create_job_from_notebook

THE RISK

High Risk

This tool creates a scheduled job that will repeatedly execute notebook code. While it involves creation (Write), the primary risk is that it triggers recurring code execution, which could run arbitrary database queries, scripts, or operations on a schedule. The Execute category is more severe and appropriate here due to the execution aspect of scheduled jobs.

From the tool's definition "Create a scheduled job from a notebook" — creates and schedules execution of notebook code

HOW TO CONTROL CREATE_JOB_FROM_NOTEBOOK

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_job_from_notebook": {
      "limits": [
        {
          "counter": "create_job_from_notebook_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_job_from_notebook 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.

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