NASA Earthdata MCP
io.github.nasa/earthdata-mcp · 1.0.0
Discover, verify, and access NASA Earth science datasets via the Common Metadata Repository (CMR)
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 35 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |
| Latest connection test reached it | 20 of 20 |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 7 tools.

The tools it lists (7, as of 8 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
get_citationsDiscover 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
get_collectionsSearch 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_resolutio
get_granulesSearch 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 forma
get_keywordsDiscover 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)
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
io.github.nasa/earthdata-mcp, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
