ui_right_click · UI Bridge MCP: Risk & Policy

WHAT IT DOES

What ui_right_click does on UI Bridge MCP

AI agents invoke ui_right_click to trigger actions in UI Bridge MCP. 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 ui_right_click needs a policy

Right-clicking triggers a UI interaction/action (context menu, event handlers) on an element. This is an external operation that executes a UI event, which may have side effects depending on the context menu actions invoked. It falls under Execute as it triggers external UI operations rather than simply reading data.
