Data offered docs-verified: NASA Earth science dataset (collection) discovery via CMR · granule (data file) search and data availability checks · NASA KMS scientific keyword vocabulary · data access services (OPeNDAP, Harmony, WMS/WMTS) · web portals and downloadable tools (e.g. Giovanni, Worldview, Panoply) · citation records (publications, DOIs) · scientific variables and measurements (scale, offset, fill values)
Coverage llm-inferred: Global
Formats docs-verified: MCP streamable HTTP
Access docs-verified: Remote hosted MCP endpoint at https://cmr.earthdata.nasa.gov/mcp/v1. No authentication for the MCP endpoint is documented, and ENTRY lists auth and licence as null. Data authentication and download are handled through the earthaccess Python library.

Use cases llm-inferred: Discover candidate NASA satellite precipitation or elevation datasets for supplementary catchment context · Check granule availability over a site and date range before scoping a remote sensing data request · Find OPeNDAP or WMS access endpoints for environmental baseline layers · Locate citable publications and DOIs for a dataset used in a technical report
Audience llm-inferred: GIS analysts · hydrologists · environmental consultants · remote sensing specialists

Constraints llm-inferred: Global NASA datasets, with no UK-specific coverage stated; coverage must be verified per region · Collections can declare global coverage despite data gaps, so granule checks are needed · The discover_data tool and its ingestion pipeline are legacy and being deprecated · Clients should allow a 60000 ms timeout for complex spatial or temporal queries · Downloads require the earthaccess library and its authentication · No rate limits or service-level commitments are documented
