WHAT IT DOES

What import_3d_model does on KiCAD-MCP-Server

AI agents use import_3d_model 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 import_3d_model is rated Medium

This tool imports external 3D model files into a KiCAD project, modifying the project state by adding new resources. This is a write operation because it creates/adds project data reversibly. It is not destructive (files are added, not removed), not execute (no arbitrary code or commands), and not financial.

From the tool's definition Tool performs 'Copy a 3D model file' operation, which creates or adds data to the KiCAD project. The action is reversible (the file can be removed or replaced), and no data is deleted or overwritten.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs import_3d_model 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 import_3d_model, this is the rule to start with:

import_3d_model Rate-limited

import_3d_model 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 import_3d_model call is checked against it from then on.

FAQ

Questions about import_3d_model

What does the import_3d_model tool do? +

Copy a 3D model file (.step/.stp/.wrl/.x3d/.iges) into the project. 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 import_3d_model? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for import_3d_model: 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 import_3d_model? +

import_3d_model is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit import_3d_model? +

Yes. Add a rate_limit block to the import_3d_model 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 import_3d_model completely? +

Set action: deny in the PolicyLayer policy for import_3d_model. 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 import_3d_model? +

import_3d_model 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.
