- Server: Agent Jail (`idiscoord13-sketch/agent-jail-mcp`) — https://policylayer.com/tools/agent-jail-mcp.md
- Homepage: https://github.com/idiscoord13-sketch/agent-jail-mcp

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

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

## Why custom_name is rated Low

With an empty description and an ambiguous name, it is impossible to determine the tool's behavior or risk. Defaulting to 'Other' with low confidence and low severity since there is no evidence of any impactful action.

From the tool's own definition: "Tool name is 'custom_name' and description is empty, providing no actionable information about what the tool does."

## Use case

AI agents call custom_name 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": {
    "custom_name": {
      "limits": [
        {
          "counter": "custom_name_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
```
