jenkins_disable_job · Jenkins Http MCP: Risk & Policy

WHAT IT DOES

What jenkins_disable_job does on Jenkins Http

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

WHY IT NEEDS A POLICY

Why jenkins_disable_job needs a policy

Disabling a job modifies its configuration state reversibly—the job can be re-enabled later. This is a Write operation (not Destructive, as no data is deleted or permanently lost) with medium severity because disabling a critical job could disrupt CI/CD pipelines and deployments if an AI agent misuses it, but the action is reversible and does not delete data or commit financial obligations.

From the tool's definition Tool description states 'Disable a job' and requires JENKINS_MCP_ENABLE_WRITES=1, indicating a write operation that modifies job state.
