Architecture

Built with FastMCP, functype (IO, Option, Either, Try), and Zod.

• IO effects: API calls return IO<never, Error, T> — lazy, composable, with built-in retry/timeout
• IO.gen do-notation: Complex tool handlers use generator-based do-notation for readable effect composition
• Option singleton: Client lifecycle managed via Option<RescueTimeClient>
• Sealed errors: ApiError | ConfigError | RateLimitError with _kind discriminator
