STRNTH Pro

Beta

Connect your AI assistant to STRNTH

Link Claude, ChatGPT or Gemini to STRNTH and let it plan strength workouts, programmes and HIIT sessions, reuse and clone the ones you already have, then drop them straight into your app. You sign in with your STRNTH account, and nothing saves until you confirm it.

This feature is in beta, so expect it to keep changing as we improve it.

Server address

https://mcp.strnthapp.com

Paste this into your assistant's connector settings, then sign in.

What it does

Builds your training

Ask your assistant to plan a leg day, a 12 week programme or a HIIT session. It uses the real STRNTH exercise library.

Reuses what you have

It can read your saved workouts and programmes, then clone and adjust one. It can also clone a built-in programme like Push Pull Legs into your own.

You confirm first

It shows you the full workout and asks before saving. Nothing lands in your app until you say yes.

Lands in your app

Saved workouts appear in the Train tab under "AI generated", ready to start or tweak.

Before you start

  • 1.You need STRNTH Pro. Connecting an AI assistant is a Pro feature.
  • 2.Have the STRNTH app installed and know the email you sign in with.
  • 3.When your assistant asks you to sign in, use that same email. We send you a six digit code to approve the connection.

Connect Claude

Works in the Claude desktop app, the Claude mobile app and claude.ai.

Plan needed: a paid Claude plan (Pro, Team or Max) to add a custom connector, plus STRNTH Pro.

Desktop

  1. 1.Open Claude and go to Settings, then Connectors.
  2. 2.Choose Add custom connector and paste https://mcp.strnthapp.com as the URL.
  3. 3.Save, then sign in with your STRNTH email when Claude asks. Enter the code we email you and approve.
  4. 4.Ask Claude to build a workout. Confirm the preview, and it saves to your Train tab.

Mobile

  1. 1.Open the Claude app and go to Settings, then Connectors.
  2. 2.Add a custom connector and paste the server address above.
  3. 3.Sign in with your STRNTH email, enter the code and approve. Your connection carries across Claude on every device.

Connect ChatGPT

ChatGPT shares connectors across desktop, web and mobile, so you add it once.

Plan needed: a paid ChatGPT plan (Plus, Pro, Business or Enterprise), plus STRNTH Pro. Custom connectors are not available on the free tier.

Desktop or web

  1. 1.Go to Settings, then Connectors, and turn on Developer mode under the advanced options.
  2. 2.Choose Add custom connector and paste https://mcp.strnthapp.com.
  3. 3.Sign in with your STRNTH email, enter the code we send and approve.
  4. 4.Start a chat, ask for a workout, confirm the preview and it saves to your app.

Mobile

Add the connector once on the desktop or web settings above. It then shows up in the ChatGPT mobile app under the same account, with no extra setup on the phone.

Connect Gemini

The Gemini app does not let you add a custom server yet, so Gemini connects through the Gemini command line tool. This suits people comfortable editing a config file.

Plan needed: just STRNTH Pro. The Gemini command line tool is free, so there is no Gemini subscription to buy. The same is true for Cursor and the Claude command line.

  1. 1.Install the Gemini CLI, then open its settings file at ~/.gemini/settings.json.
  2. 2.Add STRNTH as a server, then run Gemini. It opens your browser to sign in.
  3. 3.Sign in with your STRNTH email, enter the code and approve.
{
  "mcpServers": {
    "strnth": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.strnthapp.com"]
    }
  }
}

The same config works in any tool that connects through a file, including Cursor and the Claude command line.

Common questions

Is it safe to connect?

Yes. You sign in with your STRNTH account using a one time code, the same as logging in. Your assistant can only suggest workouts, and nothing saves until you approve the preview.

Do I need STRNTH Pro?

Yes. Connecting an AI assistant is a Pro feature. The app is free to download, and you can upgrade to Pro inside it.

Which assistants work?

Claude and ChatGPT connect by pasting the server address into their connector settings. Gemini connects through its command line tool while its app catches up.

What can it do?

Build strength workouts, full multi week programmes and HIIT sessions, all grounded in the real STRNTH exercise library. It can also read your saved workouts and programmes and clone them, including built-in programmes like Push Pull Legs.

Where do the workouts go?

Into your Train tab under "AI generated". From there you can start them, edit them or save them like any other workout.
