Get all constraints on a GameObject with their type, active state, weight, and source count.
AI agents call unity_constraint_info to retrieve information from Unity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation on existing GameObject constraint data. It retrieves and reports information about constraints without creating, modifying, deleting, or executing any operations. The action is informational and has no side effects on the game state or assets.
From the tool's definition Tool name 'unity_constraint_info' with description 'Get all constraints on a GameObject' - uses 'Get' which indicates data retrieval with no side effects. Returns constraint metadata (type, active state, weight, source count) without modification.
Documented attack patterns abuse exactly the kind of access unity_constraint_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unity_constraint_info:
{
"version": "1",
"default": "deny",
"tools": {
"unity_constraint_info": {}
}
}unity_constraint_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all constraints on a GameObject with their type, active state, weight, and source count. It is categorised as a Read tool in the Unity MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_constraint_info: 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.
unity_constraint_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the unity_constraint_info 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.
Set action: deny in the PolicyLayer policy for unity_constraint_info. 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.
unity_constraint_info 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.
