## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "add_schematic_net_label",
    "arguments": {}
  }
}
```

## Why add_schematic_net_label is rated Medium

Adding a schematic net label creates or modifies design data in KiCAD (a PCB/circuit design tool) reversibly. The operation can be undone and does not destroy data or execute arbitrary code. It falls clearly into the Write category. Severity is medium because incorrect net labels could cause design errors leading to circuit malfunctions, but the effect is limited to a single schematic element and is reversible.

From the tool's own definition: "Tool name 'add_schematic_net_label' and description 'Add a net label to the schematic' indicate creation of a new schematic element. This is a create/modify operation that adds a net label to circuit design."

## Use case

AI agents use add_schematic_net_label to create or update resources in KiCAD-MCP-Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your KiCAD-MCP-Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches KiCAD-MCP-Server:

```json
