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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "grok-reply",
    "arguments": {}

## Why grok-reply is rated High

This tool executes operations against the Grok service (a third-party LLM) by continuing a session. While it doesn't directly run shell commands or arbitrary code locally, it triggers external execution of AI model inference which can produce arbitrary outputs and side effects depending on the prior session context and new prompts. The in-memory session state means effects persist across calls.

From the tool's own definition: "Tool continues an existing Grok session, implying execution of code or queries in an external model service. The session is in-memory and persists state across invocations, indicating stateful execution of generative AI model outputs."

## Use case

AI agents invoke grok-reply to trigger actions in Deliberation. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "grok-reply": {
      "limits": [
        {
          "counter": "grok-reply_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
