What it does
Blockbench MCP Plugin adds an MCP server to Blockbench, a model editor for games. The server works inside the editor at `http://localhost:3000/bb-mcp` or standalone: `npx -y github:jasonjgardner/blockbench-mcp-plugin --root ./models`. Connection: `claude mcp add blockbench --transport http http://localhost:3000/bb-mcp` or `codex mcp add bbmodel -- npx -y github:jasonjgardner/blockbench-mcp-plugin --root /path/to/models`. Version 1.10.0 from 01.10.2026, GPL-3.0 license.
Who it is for. For game and mod creators who build models in Blockbench and want an agent to help with geometry and textures.
Good fit when
- You need to build models in Blockbench with an agent
- You need an MCP server inside a model editor
- You need to work with a models folder without launching the editor
Not a fit when
- You need a non-copyleft license: this is GPL-3.0
- You cannot let an agent change model files
Example request
Build a simple 16 by 16 by 16 crate cube in Blockbench with a wood texture and export the modelLimitations
The agent changes models in the editor and files in the given folder, so access is extended: work with copies. The GPL-3.0 license imposes conditions on distributing derivative works. The server listens on a local address, do not open it outward.
How to disable. Disable the plugin in Blockbench and remove the server entry from the client.
