AI agents call nasa_gibs to retrieve information from Nasa without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and serves satellite imagery data. It has no side effects, does not execute code or commands, does not modify or delete data, and does not involve financial transactions. This is a straightforward read operation that queries and returns publicly available NASA imagery data.

Register the Nasa MCP server in PolicyLayer and add a rule for nasa_gibs: 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 Nasa. Nothing to install.
nasa_gibs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the nasa_gibs 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.
Set action: deny in the PolicyLayer policy for nasa_gibs. 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.
