This creates an mcp.json file with minimal configuration of the command your mcp server will run, in our case the repo already has that so step #4 to #7 is not needed <br><img width="572" height="112" alt="image" src="https://github.com/user-attachments/assets/f80488df-9a40-4cfb-a25d-c2ea8791d53d" /> <br><img width="572" height="227" alt="image" src="https://github.com/user-attachments/assets/0f2e8946-5101-48dc-9f7e-160b89597383" />
