AI agents call nasa_apod to retrieve information from UnClick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This tool retrieves publicly available astronomy imagery from NASA's API. It performs a read-only query operation with no capability to modify, execute, delete, or commit financial transactions. The data retrieved is static and non-sensitive. Severity is low due to minimal blast radius if misused by an AI agent—at worst, excessive requests might hit rate limits.
From the tool's definition Tool name 'nasa_apod' and description 'Get NASA Astronomy Picture of the Day' indicate a retrieval operation with no side effects. The verb 'Get' confirms data is being queried/fetched.

nasa_apod accepts 3 parameters: date, count, api_key. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for nasa_apod: 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 UnClick. Nothing to install.
nasa_apod 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_apod 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_apod. 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.
nasa_apod is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
