project_status

THE RISK

Low Risk

Why project_status needs a policy

The tool retrieves connectivity status information without side effects. It does not create, modify, delete, or execute any operations on the Unity project. This is a straightforward status query, fitting the Read category. The severity is low because even misuse cannot cause harm—it only reports information.

From the tool's definition Tool description states it performs a "simple connectivity test only" with "Check Unity MCP server connection status". This is a read-only operation that queries the status of a connection without modifying, executing, or affecting any Unity project state.

POLICY

How to control project_status

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server for Unity, and nothing reaches the server without passing your rules. This is the rule we recommend for project_status:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "project_status": {}
  }
}

project_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register MCP Server for Unity — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on project_status? +

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

What risk level is project_status? +

Can I rate-limit project_status? +

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

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

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

Enforce policy on every MCP Server for Unity tool call.

Start from MCP Server for Unity, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
