WHAT IT DOES

What broadcast_to_cluster does on Cluster Execution MCP Server

AI agents invoke broadcast_to_cluster to trigger actions in Cluster Execution 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.

WHY IT NEEDS A POLICY

Why broadcast_to_cluster needs a policy

The tool name 'broadcast_to_cluster' strongly implies sending commands or messages to all nodes in a distributed cluster simultaneously. Given the server's explicit purpose of cluster-aware command execution, SSH-based remote node management, and parallel execution, broadcasting likely triggers execution across multiple nodes at once.

From the tool's definition Tool name 'broadcast_to_cluster' on a server that 'Enables cluster-aware command execution' with 'parallel execution, remote node management via SSH, and dynamic load balancing'.
