WHAT IT DOES

What export_gerber_single does on KiCAD-MCP-Server

AI agents use export_gerber_single 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_single is rated Medium

The tool generates Gerber files (manufacturing output) from KiCAD design data. This is a reversible write operation—it creates/exports data artifacts but does not delete, execute arbitrary code, move money, or modify the underlying design in an irreversible way. The operation has localized blast radius (generated export files), justifying medium severity.

From the tool's definition Tool name 'export_gerber_single' and description 'Plot the given layers to a SINGLE Gerber file via kicad-cli' indicate file generation/export that creates new output data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs export_gerber_single 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_single, this is the rule to start with:

export_gerber_single Rate-limited

export_gerber_single 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.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every export_gerber_single call is checked against it from then on.
