get_mars_photos_by_date
AI agents call get_mars_photos_by_date 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 Mars rover photos filtered by date—a read-only query operation with no side effects. It follows the same pattern as related tools on the server. Even if misused by an AI agent, it cannot create, modify, or delete data, only query public NASA datasets. The worst-case outcome is information disclosure of already-public imagery.
From the tool's definition Tool name 'get_mars_photos_by_date' indicates data retrieval. Sibling tools like 'get_latest_mars_photos', 'get_apod', and 'lookup_asteroid' are all read-only query operations.

"tools": {
"get_mars_photos_by_date": {}
