THE RISK

Why list_jobs needs a policy

This tool retrieves and displays information about existing background jobs. It does not create, modify, delete, or execute any operations—it simply enumerates and filters job metadata. The optional status filter is a read parameter, not a modification. This is a low-severity read operation with minimal blast radius.

From the tool's definition Tool name 'list_jobs' and description 'List all background jobs with optional status filter' indicate a query/retrieval operation with no side effects. The verb 'list' and the filtering capability are characteristic of read-only operations.

POLICY

How to control list_jobs

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_jobs": {}
  }
}

list_jobs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about list_jobs

What does the list_jobs tool do? +

List all background jobs with optional status filter. It is categorised as a Read tool in the Sktime MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_jobs? +

Register the Sktime MCP server in PolicyLayer and add a rule for list_jobs: 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 Sktime. Nothing to install.

What risk level is list_jobs? +

list_jobs is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_jobs? +

Yes. Add a rate_limit block to the list_jobs 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 list_jobs completely? +

Set action: deny in the PolicyLayer policy for list_jobs. 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 list_jobs? +

list_jobs is provided by the Sktime MCP server (sktime/sktime-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Sktime tool call.

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