book and quill, sign activation on the server

You can use a book and quill with a Lectern and a redstone comparator to emit varying redstone signal strengths based on the currently open page

Signal Output: Placing a Lectern with a book behind a redstone comparator allows the comparator to read the open page and output a signal strength from 1 to 15.

Calculation: The signal strength depends on the current page number and the total number of pages in the book. A 15-page book increases the signal strength by 1 for each page turned.

Pulse: Turning a page emits a brief 2-game-tick pulse of maximum signal strength (15) into the block beneath the lectern
