WHAT IT DOES

What suggest_placement does on KiCAD-MCP-Server

AI agents use suggest_placement 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 suggest_placement is rated Medium

This tool modifies the placement (position/orientation) of PCB components reversibly. While it automates layout suggestions rather than destructive changes, it alters the PCB design state. It does not execute arbitrary code or delete data, so it falls under Write rather than Execute or Destructive.

From the tool's definition The tool 'Propose an optimized PCB footprint placement' and 'pulls connected parts together' indicates modification of component placement data on the PCB.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

suggest_placement Rate-limited

suggest_placement 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.

FAQ

Questions about suggest_placement

What does the suggest_placement tool do? +

Propose an optimized PCB footprint placement that shortens net length, orients parts toward their partners, and removes courtyard overlaps. Force-directed clustering pulls connected parts together (a converter. 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 suggest_placement? +

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

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

Can I rate-limit suggest_placement? +

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

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

suggest_placement 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.
