WHAT IT DOES

What nasa-cmr.datasets.search does on Apibase

AI agents call nasa-cmr.datasets.search to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`bbox`	string	—	Bounding box spatial filter as "west,south,east,north" decimal degrees (e.g. "-180,-90,180,90" for global, "-125,24,-66,50" for continental US). Returns collect
`keyword`	string	—	Free-text keyword to search collection titles, summaries, and metadata (e.g. "sea surface temperature", "MODIS land cover", "global precipitation").
`provider`	string	—	Filter by NASA data center / archive provider ID (e.g. "GES_DISC", "ORNL_DAAC", "LPDAAC_ECS", "PODAAC", "NSIDC_ECS"). Use nasa-cmr.providers.list to discover av
`sort_key`	string	—	Sort order for results: "-score" (relevance, default), "entry_title" / "-entry_title" (alphabetical), "start_date" / "-start_date" (temporal coverage start date
`page_size`	integer	—	Number of collections to return per page (1–20, default 10).
`short_name`	string	—	Exact collection short name identifier (e.g. "MOD13A2", "GPM_3IMERGHHE"). Use when you know the specific dataset short name.
`temporal_end`	string	—	End of temporal coverage filter in ISO 8601 UTC format (e.g. "2023-12-31T23:59:59Z"). Returns collections whose temporal extent overlaps this range.
`temporal_start`	string	—	Start of temporal coverage filter in ISO 8601 UTC format (e.g. "2020-01-01T00:00:00Z"). Returns collections whose temporal extent overlaps this range.
`processing_level`	string	—	NASA data processing level filter (e.g. "1B", "2", "3", "4"). Level 1 = raw/calibrated; Level 2 = geophysical retrievals; Level 3 = gridded; Level 4 = model out

RISK

Why nasa-cmr.datasets.search is rated Low

Tool queries public NASA satellite metadata and returns results only; no side effects, modifications, or external operations triggered.

From the tool's definition Search NASA CMR for Earth science satellite datasets. Filter by keyword, provider, temporal range, spatial bounding box. Returns concept IDs, titles, summaries.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs nasa-cmr.datasets.search safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For nasa-cmr.datasets.search, this is the rule to start with:

nasa-cmr.datasets.search Allowed

nasa-cmr.datasets.search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "nasa-cmr.datasets.search": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every nasa-cmr.datasets.search call is checked against it from then on.

FAQ

Questions about nasa-cmr.datasets.search

What does the nasa-cmr.datasets.search tool do? +

Search NASA Common Metadata Repository (CMR) for Earth science satellite datasets and collections. Filter by keyword, data provider (ORNL_DAAC, GES_DISC, LPDAAC_ECS, PODAAC, NSIDC_ECS), temporal range, spatial bounding box, and processing level. Returns concept IDs, titles, summaries, data centers, temporal coverage, and access flags. CMR indexes 45,000+ collections covering climate, land, atmosphere, ocean, cryosphere, and biosphere from 60+ NASA data archives. Concept IDs from results feed into nasa-cmr.datasets.detail and nasa-cmr.granules.search. Source: NASA CMR — US Gov public domain, no auth required. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.

What parameters does nasa-cmr.datasets.search accept? +

nasa-cmr.datasets.search accepts 9 parameters: bbox, keyword, provider, sort_key, page_size, short_name, temporal_end, temporal_start, processing_level. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on nasa-cmr.datasets.search? +

Register the Apibase MCP server in PolicyLayer and add a rule for nasa-cmr.datasets.search: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apibase. Nothing to install.

What risk level is nasa-cmr.datasets.search? +

nasa-cmr.datasets.search is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit nasa-cmr.datasets.search? +

Yes. Add a rate_limit block to the nasa-cmr.datasets.search rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block nasa-cmr.datasets.search completely? +

Set action: deny in the PolicyLayer policy for nasa-cmr.datasets.search. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides nasa-cmr.datasets.search? +

nasa-cmr.datasets.search is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
