WHAT IT DOES

What place_component_array does on KiCAD-MCP-Server

AI agents use place_component_array 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 place_component_array is rated Medium

The tool creates new component placements on a PCB, which is a reversible write operation (components can be moved or deleted). It does not execute arbitrary code, delete data irreversibly, move money, or merely read existing data. The severity is medium because misuse could result in a malformed PCB design requiring rework, but the effects are not catastrophic or irreversible at the design level.

From the tool's definition Tool description states 'Place a rectangular grid array of identical components on the PCB' — this is a creation/modification action that adds components to the PCB design.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

place_component_array Rate-limited

place_component_array 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 place_component_array call is checked against it from then on.

FAQ

Questions about place_component_array

What does the place_component_array tool do? +

Place a rectangular grid array of identical components on the PCB with configurable row/column spacing. 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 place_component_array? +

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

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

Can I rate-limit place_component_array? +

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

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

place_component_array 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.
