Setting Up MCP for Blender

1. Open Claude AI App.
2. Click on the hamburger menu at the top left.
3. Navigate to File > Settings > Developer > Edit Config.

This will open the Claude folder in Finder/File Explorer, where the claude_desktop_config.json file is automatically created by the app.

1. Open claude_desktop_config.json with any text editor.
2. Scroll down to the Community Servers section on the Blender MCP page and locate the following JSON code snippet:

{ "mcpServers": { "blender": { "command": "uvx", "args": [ "blender-mcp" ] } } }

1. Copy and paste this JSON snippet into claude_desktop_config.json.
2. Save and close the file.

Verify the Connection with Blender on Claude AI

Ensure that the setup is correct by checking if the connection is recognized in Claude AI.
