os_drag · OScribe MCP: Risk & Policy

WHAT IT DOES

What os_drag does on OScribe

AI agents invoke os_drag to trigger actions in OScribe. 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 os_drag needs a policy

This tool executes UI automation actions (drag-and-drop) that can have wide-ranging side effects depending on what is being dragged. Moving files could displace or overwrite data, reordering items modifies application state, and resizing windows alters UI configuration. It is an Execute-category tool because its effects depend entirely on what arguments are passed and what is being interacted with on screen.

From the tool's definition 'Perform a drag-and-drop operation: moves to start position, holds mouse button, smoothly drags to destination, then releases. Use this for moving files, reordering items, resizing windows, or any UI interaction requiring drag-and-drop.'

Verdict

os_drag Rate-limited

os_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.

How do I enforce a policy on os_drag? +

Register the OScribe MCP server in PolicyLayer and add a rule for os_drag: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches OScribe. Nothing to install.

What risk level is os_drag? +

os_drag is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit os_drag? +

Yes. Add a rate_limit block to the os_drag rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
