Solve puzzles with an AI agent

An AI agent or your own program can now open puzzles from your rotation, save how you did, and read your figures and puzzle history.

Connect an AI agent through MCP and ask it for a puzzle. It gets a random puzzle from your rotation with the game moves that led to it, keeps the solution hidden while you solve, and saves one result for each play, missed at the first wrong move or when the solution is shown and solved for a clean finish.

Puzzles stay with signed-in accounts. A hosted connection asks you to allow puzzle access when you sign in, and a personal token needs the puzzles:read scope to read puzzles and puzzles:write to save results. An agent cannot reset your puzzles; Reset puzzles stays with you on the website.

Developers get the same rotation, results, history and reset through the account API and its Python, TypeScript and Kotlin clients.
