## Facts

- Tool: `stop_server`
- Server: Code MCP Server (`agentics-ai/code-mcp`) — https://policylayer.com/tools/agentics-ai-code-mcp.md
- Homepage: https://github.com/agentics-ai/code-mcp
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why stop_server is rated High

This tool executes a command that terminates a server process. While it does not permanently delete data (ruling out Destructive), it does execute an external operation that interrupts running services and could disrupt active operations or workflows. The context of a Code MCP Server with Docker integration suggests this could stop critical infrastructure.

From the tool's own definition: "The tool 'stop_server' performs an operational action to 'stop a running server', which triggers an external operation with immediate effects on system state."

## Use case

AI agents invoke stop_server to trigger actions in Code MCP Server. 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 Code MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "stop_server": {
      "limits": [
        {
          "counter": "stop_server_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
