WHAT IT DOES

What export_gerber does on KiCAD-MCP-Server

AI agents use export_gerber 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 export_gerber is rated Medium

This tool creates new files (Gerber manufacturing data) in a specified directory, which is a Write operation—data is being produced and stored reversibly. It is not Destructive because exporting doesn't overwrite or irreversibly delete existing data (exports are additive).

From the tool's definition Tool exports PCB Gerber manufacturing files to a directory. Gerber files are generated outputs (creates or writes files to disk).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs export_gerber safely

PolicyLayer is an MCP gateway: it sits between your AI agents and KiCAD-MCP-Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For export_gerber, this is the rule to start with:

export_gerber Rate-limited

export_gerber stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
