Noaa Cdo Mcp Server

cyanheads/noaa-cdo-mcp-server

Wraps NOAA's Climate Data Online API v2 to search weather stations and pull historical observations going back to 1763. You get seven tools covering the full discovery flow: list datasets (GHCND daily, GSOM monthly, climate normals), find locations by state or zip, search stations by bounding box or data type, and fetch observation records with automatic date range validation. The fetch tool enforces per-dataset limits (one year for daily, ten for monthly) and handles unit conversion since raw GHCND values come as tenths-of-unit integers. Includes resources for dataset metadata and station lookups. Useful when you need programmatic access to temperature, precipitation, wind, or snow data without writing pagination and validation logic yourself.
