actions_trigger · Git Steer MCP: Risk & Policy

WHAT IT DOES

What actions_trigger does on Git Steer

AI agents invoke actions_trigger to trigger actions in Git Steer. 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 actions_trigger needs a policy

GitHub Actions workflows execute arbitrary code in the repository context, potentially building, deploying, or modifying systems. Triggering workflows is an Execute action because the actual effects depend on the workflow's implementation and arguments.

From the tool's definition Tool explicitly performs 'trigger a workflow', which executes GitHub Actions — external code execution with real-world side effects on repositories and infrastructure.

Verdict

actions_trigger Rate-limited

actions_trigger 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.
