storybloq_unregister_subprocess

Unregister a subprocess after it completes. Idempotent -- no error if the PID was already unregistered. Relaxed validation: works even on expired/terminal sessions to allow cleanup.

How to control storybloq_unregister_subprocess ↓

AI agents use storybloq_unregister_subprocess to create or update resources in Storybloq — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Storybloq environment.

Medium Risk

This tool modifies tracked subprocess state by removing entries from a registry, which is a reversible write operation. It does not execute code (no Execute), delete user data (no Destructive), move money (no Financial), or perform arbitrary operations (no Execute). The idempotent and cleanup-focused nature suggests it is a bookkeeping operation.

From the tool's definition Tool name includes 'unregister', and description states it removes/unregisters a subprocess from the system's tracking.

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

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "storybloq_unregister_subprocess": {
      "limits": [
        {
          "counter": "storybloq_unregister_subprocess_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

storybloq_unregister_subprocess stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Storybloq — 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.
