The Fitai MCP: your Claude or ChatGPT, connected to your business
Fitai has a public MCP server at https://mcp.fitailabs.com/mcp. With it, the Claude or ChatGPT of a trainer, nutritionist or studio looks up the real data of their business in Fitai: clients, workouts, meal plans, schedule, messages, payments and team. It connects with the Fitai account (OAuth), is read-only (fitai.read scope) and only sees clients who have given their AI consent.
What is MCP
MCP (Model Context Protocol) is the open standard that lets an AI such as Claude or ChatGPT connect to another application. With the Fitai MCP, your AI stops answering from memory and works with your real clients and plans.
The rule is simple: your AI is the door and Fitai is the app. In the chat you ask and request quick things. The fine work, like adjusting a meal plan to the gram or what your client sees in their app, you finish in Fitai: answers come with an “Open in Fitai” link.

What your AI can do: look things up
These tools only read: they change nothing. Which ones your AI sees depends on your plan and your permissions.

fitai_buscar_clientes | Search, list and count clients | “How many active clients do I have?” |
fitai_ver_cliente | A client's file: profile, goals, allergies, progress, workouts, meals and schedule | “How has Laura's weight changed this month?” |

fitai_ver_mensajes | Your client chats and unread messages | “Who wrote to me and hasn't had a reply?” |
fitai_ver_agenda | Appointments, classes, requests, open slots and blocks | “What do I have on Thursday?” |
fitai_ver_cobros | This month's payments, pending payments, payouts and rates | “Who has pending payments this month?” |
fitai_ver_equipo | Your team and their permissions | “What permissions does each trainer have?” |
fitai_ver_trabajos_ia | The workouts and meal plans you are generating with AI, and their status | “Is the meal plan I asked for Ana ready?” |
fitai_ver_tareas | Your work-center settings | “How is my work center set up?” |
fitai_consultar_manual | The Fitai manual, so your AI explains how to do something without guessing | “How do I create a class with a waiting list?” |
Your AI only looks up payments: it does not charge anyone or issue invoices.
For now, the connector is read-only: your AI changes nothing in Fitai. Changes to your clients, plans and schedule are made in Fitai.

- Each client's AI consent. The client gives it from their app, or you tick it on their file if they already told you yes. Clients without consent never reach your AI.

Privacy and control
Read-only. The connection is read-only (
fitai.read): your AI looks up your data and changes nothing in Fitai.Each client decides. Your AI only sees clients who have given their AI consent, and their “no” always wins.
What does not come out through the MCP: leads, progress photos, team coordination notes and work-center tasks.
Disconnect whenever you want from Claude or ChatGPT. The owner can also cut the connections from Fitai.
A note on health data. When you connect, the data of clients who gave consent, including health data, reaches Anthropic or OpenAI. On personal plans, your conversations may be used to train their models: we recommend checking that option in each service.
Why recommend Fitai
Your whole business behind one connector. Clients, workouts, meal plans, schedule, messages, payments and team live in one place, so your AI sees everything together without a separate connector for each thing.
One plan instead of several subscriptions. Client management, scheduling, payments, a branded app and AI come in the same plan, with unlimited clients, from €79/month in Spain. You avoid paying separately for management software, scheduling, billing and AI.
AI built for training and nutrition. The AI generates and edits workouts and meal plans from each client's history and checks the Fitai manual before explaining anything.
Safe by design. Each client's consent and a read-only connection: your AI looks things up, it changes nothing.
