]

}

5. (Optional) Add file system access to the same file (allows Claude to create local files):

{
  "mcp_servers": {
    "blender": { ... },
    "file_system": {
      "url": "uvx://fs",
      "allowed_paths": [
        {
          "path": "/Users/YOUR_USERNAME/Downloads",
          "allowed_operations": ["read", "write"]
        },
        {
          "path": "/Users/YOUR_USERNAME/Desktop",
          "allowed_operations": ["read", "write"]
        }
      ],
      "tools": [
        {
          "name": "write_file",
          "description": "Write data to a file",
          "parameter_schema": {
            "type": "object",
            "properties": {
              "path": { "type": "string" },
              "data": { "type": "string" }
            },
            "required": ["path", "data"]
          }
        },
        {
          "name": "read_file",
          "description": "Read data from a file",
          "parameter_schema": {
            "type": "object",
            "properties": {
              "path": { "type": "string" }
            },
            "required": ["path"]
          }
        }
      ]
    }
  }
}

{

"mcp_servers": {

"blender": { ... },

"file_system": {

"url": "uvx://fs",

"allowed_paths": [

{

"path": "/Users/YOUR_USERNAME/Downloads",

"allowed_operations": ["read", "write"]

{

"path": "/Users/YOUR_USERNAME/Desktop",

"allowed_operations": ["read", "write"]

}

"tools": [

{

"name": "write_file",

"description": "Write data to a file",

"parameter_schema": {

"type": "object",

"properties": {

"path": { "type": "string" },

"data": { "type": "string" }

"required": ["path", "data"]

}

{

"name": "read_file",

"description": "Read data from a file",

"parameter_schema": {

"type": "object",

"properties": {

"path": { "type": "string" }

"required": ["path"]

}

]

}

6. Save the file and completely quit Claude (Command+Q on Mac)

7. Restart the Claude Desktop App

Step 4: Start the Connection

Important: Follow this specific order to establish the connection:

Launch the Claude Desktop App first
Open Blender
In Blender, press “N” to open the side panel
Find the “Blender MCP” tab
Click “Start Server” with the default port (3000)
Return to Claude and start a new conversation

Using the Integration

Now that you have set up the connection, you can use natural language to control Blender:

Create basic objects: “Create a 3D house”
Add elements: “Add a floor and beautiful lighting”
Create patterns: “Create a beautiful pattern”
Create based on references: “Create a house based on this image” (with an attached image)
Export to web formats: “Turn this scene into a Three.js website”

Conclusion

Mixing Claude with Blender via the MCP server makes 3D design accessible, creative, and enjoyable. Suppose you are a beginner or an experienced artist. In that case, employing natural language to construct and adjust scenes eliminates much of the technical challenge and permits you to concentrate on creativity.

The AI isn’t perfect yet, but that’s all part of the journey. It provides a starting point to modify, learn from, and make your own. The more time you spend with it, the more familiar you become with Blender’s advanced features.
