Muscla for AI assistants

Last updated 13 November 2026

Connect Muscla to Claude, ChatGPT or another assistant and ask about your own numbers.

You find the address in the app under You → Settings → AI assistants, where you can copy it. The same address works in every assistant. You set up the connection from inside the app once Muscla launches.

Ask, for example:

  • “How has my bench press developed since summer?”
  • “Did I get enough protein this week?”
  • “Log my dinner: salmon with potatoes.”

You need Muscla Pro with an account (sync on) and an assistant that supports connectors (MCP).

What it can do

It reads every workout and set, estimated 1RMs, records, weekly sets per muscle group, your training plan, your body weight trend and your food diary against your targets.

It writes, if you allow it: a meal, water, a weigh-in, a workout you forgot, a new routine or your meals for the next days.

Connect Claude

  1. In Claude, open Settings → Connectors → Add custom connector.
  2. Name it Muscla, paste the address and choose Add.
  3. Next to Muscla, choose Connect. Muscla’s sign-in page opens.
  4. Sign in and choose what Claude may see and change.

Connect ChatGPT

Muscla is coming to the ChatGPT app directory, and you will find it there once it is approved. Where ChatGPT lets you add your own connector, the address works there too.

Other assistants

Gemini CLI, VS Code, Perplexity and others: add the address as an MCP server and sign in with your Muscla account when asked.

You decide what it can see

  • Per kind of data. For training, body weight and food, you choose separately whether the assistant may read, and whether it may add, change and delete.
  • Only what it asks for. The assistant receives the data you allowed, and only when it asks for it in a conversation.
  • No Apple Health data. Data from Apple Health, such as heart rate or sleep, is never shared with an assistant.
  • Confirmation before changes. The assistant is instructed to confirm with you before it writes anything. Everything it adds or changes shows in the app as made through that assistant.
  • Disconnect at any time. In the app, under You → Settings → AI assistants, you see every connection, change what it may do or disconnect it. This takes effect at once.

What you share goes to the assistant’s provider, for example Anthropic or OpenAI, which handles it under its own privacy policy. Muscla does not decide what the provider keeps. Details are in our Privacy Policy.
