What is Blockbench MCP?
Blockbench MCP is a plugin and Model Context Protocol (MCP) server that connects AI assistants (like Claude, Cline, or Ollama) to the Blockbench 3D modeling tool. It is designed for Blockbench users who want to control, query, or automate modeling tasks through AI agents.
How to use Blockbench MCP?
Install the Blockbench plugin by opening the desktop version of Blockbench, going to File > Plugins, clicking “Load Plugin from URL”, and pasting the plugin URL. Then configure the MCP server under Blockbench settings (Settings > General) by setting the MCP Server Port and MCP Server Endpoint (default: :3000/bb-mcp). Finally, connect your preferred MCP client (e.g., Claude Desktop, VS Code, Cline, Ollama) to http://localhost:3000/bb-mcp using the provided configuration examples.
