WHAT IT DOES

What list_graphics does on KiCAD-MCP-Server

AI agents call list_graphics to retrieve information from KiCAD-MCP-Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_graphics is rated Low

This tool retrieves and enumerates graphical and drawing elements from a PCB design file. It performs a read-only operation that queries the state of existing graphics without creating, modifying, deleting, or executing any operations. The low severity reflects that accessing design metadata poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name is 'list_graphics' and description states it 'List[s] PCB graphic/drawing items such as gr_line, gr_arc, gr_rect, gr_text and dimensions.' The verb 'List' indicates retrieval/query of existing data with no modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_graphics Allowed

list_graphics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_graphics": {}
  }
}

ALLOW ONLY 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 list_graphics call is checked against it from then on.

Can I rate-limit list_graphics? +

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

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

list_graphics 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.
