Hello Brainfuck
A greeting tool written entirely in Brainfuck - the famously minimalist esoteric programming language created by Urban Müller in 1993.
About Brainfuck
Brainfuck has only 8 commands:
>- Move pointer right<- Move pointer left+- Increment cell-- Decrement cell.- Output cell as ASCII,- Input to cell[- Jump past]if cell is zero]- Jump back to[if cell is non-zero
Everything else (including comments) is ignored.
How It Works
The program builds each ASCII character using multiplication loops. For example, to print H (ASCII 72):
>+++++++[-<++++++++++>]<++.[-]This creates 7 in a cell, multiplies by 10 (using a loop), adds 2, then prints.
Usage
CLI
enact run enact/hello-brainfuckMCP (for LLMs/Agents)
Call enact__hello-brainfuck with no arguments.
Output
Returns JSON:
{"message":"Hello from Brainfuck!"}Why?
Because we can. And because every tool registry deserves at least one Brainfuck program.
