How do I install the noaa mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `MCP_TRANSPORT_TYPE`, `MCP_LOG_LEVEL`, `NOAA_CDO_TOKEN`, `MCP_HTTP_ENDPOINT_PATH`, `MCP_PUBLIC_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Noaa MCP Server?

Search NOAA CDO stations and datasets, fetch historical weather observations.

The short version

Declarative tool definitions — single file per tool, framework handles registration and validation
Unified error handling across all tools
Pluggable auth (none, jwt, oauth)
Swappable storage backends: in-memory, filesystem, Supabase, Cloudflare KV/R2/D1
Structured logging with optional OpenTelemetry tracing
Runs locally (stdio/HTTP) or on Cloudflare Workers from the same codebase

What it needs from you

Bun v1.3.0 or higher (or Node.js ≥24.0.0). - A free NOAA CDO API token — required for all requests.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.

noaa_climate_list_datasets	List available CDO datasets with IDs, names, and temporal coverage
noaa_climate_list_data_categories	List data category groups (Temperature, Precipitation, Wind, etc.)
noaa_climate_list_data_types	List specific measurement labels (TMAX, TMIN, PRCP, SNOW, etc.) by dataset or category
noaa_climate_find_locations	Search geographic locations by category (states, cities, counties, zip codes, climate regions)
noaa_climate_find_stations	Search weather stations by location, bounding box, dataset, and data type
noaa_climate_get_station	Fetch full metadata for a single station by ID
noaa_climate_fetch_data	Fetch historical observation records for a dataset and date range
