WHAT IT DOES

What batch_download_images does on Copernicus Earth Observation MCP Server

WHY IT NEEDS A POLICY

Why batch_download_images needs a policy

This tool downloads and stores multiple satellite image files to local/server storage concurrently. Downloading writes data to disk and can consume significant storage, bandwidth, and time resources. While not destructive or financial, misuse by an AI agent could trigger massive unintended downloads (hours-long operations, large storage consumption), justifying high severity.
