List downloaded Copernicus satellite image files
AI agents call list_downloaded_files to retrieve information from Copernicus Earth Observation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation—listing or querying files in a local downloads directory. It has no side effects, does not modify data, does not execute external commands, and does not involve financial transactions. The blast radius of misuse is minimal; an attacker could only discover what files exist locally, not access their contents, delete them, or trigger external operations.
From the tool's definition Tool name 'list_downloaded_files' and description 'List downloaded Copernicus satellite image files' indicate a retrieval operation that queries and reports on existing downloaded data without modifying, deleting, or executing operations.

list_downloaded_files 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 list_downloaded_files 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.
