Hey ado1,
I would highly recommend working with agentic AI on a paid subscription tier, such as a "Claude Pro" account. API requests will cost you a fortune; this is definitely not the way to go about it in my opinion.
As for the MCP tokens, I honestly have no idea — I didn't pay attention to how many it used.
The MCP server is the first part of my plan to automate modelling. My initial idea was to go from a hand-drawn sketch to a NURBS prototype in the shortest possible time. I am currently working on the second part, which will involve taking a hand-drawn or AI-generated image and modelling it in MoI. It's a long shot, but the initial tests are promising.
