Why get_jlcpcb_database_stats needs a policy

This tool queries and returns statistics from a local parts database. It performs no creation, modification, deletion, code execution, or financial operations. The action is purely informational retrieval, which is characteristic of Read category tools. The blast radius is minimal since statistics queries cannot harm the underlying system or data.

From the tool's definition Tool name includes 'get_' and description states 'Get statistics about the local JLCPCB parts database' — both indicate retrieval of data without modification or side effects.

POLICY

How to control get_jlcpcb_database_stats

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_jlcpcb_database_stats:

policy.json

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

get_jlcpcb_database_stats 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.

How do I enforce a policy on get_jlcpcb_database_stats? +

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

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

Can I rate-limit get_jlcpcb_database_stats? +

How do I block get_jlcpcb_database_stats completely? +

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

get_jlcpcb_database_stats 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.
