WHAT IT DOES

What deploy-changes does on Stage0 Authorization MCP Server

AI agents invoke deploy-changes to trigger actions in Stage0 Authorization MCP Server. 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.
