View docs

You can use this MCP server to access weather data and actions in real time through Server-Sent Events, while also interacting with standard web endpoints. It combines a FastAPI web application with MCP integration, so you can stream updates and invoke tools like weather-related functions from an MCP client.

How to use

Connect an MCP client to the SSE endpoint to stream real-time events and post messages to the server. Use the standard web endpoints for human-facing pages and status checks, and use the MCP-enabled routes to discover tools and run actions.

Available tools

get_alerts

Fetch weather alerts from the MCP-enabled weather service, returning current alerts for configured regions.

get_forcast

Fetch weather forecast data from the MCP-enabled weather service for a specified location and time horizon.
