stop_job · UiPath MCP Server MCP: Risk & Policy

WHAT IT DOES

What stop_job does on UiPath MCP Server

AI agents invoke stop_job to trigger actions in UiPath 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.

WHY IT NEEDS A POLICY

Why stop_job needs a policy

Stopping a job is an active intervention in a running process that has immediate operational consequences. While not destructive (the job's data remains), it is definitively Execute category because it triggers external operations and changes system state in ways that depend on the specific argument (job ID).

From the tool's definition Tool name is 'stop_job' with description 'Stop or kill a running UiPath job.' This directly triggers an external operation (stopping an active job in UiPath Orchestrator) whose effects depend on which job argument is provided.

Verdict

stop_job Rate-limited

stop_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.
