# Use Meso in Claude or ChatGPT

Connect your Meso account to Claude or ChatGPT and talk to your training: ask what today's session is, compare what you lifted with what was prescribed, or log a session by typing or dictating it. The assistant works from your real Meso data; your program still lives in Meso.

## Connector address

```
https://meso.fitness/member/mcp
```

You also find it, with a copy button, in the Meso app under **Profile → Use Meso in Claude or ChatGPT**.

## Before you start

You need a Meso account. Start free at https://meso.fitness/signup.html.

## Connect Claude

1. Open **Settings → Connectors → Add custom connector**.
2. Paste `https://meso.fitness/member/mcp` and add it.
3. Claude opens Meso's sign-in. Sign in with your Meso account and approve the connection.

## Connect ChatGPT

1. Turn on developer mode, then open **Settings → Apps & Connectors → Create**.
2. Paste `https://meso.fitness/member/mcp` as the connector URL.
3. Sign in to Meso when ChatGPT asks, and approve the connection.

## What the connection can do

| Tool | What it does |
|---|---|
| `get_program` | Reads your current cycle and phase, and each training day's exercises with prescribed sets, reps, RPE target and rest. Read-only. |
| `list_sets` | Reads your recently logged sets, session by session. |
| `log_set`, `batch_log_sets` | Logs completed sets to your program — one set, or a whole session from a text or voice summary. |

When you log a whole session, the assistant can ask Meso's four readiness questions (sleep, soreness, fatigue, stress). A poor or severe day then stays out of your progression, the same as an adjusted session in the app. It only sends answers you gave.

**Not yet:** swapping exercises, changing equipment, or rebuilding your program from a chat. Make those changes in the Meso app.

## Access and privacy

- The assistant acts as you: every call runs under your own sign-in, so it can read and log only your data. Meso holds no key that reaches anyone else's.
- Access is all or nothing: a connected assistant can use every tool above.
- What you say in the chat is handled by Claude or ChatGPT under their terms; Meso receives only the tool calls.
- Meso's privacy notice covers connected assistants: https://app.meso.fitness/privacy

## Revoke access

In the Meso app, go to **Profile → Use Meso in Claude or ChatGPT → Connected assistants** and choose **Revoke**. That ends the assistant's sign-in; to use Meso there again you'd connect it again. You can also remove the connector in Claude or ChatGPT.

## For agents

The member endpoint uses OAuth 2.1; its protected-resource metadata is at https://meso.fitness/.well-known/oauth-protected-resource/member/mcp. The public product server `https://meso.fitness/mcp` needs no sign-in and answers questions about Meso's methodology, pricing and availability. Details for developers: https://meso.fitness/developers.md

## Scope

Meso is for resistance-training programming. It doesn't give nutrition, cardio-endurance, injury or medical advice; for sharp or worsening pain, see a professional.
