What run_job does on Databricks MCP Server

AI agents invoke run_job to trigger actions in Databricks 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.

High Risk

Why run_job needs a policy

This tool triggers external operations (Databricks job execution) whose side effects are determined by the job configuration and supplied arguments. While not immediately destructive, a misused job_id or malicious parameters could cause significant data processing, resource consumption, or unintended transformations.

From the tool's definition Tool name 'run_job' combined with description 'Run a Databricks job' indicates execution of a job with specified parameters.

How to control run_job

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

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

run_job 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 Databricks 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.
