NASA Earthdata MCP

Discover citation records directly associated with a collection, or look up a citation by identifier (e.g. DOI). Use this tool to evaluate citation relevance for a collection. Key fields in each returned item: - concept_id: CMR citation concept ID - name: The title or name of the citation - identifier: The primary DOI or identifier - abstract: Abstract text - citation_metadata: Nested metadata including Year, Publisher, and Author list

Search NASA CMR collections and return up to 10 lightweight normalized results. Key return fields in each item: - concept_id: CMR collection concept ID - native_id: native ID of the collection record - revision_id: revision ID of the collection metadata - provider_id: provider ID of the collection - short_name: collection short name - entry_title: collection title - time_start / time_end: temporal coverage bounds - processing_level_id: processing level (e.g., L3, L4) - doi: digital object identifier - collection_data_type: data type (e.g., SCIENCE_QUALITY, NEAR_REAL_TIME) - temporal_resolution / spatial_resolution: extracted resolution strings - related_urls: links to landing pages, documentation, and tools Unfiltered searches are supported when you need broad exploration. IMPORTANT — r

Search NASA CMR granules for a specific parent collection and return up to 10 lightweight normalized results. Key return fields in each item: - concept_id: CMR granule concept ID - native_id: native ID of the granule record - revision_id: revision ID of the granule metadata - provider_id: provider ID of the granule - granule_ur: primary granule identifier - time_start / time_end: temporal coverage bounds - access_urls: actionable data access URLs - cloud_cover: cloud cover percentage - day_night_flag: DAY, NIGHT, BOTH, or UNSPECIFIED - size_mb: file size in megabytes - data_format: file format (e.g., NetCDF-4, GeoTIFF) - bounding_box: [West, South, East, North] Minimum Bounding Rectangle (MBR) footprint. Note: for swath data or irregular polygons, this bounding box fully encloses the data

Discover official Earthdata vocabulary (like 'ATMOSPHERIC WATER VAPOR') directly from NASA's Keyword Management System (KMS). Use this to find the exact preferred labels to construct successful get_collections searches. Key fields in each returned item: - prefLabel: The preferred label to use in searches - uuid: The KMS concept UUID - definition: Context and expanded acronyms - scheme: The vocabulary scheme (e.g. sciencekeywords, platforms)

Search NASA CMR services for a specific parent collection and return all associated normalized UMM-S records. Key fields in each returned item: - concept_id: CMR service concept ID - native_id: native ID of the service record - revision_id: revision ID of the service metadata - provider_id: provider ID of the service - name: service name - type: service type (e.g., OPeNDAP, WCS, Harmony, WMS, WMTS, ESI, EGI - No Processing) - version: service version string - description: human-readable service description - url: Primary endpoint URL information - service_options: supported output formats, projections, subset types, and interpolation methods - operation_metadata: operation names (e.g., GetCapabilities, GetMap) and distributed computing platform Key parameters: - collection_concept_id: re

Search NASA CMR tools for a specific parent collection and return all associated normalized UMM-T records. Key fields in each returned item: - concept_id: CMR tool concept ID - native_id: native ID of the tool record - revision_id: revision ID of the tool metadata - provider_id: provider ID of the tool - name: tool name - type: tool type (e.g., Downloadable Tool, Web User Interface, Web Portal, Model) - version: tool version string - description: human-readable tool description - url: Primary URL for directly accessing the tool - supported_input_formats: file formats the tool can read (e.g., HDF5, NETCDF-4, GeoTIFF) - supported_output_formats: file formats the tool can produce - supported_operating_systems: OS compatibility (name and version) - supported_browsers: browser compatibility (n

Discover scientific variables and measurements associated with a collection, or look up variables by keyword. Use this tool to understand dataset variables, dimensions, and data processing parameters (such as scale, offset, and fill values) before downloading or analyzing data. Key fields in each returned item: - concept_id: CMR variable concept ID - name: Variable short name - long_name: Variable long name - definition: Variable definition - data_type: Data type of the variable - units: Units of measurement - scale: Scale factor - offset: Offset value - fill_values: Values indicating missing or invalid data - valid_ranges: Valid data ranges - dimensions: Variable dimensions
