THE RISK

Low Risk

Why find_component_connections needs a policy

Based on the tool name and context of a KiCad analysis server, 'find_component_connections' most likely retrieves or queries connection data between components in a circuit design. This is a read-only operation with no side effects. Empty description lowers confidence slightly, but the server's stated purpose (analyze, list, visualize) and sibling tools all support read-only classification.

From the tool's definition Tool name 'find_component_connections' indicates querying/analyzing circuit relationships. Description is empty, but sibling tools (analyze_schematic_connections, extract_project_netlist, extract_schematic_netlist) on this KiCad server are all read-only data…

POLICY

How to control find_component_connections

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 find_component_connections:

policy.json

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

find_component_connections 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 find_component_connections

What does the find_component_connections tool do? +

find_component_connections. 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 find_component_connections? +

Register the KiCad MCP Server MCP server in PolicyLayer and add a rule for find_component_connections: 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 find_component_connections? +

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

Can I rate-limit find_component_connections? +

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

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

find_component_connections is provided by the KiCad MCP Server MCP server (lamaalrajih/kicad-mcp). 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.
