WHAT IT DOES

What unity_constraint_add does on Unity MCP Server

AI agents use unity_constraint_add to create or update resources in Unity MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unity MCP Server environment.

RISK

Why unity_constraint_add is rated Medium

This tool modifies the animation rig and constraint configuration of GameObjects, which is a reversible write operation. It does not delete data (not Destructive), execute arbitrary code (not Execute), or involve financial transactions (not Financial).

From the tool's definition Tool adds (creates/modifies) animation constraints to GameObjects. The verb 'add' and the action of attaching constraints to game objects constitutes data modification within the Unity scene.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs unity_constraint_add safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_constraint_add, this is the rule to start with:

unity_constraint_add Rate-limited

unity_constraint_add stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Unity MCP Server, apply this rule, and every unity_constraint_add call is checked against it from then on.

FAQ

Questions about unity_constraint_add

What does the unity_constraint_add tool do? +

Add an animation constraint (position, rotation, scale, aim, parent, lookat) to a GameObject with optional source. It is categorised as a Write tool in the Unity MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on unity_constraint_add? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_constraint_add: 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 Unity MCP Server. Nothing to install.

What risk level is unity_constraint_add? +

unity_constraint_add is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit unity_constraint_add? +

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

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

unity_constraint_add is provided by the Unity MCP Server MCP server (anklebreaker-studio/unity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
