- Homepage: https://github.com/sandraschi/blender-mcp

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "manage_object_construction",
    "arguments": {}
  }
}
```

## Why manage_object_construction is rated Medium

The name suggests creating or modifying 3D objects in Blender (construction implies building/modifying). In the context of a Blender MCP server, this likely creates or updates scene objects, which maps to Write. However, with no description, confidence is low and severity is medium since misuse could corrupt or alter a 3D scene but is generally reversible.

From the tool's own definition: "Tool name 'manage_object_construction' — description is empty and uninformative."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Blender:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "manage_object_construction": {
      "limits": [
        {
          "counter": "manage_object_construction_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
