Tally Workout MCP server

Docs for the remote Model Context Protocol server of Tally Workout, a free iPhone strength log. Your AI agent reads your training history and plans workouts in the Tally app. You log every set at the gym. Next week, the agent plans from what you actually lifted. When you ask, the agent can also log, change or delete a finished workout, and you can undo each change for 7 days.

It works with Claude, Claude Code, Codex, ChatGPT, Muse, Hark, Perplexity, Dots and any MCP client that supports OAuth 2.1 or a bearer token.

This repo holds the public docs. The server is first-party and closed source. It runs as part of the Tally backend.

Endpoint

https://mcp.tallyworkout.app/api/mcp

Transport: Streamable HTTP. No SSE-only mode.
Auth, option 1: OAuth 2.1, authorization code + PKCE (S256), public client, dynamic client registration (RFC 7591). Scope: workouts.
Auth, option 2: an API key, for clients without OAuth. Create it in the Tally app under Settings → API keys. Send it as Authorization: Bearer tally_ct_…. A key is Read only, Read and plan, or Full access. Only a Full access key or an OAuth connection can change finished workouts. Keys do not expire. Revoke a key in the app.
Discovery: /.well-known/mcp-server, agent brief (llms.txt).

Rules

Finished workouts change only when the user asks. log_workout, update_workout, delete_workout and restore_workout need a Full access key or an OAuth connection. update_workout and delete_workout need the workout's version from get_workout as expectedVersion. Each change keeps the earlier content for 7 days: get_workout_versions lists it and restore_workout brings it back. All except restore_workout need a phone on the current Tally app.
Some days are protected. A day the user built in the app, or edited, is protected. The plan, update, move and delete tools skip it unless the user asks for an override.
Edits check the version. If a day or a finished workout changed after the agent read it, nothing is written and the result reports a conflict.
Each user sees only their own data. OAuth tokens and API keys are scoped to one account. The user can revoke them at any time.
