WHAT IT DOES

What plugin_load_to_client does on Overlord MCP Server

AI agents invoke plugin_load_to_client to trigger actions in Overlord 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 plugin_load_to_client needs a policy

Loading a plugin onto a remote client/agent executes an operation on an external system, deploying code or functionality to a live C2 agent. This is an Execute-category action with high severity because it pushes potentially arbitrary plugin code to a remote endpoint, which could alter behavior, open attack surfaces, or be misused by an AI agent to deploy malicious plugins to compromised clients.
