MCP TIMER FOR CLAUDE

The timer that
lives inside Claude.

Say start. It times, labels, and logs your session. No extra app, no forgotten timers.

SPLITS

No splits yet. Press Split while the clock runs.

IN-CHAT CARD

Ask for five minutes.
Watch them tick.

When you start a timer, Claude drops this card into the conversation. It counts down live, flashes TIME'S UP at zero, and the finished run lands in your history.

It runs where you already work.

Starting, stopping, and labeling all happen inside Claude, with a live timer card right in the chat. Your history stays on your machine and syncs to the cloud only when you ask.

Never forget a timer again

Starting and stopping happens in the chat you are already in, and the wall display keeps it visible.

GUARDRAIL

Auto-stop guard

A runaway timer gets flagged so you can stop and trim it. Never bill a timer you forgot overnight.

SOUND

Rings at zero

The wall display chimes when a countdown hits its target, the in-chat card flashes TIME'S UP, and Claude announces the official time.

POMODORO

Pomodoro countdowns

Say start a 25 minute pomodoro. The card counts down in the chat and the timer auto-stops at zero.

OPTIONAL

Fun mode

XP, ten ranks, twelve achievements, and confetti on personal bests. All optional, and off by default.

OPEN SOURCE

Free local MCP server, forever.

TimerMCP is an open source Model Context Protocol server that turns Claude into a talking stopwatch, precise to the millisecond. Install it once and time anything by voice, no account required.

Your history lives in ~/.timermcp on your own machine. Nothing leaves your computer until you choose to sync.
