WHAT IT DOES

What export_3d does on KiCAD-MCP-Server

AI agents use export_3d 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_3d is rated Medium

The export_3d tool creates new 3D model files from existing PCB data. This is a Write operation because it generates/creates new data (the exported 3D files), but the action is reversible and has no side effects on the PCB design itself or critical data. It does not execute arbitrary code, delete data, or modify financial state.

From the tool's definition Tool performs 'export' operation which creates/generates output files in standard 3D formats (STEP, STL, VRML, OBJ). The description indicates this generates new data artifacts without modifying the source PCB design.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs export_3d 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_3d, this is the rule to start with:

export_3d Rate-limited

export_3d 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every export_3d call is checked against it from then on.

FAQ

Questions about export_3d

What does the export_3d tool do? +

Export the PCB as a 3D model (STEP, STL, VRML or OBJ) including optional copper, solder mask, silkscreen and component 3D models. It is categorised as a Write tool in the KiCAD-MCP-Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on export_3d? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for export_3d: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches KiCAD-MCP-Server. Nothing to install.

What risk level is export_3d? +

export_3d is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit export_3d? +

Yes. Add a rate_limit block to the export_3d rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block export_3d completely? +

Set action: deny in the PolicyLayer policy for export_3d. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides export_3d? +

export_3d is provided by the KiCAD-MCP-Server MCP server (mixelpixx/kicad-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
