stopAnimation · Maige 3d MCP: Risk & Policy

WHAT IT DOES

What stopAnimation does on Maige 3d

AI agents invoke stopAnimation to trigger actions in Maige 3d. 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 stopAnimation needs a policy

While stopping an animation is reversible (another animation can be started), it is an action that executes external operations whose effects depend on which object and animation context is provided. This fits Execute rather than Write because it is triggering a behavioral change in a running system rather than creating or modifying persistent data.

From the tool's definition Tool name is 'stopAnimation' and description states it will 'Stop any running animation on an object.' This directly triggers an action that modifies the state of a 3D scene by halting an ongoing process.

Verdict

stopAnimation Rate-limited

stopAnimation 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Maige 3d, so you can run agents against it safely.

FAQ

Questions about stopAnimation

What does the stopAnimation tool do? +

Stop any running animation on an object. It is categorised as a Execute tool in the Maige 3d MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on stopAnimation? +

Register the Maige 3d MCP server in PolicyLayer and add a rule for stopAnimation: 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 Maige 3d. Nothing to install.

What risk level is stopAnimation? +

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

Can I rate-limit stopAnimation? +

Yes. Add a rate_limit block to the stopAnimation 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 stopAnimation completely? +

Set action: deny in the PolicyLayer policy for stopAnimation. 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 stopAnimation? +

stopAnimation is provided by the Maige 3d MCP server (m-ai-gexr/mcp-webgpu). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
