NASA CMR (Common Metadata Repository)

CMR-MCP provides a bridge between AI assistants and NASA's Common Metadata Repository (CMR) through the Earthaccess library, enabling search and retrieval of NASA Earth science datasets. Developed by PO.DAAC, this server implementation exposes a single tool that allows querying datasets by date range, DAAC provider, and keywords, returning structured information including concept IDs, descriptions, and shortnames. The server is particularly valuable for researchers and data scientists who need to discover and access NASA's extensive catalog of Earth observation data without leaving their AI assistant interface.
