Why enrich_datasheets needs a policy

This tool modifies an existing KiCAD schematic file by adding/updating Datasheet URL properties in component symbols. It creates or updates data in a file, which is a reversible write operation (the schematic can be restored). No code execution, deletion, or financial transaction is involved.

POLICY

How to control enrich_datasheets

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 enrich_datasheets:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "enrich_datasheets": {
      "limits": [
        {
          "counter": "enrich_datasheets_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

enrich_datasheets stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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 enrich_datasheets

What does the enrich_datasheets tool do? +

Fill in missing Datasheet URLs in a KiCAD schematic using LCSC part numbers. For every placed symbol that has: • (property. It is categorised as a Write tool in the KiCAD-MCP-Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on enrich_datasheets? +

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

enrich_datasheets is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit enrich_datasheets? +

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

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

enrich_datasheets 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.
