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

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

## Why store_data is rated Medium

The name 'store_data' strongly suggests a write operation (creating or storing data). However, the empty description provides no details about what data is stored, where, or whether it could be destructive. Given the sibling tools context (expense tracking, email, user info), this is likely a general-purpose write operation. Confidence is lowered due to the lack of description.

From the tool's own definition: "Tool name 'store_data' implies writing/storing data; description is empty and uninformative."

## Use case

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

## Recommended policy (PolicyLayer)

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

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