Overview

The Blockbench MCP plugin transforms Blockbench, a 3D model editor, into an MCP server, enabling AI assistants to interact with and manipulate 3D models directly. It provides both a plugin for Blockbench and client configuration instructions for various MCP-compatible environments including VS Code, Claude Desktop, Ollama, and others. The plugin supports real-time integration between AI systems and 3D modeling workflows, allowing for automated model manipulation and generation through the MCP protocol.

Try asking AI

After installing, here are 6 things you can ask your AI assistant:

you:AI-assisted 3D model editing and manipulation in Blockbench

you:Automated texture generation for 3D models

you:Integration of AI model generation tools with 3D workflows

you:What is the default port for the Blockbench MCP server?

you:Which AI clients are compatible with this MCP server?

you:Can I add custom tools to the MCP server?

When to choose this

Choose this when you're working with Blockbench for 3D modeling and want AI assistance in your workflow without leaving the application.

When NOT to choose this

Don't choose this if you're not using Blockbench for 3D modeling, as this MCP server only integrates with that specific platform.
