregated summary tools for national views. ## How It Works Connecting to this weather data is a single-step process that makes official NWS data available to your agent. 1. Connect the MCP to your AI client via the Vinkius dashboard. 2. Your agent identifies the available weather tools. 3. You ask your agent a question about weather alerts or a specific location. 4. The agent calls the necessary tool to fetch data from the NWS. 5. The agent processes the official text and provides you with a direct answer. ## Frequently Asked Questions **Do I need an API key?** No. This reads the public National Weather Service API at api.weather.gov, which requires no key or account. **What is the difference between severity and urgency?** Severity grades the phenomenon itself — Extreme and Severe mean threat to life and property. Urgency grades how soon it matters: Immediate means act now, Expected means within a few hours, Future means well ahead. A Tornado Warning is severity Severe and urgency Immediate; a Flood Watch is typically severity Moderate and urgency Future. Results are ranked by severity first, then urgency. **Why are some alerts missing from the results?** The feed carries NWS system test messages that say "Monitoring message only. Please disregard." They are filtered out unless include_tests is set. Marine alerts — Small Craft Advisories, Gale Warnings — are genuine weather products and are always included; ask for a coastal point or a marine zone to see them. **Why did an alert id stop working?** An alert is removed from the API once it ends, so an id from an earlier call returns "no alert exists" rather than a stale record. List the alerts again to get the ids currently in force — the same alert may also have been reissued with a new id and an Update message type. **Can I filter to more than one place at once?** No — the NWS API rejects a request that carries both a state, a point and a zone. Choose one of them per call. To see alerts across several states, call summarize_active_alerts without a geographic filter and read the by_state table.
