Splits the work between a stdio MCP server and a Fusion add-in that runs API calls on Fusion's main thread over a local TCP socket (port 9876).
Covers sketching, features such as threads, body operations, direct primitives and scene queries, and checks whether a design is in parametric or direct mode.
Can run the MCP server on one machine and Fusion on another on the same network by changing the bind and connect addresses.

Beta; tools and behaviour may change between releases.
The add-in must be installed and started in Fusion (Shift+S, Add-Ins) before the server can connect.
