retry_job_tool · MCP Gitlab MCP: Risk & Policy

WHAT IT DOES

What retry_job_tool does on MCP Gitlab

AI agents invoke retry_job_tool to trigger actions in MCP Gitlab. 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 retry_job_tool needs a policy

Retrying a CI/CD job triggers execution of pipeline jobs again, which runs code and external operations. This is an Execute-category action as it re-runs build/test/deploy scripts. Severity is medium because misuse could cause unintended deployments or resource consumption, but effects are generally reversible and scoped to the CI/CD system.

retry_job_tool Rate-limited

retry_job_tool 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.
