WHAT IT DOES

What cancel_job_tool does on Qiskit IBM Transpiler MCP Server

AI agents call cancel_job_tool to permanently remove resources in Qiskit IBM Transpiler MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why cancel_job_tool is rated Critical

Cancelling a job is an irreversible action — once a quantum job submitted to IBM's infrastructure is cancelled, it cannot be restarted or recovered. This constitutes an irreversible termination of an operation, fitting the Destructive category. Severity is high because cancelling a running quantum job wastes allocated compute resources and may disrupt workflows that depend on its results.

cancel_job_tool Hidden

cancel_job_tool is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
