submit_task · Unlimited MCP: Risk & Policy

WHAT IT DOES

What submit_task does on Unlimited

AI agents invoke submit_task to trigger actions in Unlimited. 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 IT NEEDS A POLICY

Why submit_task needs a policy

The server description clearly indicates this MCP server submits tasks to background agents that perform coding and sysops work. 'submit_task' likely submits such a task for execution. This falls under Execute as it triggers external operations. The description is empty, lowering confidence, but sibling tools like 'add_queue', 'await_job', 'cancel_job' strongly suggest a job/task execution pipeline.

From the tool's definition Tool name 'submit_task' combined with server description mentioning 'delegates coding and sysops work to cheaper agents via durable background queues, with git worktree isolation, safety policies'

Verdict

submit_task Rate-limited

submit_task 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.
