WHAT IT DOES

What add_component_3d_model does on KiCAD-MCP-Server

AI agents use add_component_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 add_component_3d_model is rated Medium

This tool creates or modifies metadata (3D model attachment) on existing board elements. It is reversible (models can be detached or replaced) and affects only the PCB design file structure, not production or financial systems. It falls under Write category. Severity is medium because misuse could corrupt board designs or add unintended 3D models, but effects are localized to the design file and fully reversible.

From the tool's definition Tool description states 'Attach a 3D model to one or more PLACED footprints on the open board' — this is a create/modify operation that adds or updates 3D model data associated with board components.

RECOMMENDED RULE

The rule that runs add_component_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 add_component_3d_model, this is the rule to start with:

add_component_3d_model Rate-limited

add_component_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.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every add_component_3d_model call is checked against it from then on.

FAQ

Questions about add_component_3d_model

What does the add_component_3d_model tool do? +

Attach a 3D model to one or more PLACED footprints on the open board, live via. 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 add_component_3d_model? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for add_component_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 add_component_3d_model? +

add_component_3d_model is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_component_3d_model? +

Yes. Add a rate_limit block to the add_component_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 add_component_3d_model completely? +

Set action: deny in the PolicyLayer policy for add_component_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 add_component_3d_model? +

add_component_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.
