GribStream Weather MCP — Claude Code MCP server: setup guide
Connects AI assistants to NOAA and ECMWF numerical forecast models via GribStream. Useful for variable lookup, request validation, and live time series data.
claude mcp add --transport http mcp https://gribstream.com/mcpWhat GribStream Weather MCP does
This remote server runs over HTTP at https://gribstream.com/mcp. No local installation is needed. It gives coding assistants access to weather prediction datasets including GFS, HRRR, NBM, and ECMWF IFS. Public unauthenticated tools inspect model variables, resolve aliases, check expression syntax, and generate ready-to-run curl commands.
Fetching actual forecast values via /timeseries and /runs requires OAuth authorization linked to a GribStream API token. The endpoint uses a public PKCE flow where the client secret stays empty. MCP client forms that require a client secret cannot complete this handshake.
What it helps with
- locate exact variable selectors across NOAA and ECMWF datasets
- validate weather API request syntax and expression rules before sending
- retrieve numerical forecast values using
/timeseries - compare meteorological predictions across different model runs
Example prompts for the agent
- Find surface temperature selectors in the GFS forecast dataset
- Generate a valid curl command to fetch wind speed from ECMWF IFS
- Query precipitation accumulation from the latest HRRR cycle

Questions about GribStream Weather MCP
How to install GribStream Weather MCP in Claude Code?
Run claude mcp add --transport http gribstream-weather-mcp https://gribstream.com/mcp. The remote tools become available immediately without extra setup steps.
What does GribStream Weather MCP do?
It lets AI tools search weather datasets, identify model parameters, and validate queries for GribStream. It also executes authenticated queries for live numerical forecast data.
Is an API key required to use GribStream Weather MCP?
Metadata search, variable resolution, and query validation work without authentication. Live weather queries require an OAuth login tied to an active GribStream token.
