Clean up downloaded files based on criteria
AI agents call cleanup_downloads to permanently remove resources in Copernicus Earth Observation MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cleaning up files means deleting or purging previously downloaded satellite imagery from local storage. File deletion is generally irreversible. Given that satellite imagery downloads can be large and costly to re-acquire, misuse of this tool could result in significant data loss. The phrase 'based on criteria' suggests it could match and delete multiple files at once, increasing the blast radius.
From the tool's definition 'Clean up downloaded files' — removing files is an irreversible destructive action
Attacks that exploit this kind of access
Clean up downloaded files based on criteria. It is categorised as a Destructive tool in the Copernicus Earth Observation MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Copernicus Earth Observation MCP Server MCP server in PolicyLayer and add a rule for cleanup_downloads: 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 Copernicus Earth Observation MCP Server. Nothing to install.
cleanup_downloads is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the cleanup_downloads 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 cleanup_downloads. 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.
cleanup_downloads is provided by the Copernicus Earth Observation MCP Server MCP server (wb1016/copernicus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
