THE RISK

Low Risk

Why get_schematic_pin_locations needs a policy

This tool retrieves geometric/positional data from an existing schematic without creating, modifying, deleting, or executing any operations. It is purely informational in nature, used to support placement decisions in subsequent operations. The low severity reflects that misuse would only result in incorrect read operations or position data, not destructive or irreversible changes to the design.

From the tool's definition The tool description states it 'Returns the exact x/y coordinates' of schematic component pins. The verb 'Returns' indicates data retrieval with no modification or side effects.

POLICY

How to control get_schematic_pin_locations

PolicyLayer is an MCP gateway — it sits between your AI agents and KiCAD-MCP-Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_schematic_pin_locations:

policy.json

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

get_schematic_pin_locations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register KiCAD-MCP-Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about get_schematic_pin_locations

What does the get_schematic_pin_locations tool do? +

Returns the exact x/y coordinates of every pin on a schematic component. Use this before add_schematic_net_label to place labels correctly on pin endpoints. It is categorised as a Read tool in the KiCAD-MCP-Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_schematic_pin_locations? +

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

get_schematic_pin_locations is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_schematic_pin_locations? +

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

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

get_schematic_pin_locations 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.

Enforce policy on every KiCAD-MCP-Server tool call.

Start from KiCAD-MCP-Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
