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

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

## Why async_tool is rated Low

With no description and only a generic name ('async_tool'), there is insufficient information to determine what this tool does. The name alone only suggests it operates asynchronously, but provides no clue about its category or potential impact. Defaulting to 'Other' with very low confidence.

From the tool's own definition: "Tool name is 'async_tool' with an empty description. No information about what the tool does is provided."

## Use case

AI agents call async_tool as a supporting operation in Agent Jail workflows.

## 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": {
    "async_tool": {
      "limits": [
        {
          "counter": "async_tool_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
```
