WHAT IT DOES

What export_vrml does on KiCAD-MCP-Server

AI agents use export_vrml 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_vrml is rated Medium

This tool creates a new output artifact (VRML file) without altering the source PCB design data. It is a read-based operation that generates derived content, but since it produces a file artifact, it fits Write category rather than Read. The severity is low because the operation is reversible, cannot harm the original design, and has no side effects on the project state.

From the tool's definition Tool is 'export_vrml' which exports PCB as VRML 3D model. Export operations generate output files (write operation), but do not modify the underlying PCB design file itself.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

export_vrml Rate-limited

export_vrml 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_vrml call is checked against it from then on.

FAQ

Questions about export_vrml

What does the export_vrml tool do? +

Export the PCB as a VRML 3D model for use in web viewers or simulation tools. 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_vrml? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for export_vrml: 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_vrml? +

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

Can I rate-limit export_vrml? +

Yes. Add a rate_limit block to the export_vrml 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_vrml completely? +

Set action: deny in the PolicyLayer policy for export_vrml. 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_vrml? +

export_vrml 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.
