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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "c4_export",
    "arguments": {}
  }
}
```

## Why c4_export is rated Medium

The name 'export' typically implies writing or exporting data (a reversible operation), which falls under the Write category. However, without a description, confidence is reduced. If export creates files or serializes data, it modifies state (Write). The medium severity reflects potential for batch data extraction or format conversion that could have downstream effects, though it remains reversible.

From the tool's own definition: "Tool name 'c4_export' suggests exporting data; description is empty, providing no direct evidence of function or side effects."

## Use case

AI agents use c4_export to create or update resources in C4REQBER, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your C4REQBER environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches C4REQBER:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "c4_export": {
      "limits": [
        {
          "counter": "c4_export_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
