Your CNC machine,
connected to your AI assistant

The first MCP server that connects your AI assistant to a professional CNC machine simulator.

Runs locally on your Windows PC alongside Eureka 3X. Connect it once to Claude Desktop, Cursor, or any desktop MCP client - then simulate and verify G-code programs without leaving your chat window.

AIRunning simulation on Haas VF-2 digital twin...
AIEureka finished the simulation. Here the results... There is a collision at N0042. The tool holder hits the left fixture clamp during a rapid move. The Z-level drops to Z-82.4 while still in G00. I can modify the clearance plane to Z-60 to avoid this. Should I proceed?

How it works

Two workflows,
one conversation

Install the Eureka MCP server locally on your Windows PC — the same machine where Eureka 3X runs. Connect it once to your desktop AI client. Then choose how you want to work: verify programs coming from CAM, or write and refine G-code directly with the AI.

Flow A
Simulate & analyze G-code from CAM

Post your G-code from Fusion 360, Mastercam, or any CAM system. Your AI client sends it to the local Eureka MCP server, which runs the simulation on your machine's digital twin and reports back any collisions, axis violations, or program errors — directly inside the chat.

Flow B
Create & refine G-code via AI

Describe what you need in plain language. The AI writes the G-code and sends it to the local Eureka MCP server for verification on your machine's digital twin. The AI fixes any issues and re-simulates — looping until the program is clean. Export the verified file directly to your CNC machine.

Flow B — Create & refine G-code via AIAnimated loop: you prompt the AI, AI writes G-code, Eureka 3X verifies, issues return to AI which fixes and re-simulates, clean program exits to machine.Flow B — Create & refineYou"Write a facingprogram for Haas"AI writesG-code generatedfrom your promptEureka 3XSimulates ondigital twinAI fixesRewrites affectedlines, re-simulatesClean ✓Export verified.nc to machineissuesfoundcleanAI writes and refines G-code — Eureka 3X verifies each iteration automatically
