Summary
Brings Blockbench's 3D modeling capabilities into your AI workflow by running an HTTP server directly from the Blockbench desktop app via a plugin. Once installed, it exposes your active models, elements, and project state through the Model Context Protocol, letting Claude or other MCP clients read and manipulate your 3D scenes programmatically. You'll configure a local endpoint (default localhost:3000) that works with Claude Desktop, VS Code, Cline, and other clients. Useful if you're generating procedural geometry, batch editing models, or want conversational access to Blockbench operations without clicking through menus. The setup requires loading the plugin URL in Blockbench and pointing your MCP client at the local server endpoint.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
