THE RISK

Medium Risk

Why meshy_repair_printability needs a policy

Repairing a 3D model modifies it, which is a Write operation. It creates a new repaired version or overwrites defects, but is generally reversible (original may still exist). No code execution, deletion, or financial transaction is implied. Confidence is moderate because the description is very brief and it's unclear whether the original is overwritten or a new model is created.

From the tool's definition 'Repair a 3D model' — modifies an existing 3D model to fix printability issues

POLICY

How to control meshy_repair_printability

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

policy.json

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

meshy_repair_printability 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 Meshy 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 meshy_repair_printability

What does the meshy_repair_printability tool do? +

Repair a 3D model. It is categorised as a Write tool in the Meshy 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 meshy_repair_printability? +

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

What risk level is meshy_repair_printability? +

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

Can I rate-limit meshy_repair_printability? +

How do I block meshy_repair_printability completely? +

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

meshy_repair_printability is provided by the Meshy MCP Server MCP server (meshy-dev/meshy-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Meshy MCP Server tool call.

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