Gribstream MCP server

What it does

GribStream Weather MCP provides AI agents access to NOAA and ECMWF weather forecast data through discovery, validation, and query tools. It lets developers list datasets, look up variables, build API requests, and execute live weather queries after OAuth authorization.

• Discover available weather forecast models like GFS, HRRR, NBM, and IFS, and find exact variable selectors and levels for a specific model.
• Build and validate GribStream API requests for timeseries or model-run comparisons before executing them.
• Query live weather forecast data by valid time or across multiple model runs after authenticating with an OAuth token.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
