addBehavior · Maige 3d MCP: Risk & Policy

WHAT IT DOES

What addBehavior does on Maige 3d

AI agents invoke addBehavior 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 addBehavior needs a policy

This tool attaches ongoing executable logic (frame-tick behavior) to a 3D object, meaning it runs code continuously on every frame render. This constitutes code execution with persistent effects on the scene. Misuse could inject malicious or resource-intensive behavior loops affecting the live 3D environment repeatedly.

Verdict

addBehavior Rate-limited

addBehavior 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 addBehavior

What does the addBehavior tool do? +

Attach a continuous frame-tick behavior to 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 addBehavior? +

Register the Maige 3d MCP server in PolicyLayer and add a rule for addBehavior: 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 addBehavior? +

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

Can I rate-limit addBehavior? +

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

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

addBehavior 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.
