Tally Workout Tracker
Tally MCP — the workout app Claude can write to
Tally is a fast, offline-first workout tracker for iOS. This is its first-party remote MCP server: Claude reads your real training history and writes planned workouts back into the app. Talk through your program in conversation — exercises, sets, progressions — say "put it in Tally," open the app, and your week is planned, synced, and ready to log.
Most fitness MCPs are read-only. Tally's is a full round-trip: plan conversationally, log at the gym, and Claude respects your gym-floor edits — anything you change in the app is treated as truth and never overwritten.

Cost: free — bring your own Claude subscription
Requirements
- The free Tally iOS app + a Tally account
- claude.ai custom connectors require a Claude Pro or Max plan
- Full setup guide with screenshots: tallyworkout.app/connect
Connect
claude.ai (one-time, in a browser)
- Copy the server URL:
https://mcp.tallyworkout.app/api/mcp - In a browser, open claude.ai → Settings → Connectors → Add custom connector. Name it Tally, paste the URL.
- Sign in with your Tally account when asked. Then try: "Plan my next week of training and add it to Tally."
Connectors can't be added from Claude's phone app itself; once added in a browser they sync to Claude's mobile and desktop apps automatically.

Tools
| Tool | Access | What it does |
|---|---|---|
get_training_context | read | Training snapshot: recent sessions, streaks, patterns — grounds programming advice in what you actually did |
get_workout_history | read | Completed workout history (sets, reps, weights) over a date range |
get_planned_workout | read | Read a planned day (for read-modify-write edits) |
search_exercises | read | Search Tally's exercise library (800+ movements) |
plan_workout_day | write | Create or replace one planned day |
plan_workout_range | write | Plan a multi-day range — whole weeks or blocks in one call |
All tools carry MCP annotations (readOnlyHint / destructiveHint). Writes
never touch days you've edited in the app (user_modified protection), and
every write is stamped with a batch id for auditability.
Privacy & security
- OAuth 2.1 with PKCE; access is scoped to your Tally account and revocable anytime from Claude's connector settings.
- Server-side analytics record tool names and timing only — never workout content.
