STRNTH Pro

Connect your AI assistant to STRNTH

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

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.

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.

  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. A paid ChatGPT plan is required.

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.

  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.
