- Server: KiCAD-MCP-Server (`mixelpixx/kicad-mcp-server`) — https://policylayer.com/tools/mixelpixx-kicad-mcp-server.md
- Homepage: https://github.com/mixelpixx/KiCAD-MCP-Server

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "place_component_array",
    "arguments": {}
  }
}
```

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches KiCAD-MCP-Server:

```json
