THE RISK

Why save_project needs a policy

This tool creates or updates a project file, which is a reversible write operation. It does not delete data (ruling out Destructive), execute arbitrary commands (ruling out Execute), or involve financial transactions.

From the tool's definition Tool name 'save_project' and description explicitly state it 'Save[s] the current CLO3D project as a .zprj file' — a persistence operation that modifies/commits the project state to storage.

Documented attack patterns abuse exactly the kind of access save_project gives an agent:

POLICY

How to control save_project

PolicyLayer is an MCP gateway — it sits between your AI agents and CLO3D MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for save_project:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "save_project": {
      "limits": [
        {
          "counter": "save_project_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

save_project 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.

Create a free account and register CLO3D MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about save_project

What does the save_project tool do? +

Save the current CLO3D project as a .zprj file. It is categorised as a Write tool in the CLO3D 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 save_project? +

Register the CLO3D MCP Server MCP server in PolicyLayer and add a rule for save_project: 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 CLO3D MCP Server. Nothing to install.

What risk level is save_project? +

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

Can I rate-limit save_project? +

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

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

save_project is provided by the CLO3D MCP Server MCP server (ubani-studio/clo3d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every CLO3D MCP Server tool call.

Start from CLO3D MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
