WHAT IT DOES

What download_jlcpcb_database does on KiCAD-MCP-Server

AI agents use download_jlcpcb_database to create or update resources in KiCAD-MCP-Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your KiCAD-MCP-Server environment.

RISK

Why download_jlcpcb_database is rated Medium

This tool downloads external data and writes it to a local SQLite database file. It creates/overwrites a local database (~1.5GB or ~10GB depending on source). It is a Write operation (creating/updating a local file), not Destructive since it's creating new data rather than irreversibly deleting anything, and not Execute since it's a data download/storage operation rather than running arbitrary code or commands.
