Three things I check on every stdio MCP server:
1. stdout is the JSON-RPC channel. One stray print() breaks it, so logs go to stderr.
2. The client starts the process, often without your shell's PATH. Use absolute paths.
3. Tool descriptions are what the model reads. Keep them short and specific.

In my tests it works specifically for macOS‘ own /usr/bin/python3
For my installations I can upgrade to 3.14.10 for the fix

maki> Hello Mara. I'm ready to help. What would you like to work on?
you> please make a python script that prints shades of purple to the terminal
maki> Here's a Python script that prints shades of purple to the terminal using ANSI 256-color codes:
│ #!/usr/bin/env python3
│
│ def print_shades_of_purple():
│ # ANSI 256-color codes for purples (from dark to light)
│ purple_shades = [
│ 53, 54, 55, 56, 57, # Deep purples
│ 93, 94, 95, 96, 97, # Medium purples
│ 129, 130, 131, 132, 133, # Light purples
│ 165, 166, 167, 168, 169, # Lavender/pastel purples
│ 201, 202, 203, 204, 205 # Very light purples
│ ]
│
│ print("Shades of Purple:")
│ print("=" * 50)
│
│ for shade in purple_shades:
│ # Print colored block
│ print(f"\033[48;5;{shade}m \033[0m", end="")
│ # Print color code
│ print(f" Color {shade:3d} ", end="")
│ # Print colored text
│ print(f"\033[38;5;{shade}mPurple Shade {shade}\033[0m")
│
│ print("\n" + "=" * 50)
│ print("Done!")
│
│ if __name__ == "__main__":
│ print_shades_of_purple()
This script:
1. Uses ANSI 256-color escape sequences
2. Shows 25 different purple shades
3. Displays each shade as a colored block, the color code, and colored text
4. Works in most modern terminals
To run it, save as purple_shades.py and execute:
│ python3 purple_shades.py
The colors range from deep purples (color 53) to very light lavenders (color 205).

Oh yeah, and reminder to also run either "sudo systemctl enable nbfc_service.service" or "sudo systemctl enable nbfc_service" so it runs on startup, and also to add the command "python3 /usr/bin/nbfc-qt-tray" as a startup application to have a tray icon for speed control.
