scout_drag · Scout MCP: Risk & Policy

WHAT IT DOES

What scout_drag does on Scout

AI agents invoke scout_drag to trigger actions in Scout. 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 scout_drag needs a policy

Dragging elements in a browser can trigger writes, moves, or state changes (e.g., reordering items, moving files, triggering drop events) whose effects depend on the context. This is a browser action that executes an interaction, making Execute the appropriate category. Severity is medium because the blast radius depends on what is being dragged and where.

From the tool's definition 'Drag one element onto another' — triggers a browser interaction (drag-and-drop) that manipulates UI elements and can cause side effects depending on the target application.

Verdict

scout_drag Rate-limited

scout_drag 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.
