Connect your own AI to your training log

What is actually different

• An open protocol, not one assistant. MCP is a standard, so this is not a single ChatGPT integration. Other lifting apps expose a REST API and community servers wrap it; here the server is the product surface.
• First-party. The server is built and run by us against the same data the app uses, so it does not drift behind the product the way a third-party wrapper does.
• Writes are proposals. A token with write scope can propose a program change. Applying it needs you, in the app. An agent cannot rewrite your training while you are asleep.

What your client can read

• Recent workouts, and any single session in full
• The current program and what the next session is
• Personal records and estimated rep maxes
• Per-muscle recovery and weekly volume
• Strength level against sex-aware standards
• The rule behind any prescribed weight, and the paper behind the rule
• Plate breakdown and the warm-up ramp for a given weight

What it can propose

• Propose a program change
• Propose a goal, habit or profile change
• Propose an update to body stats

Body measurements and progress photos are owner-only. They are never exposed to an MCP client, and never to Coach.

Connecting

Two ways in. OAuth 2.1 with dynamic client registration, for clients that support it — the authorization server metadata is published at the standard well-known path. Or a personal access token from Settings, for a local client like Claude Desktop or Cursor. Tokens are scoped: read-only unless you explicitly grant write.

The connector is part of Reppit Premium. Everything it reads is your own data.
