GribStream Weather MCP is a hosted Model Context Protocol server for AI access to weather forecast data from GribStream, including NOAA and ECMWF model output.
It helps AI agents discover forecast datasets such as NOAA GFS, HRRR, and NBM or ECMWF IFS, resolve exact forecast variables and levels, validate request bodies, build runnable GribStream Weather API requests, and execute live read-only weather queries after OAuth authorization.
NOAA and ECMWF weather forecast MCP for discovery, validation, and GribStream OAuth queries.

https://gribstream.com/
Hosted MCP endpoint:
https://gribstream.com/mcp
Use GribStream MCP when you want an AI tool to:
/timeseries request for values by valid time./runs request to compare forecasts across model runs./timeseries or /runs queries after OAuth authorization.curl command for the GribStream Weather API.The hosted MCP server exposes discovery, selector lookup, request building, and validation tools before OAuth. Live /timeseries and /runs query tools require OAuth. Tool descriptions begin with either NO AUTH / PUBLIC / READ-ONLY or AUTH REQUIRED / DATA QUERY so AI clients can route metadata tasks and live data-query tasks correctly. When a client connects through OAuth, GribStream asks the user to sign in and select an active GribStream API token. MCP access tokens are scoped to that selected API token, and the raw API token is not shown to the MCP client.
Use the hosted endpoint exactly as shown in any MCP client that supports remote Streamable HTTP:
https://gribstream.com/mcp
Do not include trailing punctuation in the URL.
Generic configuration shape:
{
"mcpServers": {
"gribstream": {
"url": "https://gribstream.com/mcp"
}
}
}
LobeHub quick import configuration:
{
"mcpServers": {
"gribstream": {
"type": "http",
"url": "https://gribstream.com/mcp"
}
}
}
Some clients require an explicit transport field:
{
"mcpServers": {
"gribstream": {
"type": "streamable-http",
"url": "https://gribstream.com/mcp"
}
}
}
OAuth is needed for live query tools. Most MCP clients should discover OAuth from the hosted endpoint automatically, either during connector setup or when the client requests authenticated tools. If a client asks for manual OAuth 2.0 fields, use:
Authorization URL: https://gribstream.com/authorize
Token URL: https://gribstream.com/token
Client ID: gribstream-mcp-public
Client Secret: leave empty; do not enter a value
Scopes: leave empty
Resource or audience, if requested: https://gribstream.com/mcp
OAuth discovery endpoints:
https://gribstream.com/.well-known/oauth-protected-resource/mcp
https://gribstream.com/.well-known/oauth-authorization-server
The OAuth client is public and uses PKCE with token_endpoint_auth_method set to none. Native desktop clients may use loopback redirect URIs such as http://localhost:{port}/..., http://127.0.0.1:{port}/..., or http://[::1]:{port}/.... A setup form that requires a non-empty client secret is asking for a confidential-client flow and is not compatible with this public MCP OAuth flow.
LobeHub and other MCP crawlers may call MCP tools "skills". The live GribStream MCP server exposes the following skills/tools, prompts, and resources.
Public read-only skills/tools are visible before OAuth. OAuth live query skills/tools may be hidden from tools/list until the client completes OAuth or sends a valid Authorization: Bearer token.
Authenticated live query tools support CSV, JSON, NDJSON, and Parquet results. Small CSV, JSON, and NDJSON results can be returned inline. Set delivery=url for dense grids or large results to receive a short-lived signed HTTPS resource_link to the complete file instead.
max_bytes limit applies only to inline MCP results. URL artifacts use a separate server-configured size limit, so omit max_bytes when using delivery=url.delivery=url. Do not install a dependency or write a Parquet parser solely for one result.structuredContent includes metadata such as content_type, rows, bytes, columns, schema, delivery, cache_hit, signed_url_expires_at, and suggested_filename when applicable.request_hash, response_hash, and result_hash. Use suggested_filename when saving multiple results so repeated requests or comparisons do not overwrite earlier files.forecasted_time for /timeseries, and by forecasted_at plus forecasted_time for /runs, before plotting or comparing time series.https://gribstream.com/https://gribstream.com/mcphttps://gribstream.com/mcphttps://gribstream.com/gribstream_small.pnghttps://gribstream.com/docs/openapi.yamlhttps://gribstream.com/aihttps://gribstream.com/app/dashboardAfter connecting GribStream MCP to an AI tool, ask:
Use GribStream MCP to build a GFS 2m temperature timeseries request for Houston for tomorrow at 12:00 UTC. Validate the request and return a runnable curl command.
If your client has completed OAuth, you can also ask it to run the query:
Use GribStream MCP to run a GFS 2m temperature timeseries query for Houston for tomorrow at 12:00 UTC and return CSV.
For a dense-grid visualization:
Using GribStream, plot the latest available ICON-D2 2 metre temperature forecast over Germany at 0.025 degree resolution as a beautiful PNG.
Or:
Use GribStream MCP to find the best dataset for short-range precipitation forecasts in the continental United States. Explain the tradeoffs and build a validated example request.
