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.

Server URL: https://mcp.tallyworkout.app/api/mcp Transport: Streamable HTTP · Auth: OAuth 2.1 (PKCE, dynamic client registration) 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)

1. Copy the server URL: https://mcp.tallyworkout.app/api/mcp
2. In a browser, open claude.ai → Settings → Connectors → Add custom connector. Name it Tally, paste the URL.
3. 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.
• Privacy policy: mcp.tallyworkout.app/privacy

About this repo

The server implementation lives in Tally's backend (closed source); this repo is the connector's public home — docs, config snippets, and the issue tracker for bug reports and tool requests.
