What restart_stack does on Komodo MCP Server

AI agents invoke restart_stack to trigger actions in Komodo 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.

Why restart_stack needs a policy

Restarting a stack executes a command that causes running infrastructure to be interrupted and restarted. This is an Execute action because it triggers external infrastructure operations whose effects depend on which stack is targeted. It is not Destructive (no irreversible deletion), Write (not creating/modifying data reversibly), or Financial.

From the tool's definition Tool name 'restart_stack' and description 'Reinicia un stack' (restarts a stack) indicate execution of infrastructure operations that trigger external state changes.

Documented attack patterns abuse exactly the kind of access restart_stack gives an agent:

How to control restart_stack

PolicyLayer is an MCP gateway — it sits between your AI agents and Komodo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for restart_stack:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "restart_stack": {
      "limits": [
        {
          "counter": "restart_stack_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

restart_stack stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Komodo MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on restart_stack? +

Register the Komodo MCP Server MCP server in PolicyLayer and add a rule for restart_stack: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Komodo MCP Server. Nothing to install.

What risk level is restart_stack? +

restart_stack is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit restart_stack? +

Yes. Add a rate_limit block to the restart_stack rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block restart_stack completely? +

Set action: deny in the PolicyLayer policy for restart_stack. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides restart_stack? +

restart_stack is provided by the Komodo MCP Server MCP server (nonetss/komodo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Komodo MCP Server tool call.

Start from Komodo MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
