Elegoo Mcp Server
Elegoo MCP Server
A local MCP (Model Context Protocol) server for controlling Elegoo 3D printers via the SDCP protocol.
100% local - no cloud dependencies.
⚠️ Your computer and printer must be on the same local network (WiFi or Ethernet).
Tested with Elegoo Centauri Carbon and Claude Desktop. Should work with any MCP-compatible client (VS Code, Cursor, etc.).
