WHAT IT DOES

What edit_footprint_pad does on KiCAD-MCP-Server

AI agents use edit_footprint_pad 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 edit_footprint_pad is rated Medium

This tool modifies footprint pad parameters in KiCAD design files, which are reversible changes. While modifications to PCB design data can impact manufacturing and assembly, the changes are not destructive (data is not deleted/purged) and do not execute arbitrary code or affect financial systems. Classified as Write rather than Execute because it modifies structured data fields rather than running code/commands.

From the tool's definition Tool performs 'Edit an existing pad' operation on .kicad_mod footprint files. The verb 'edit' indicates modification of existing data structures (pad properties, position, size, shape, etc.) rather than creation from scratch or deletion.

RECOMMENDED RULE

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

edit_footprint_pad Rate-limited

edit_footprint_pad 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.
