MCPBridge — Claude Code MCP server: what it does, how to install
Connects Claude Code and Ollama directly to Roblox Studio and Blender. Built for 3D creators and game developers.
claude mcp add mcpbridge -- npx -y @iamjrmh/mcpbridgeWhat MCPBridge does
MCPBridge acts as a translation layer between Claude Code and creative desktop software. It routes agent instructions to external tools over two HTTP endpoints: port 7842 connects to a Roblox Studio Lua plugin, while port 7843 handles communication with Blender through Python.
The server depends on Node.js LTS. You must enable the internal MCP server toggle inside Roblox Studio's Assistant settings. Inside Blender, load MCPBridge.py through preferences and activate it with Start Bridge in the viewport sidebar. The Blender add-on fails immediately if the bridge server is not already active on localhost:7843.
What it helps with
- control Roblox Studio scenes directly from the Claude Code terminal
- send scene automation commands to Blender 3D viewports
- connect Ollama model workflows to game development environments
Example prompts for the agent
- Spawn a red sphere in the active Blender scene and position it at the origin
- Inspect the opened Roblox Studio place and attach a touch-activated door script
