Get APOD entries for a date range.
AI agents call get_apod_date_range 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 or queries APOD (Astronomy Picture of the Day) data for a specified date range. It has no side effects, does not modify data, execute code, delete records, or move money. The operation is a straightforward data retrieval from a public API. Misuse by an AI agent would be limited to excessive API calls or information gathering, which poses minimal security risk.
From the tool's definition Tool name 'get_apod_date_range' and description 'Get APOD entries for a date range' indicate a retrieval operation. APOD (Astronomy Picture of the Day) is a public NASA dataset.
Documented attack patterns abuse exactly the kind of access get_apod_date_range gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nasa, and nothing reaches the server without passing your rules. This is the rule we recommend for get_apod_date_range:
{
"version": "1",
"default": "deny",
"tools": {
"get_apod_date_range": {}
}
}get_apod_date_range is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get APOD entries for a date range. It is categorised as a Read tool in the Nasa MCP Server, which means it retrieves data without modifying state.
Register the Nasa MCP server in PolicyLayer and add a rule for get_apod_date_range: 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.
get_apod_date_range 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 get_apod_date_range 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 get_apod_date_range. 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.
get_apod_date_range is provided by the Nasa MCP server (jezweb/nasa-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nasa, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
