vfx_rotating_cube · vidMagik- MCP: Risk & Policy

WHAT IT DOES

What vfx_rotating_cube does on vidMagik-mcp

AI agents invoke vfx_rotating_cube to trigger actions in vidMagik-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 vfx_rotating_cube needs a policy

This tool executes a video processing operation (3D cube rotation effect) that transforms video frames. It doesn't read raw data, write persistent files by itself, or perform destructive/financial operations. It runs a rendering/compositing computation whose output depends on the input arguments, placing it in the Execute category.

From the tool's definition 'Simulates a 3D rotating cube effect with the video mapped to its faces' — applies a computational video transformation/effect using MoviePy

Verdict

vfx_rotating_cube Rate-limited

vfx_rotating_cube 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.

FAQ

Questions about vfx_rotating_cube

What does the vfx_rotating_cube tool do? +

Simulates a 3D rotating cube effect with the video mapped to its faces. It is categorised as a Execute tool in the vidMagik-mcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on vfx_rotating_cube? +

Register the vidMagik- MCP server in PolicyLayer and add a rule for vfx_rotating_cube: 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 vidMagik-mcp. Nothing to install.

What risk level is vfx_rotating_cube? +

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

Can I rate-limit vfx_rotating_cube? +

Yes. Add a rate_limit block to the vfx_rotating_cube 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.

How do I block vfx_rotating_cube completely? +

Set action: deny in the PolicyLayer policy for vfx_rotating_cube. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides vfx_rotating_cube? +

vfx_rotating_cube is provided by the vidMagik- MCP server (vizionik25/vidmagik-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
