CMR MCP Server

Example Use Cases

• 1

  Search NASA's CMR for datasets by date range, keywords, or provider (e.g., PO.DAAC).

• 2

  Integrate dataset discovery into conversational workflows via an MCP-compatible client (e.g., Claude Desktop).

• 3

  A local MCP server setup to route LLM retrieval requests to EarthAccess/CMR with configurable invocation via the uv runtime.

Description

This repository implements a Model Context Protocol (MCP) server for NASA Earthdata's Common Metadata Repository (CMR), enabling LLM-based agents to query and retrieve dataset metadata. It integrates with EarthAccess and provides instructions for running the server locally using the uv Python tool and connecting it to agent clients such as Claude Desktop. The README includes configuration examples and usage prompts to help agents perform date- and keyword-based dataset searches.
