WHAT IT DOES

What jenkins_enable_job does on Mcp Jenkins

AI agents use jenkins_enable_job to create or update resources in Mcp Jenkins — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Jenkins environment.

WHY IT NEEDS A POLICY

Why jenkins_enable_job needs a policy

Enabling a disabled Jenkins job restores it to an active state, allowing it to run builds. This is a reversible state change (it can be disabled again), so it falls under Write rather than Destructive or Execute. Misuse could cause unintended builds to run, giving it medium severity.
