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

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

## Why subscribe is rated Low

With no description provided, the tool's behavior cannot be determined from the available information. The name 'subscribe' could suggest listening to events or messages (a Read-like operation), but given the server context of iTerm2 terminal session management and AI orchestration, it might relate to subscribing to a message bus or event stream.

From the tool's own definition: "Tool name is 'subscribe' with an empty description. No functional details are available to determine what this tool does."

## Use case

AI agents call subscribe as a supporting operation in iTerm MCP workflows.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "subscribe": {
      "limits": [
        {
          "counter": "subscribe_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
```
