How to connect Claude, ChatGPT and other AI

You can connect Training Endurance to your own AI assistant — Claude, ChatGPT, Perplexity, Qwen or another — over the MCP protocol. The assistant can read your calendar, workouts, zones, health and nutrition, and, if you allow it, create and change your data. A coach can work with their athletes' data the same way.

Who can use it

The connection works for athletes with a PRO subscription and for coaches with a paid coach subscription — see What PRO gives you and how to cancel your subscription. Anyone can sign in, but without a subscription the server answers with the error "MCP server access requires an active PRO athlete subscription or a paid coach account." Once a subscription starts, access opens within a minute.

You also need to consent to AI working with your data — see below.

Server address

https://mcp.trainingendurance.com/

The server speaks MCP over the Streamable HTTP transport, and you sign in with OAuth.

How to connect

Claude Desktop

1. Click "+" in the chat box → Connectors → Manage Connectors.
2. At the bottom of the list, click Add custom connector.
3. Paste the server address and click Add.
4. Sign in to Training Endurance and choose the permissions — see "Which permissions to give".

Claude Code

Run in your terminal:

claude mcp add trainingendurance --transport http "https://mcp.trainingendurance.com/"

Then run /mcp in Claude Code, pick trainingendurance and sign in.

ChatGPT

A Training Endurance app for ChatGPT is coming; for now, the server connects in developer mode:

1. Settings → Apps → Advanced settings → turn on Developer mode.
2. Settings → Connectors → Create.
3. Paste the server address.
4. Sign in to Training Endurance and choose the permissions.

Perplexity

1. Settings → Connectors.
2. In the top-right corner, click + Custom connector and select Remote.
3. Fill in: Name — TrainingEndurance, MCP Server URL — the server address, Transport — Streamable HTTP, Authentication — OAuth.
4. Check the acknowledgement box and click Add.
5. Sign in to Training Endurance and choose the permissions.

Qwen

1. Open the Qwen desktop app and click MCP in the chat window.
2. MCP Settings → Add MCP.
3. Select Streamable HTTP and paste the server address.
4. Sign in to Training Endurance and choose the permissions.

Other clients

Any MCP client will do: Streamable HTTP transport, the server address, OAuth 2.1 sign-in. The client finds the sign-in settings by itself.

Which permissions to give

When you connect, the Training Endurance sign-in page opens at auth.trainingendurance.com, and after you sign in, the Access request screen. For each section, choose what the assistant may do: No access, Read only or Read and write.

The sections are Profile and settings, Metabolic profile, Workouts, Nutrition, Health and Athletes (for coaches).

• Read only is selected by default: the assistant sees the data but changes nothing. For it to create and change data — for example, workouts in your calendar — choose Read and write for that section.
• Don't set Profile and settings to No access: the connection doesn't work without it.

Then click Allow.

You choose the permissions only on this screen: the client's "Reconnect" button won't open it again. To change the permissions, remove the connection in the client and create it again.

Consent to AI working with your data

The assistant works with your data only if you allowed it: Settings → Settings tab → the AI and your data card → the Allow AI to work with my data switch. The app asks the same question when you sign in.

From 22 November 2026, MCP works only with this consent, and a coach sees over MCP only the athletes who gave it. If you clicked Don't allow, access over MCP closes at once, and the client gets the error "MCP server access requires your consent to AI working with your data. Allow AI in the app settings, then try again."

What the assistant can do

The assistant has more than 150 actions: calendar and workouts, the library, plans, zones and the metabolic profile, competitions, health and the daily log, nutrition, profile, sending workouts to the watch, analytics and weather. A coach also gets athletes and their tags.

Not available over MCP:

• billing, subscriptions, promo codes and the wallet;
• chat, discussions, notifications and invitations;
• deleting the account, unlinking from a coach, and consents;
• uploading and importing files, calculators, connecting services, and translation.

The server doesn't return answers larger than 5 MB. If the assistant gets an error on a big request, ask it to take a shorter period.

How to disconnect

Remove the connection in the client itself — in Claude Desktop, for example, it's in Manage Connectors. The client stops calling Training Endurance. Training Endurance itself has no list of connected assistants yet.

To close access for all assistants at once, withdraw your consent: on the AI and your data card, flip Allow AI to work with my data and click Don't allow in the window that opens. The in-app assistant and translations stop working too, and your coach's AI no longer sees you.

If it doesn't work

If the error repeats, write to support — in the chat on the site or at info@trainingendurance.com. Say which client you're connecting and what it says.
