Connect Simma to Claude

Claude is the assistant where everything works, for everyone. Once Simma is connected, a coach gets their whole squad and an athlete gets their own training — reads and writes, with the safety gates intact. If you have a choice of assistant, start here.

You do not need a Simma account first. Connecting creates one.

Step by step

  1. Open Simma in Claude's directory: claude.ai/directory/simma. It is listed under community connectors.
  2. Press Connect. Claude opens Simma's sign-in page in your browser.
  3. Sign in, or sign up. If you already use Simma, sign in with that email and password. If not, choose sign up on the same page: an email, a password, and the code Simma emails you to confirm it.
  4. Say who you are. New accounts get one short screen: I coach athletes, or I train. A coach enters their name and, optionally, the business name athletes will see. An athlete enters their name and their levels in the sports they do, then can link Garmin on the spot — turn on Historical data on Garmin's page so the last sixteen weeks load straight away.
  5. Back to your assistant. The last button returns you to Claude, signed in. Start a new conversation and Simma's tools are there.

That is the whole setup. There is nothing to install and no address to paste.

Your first questions

If you're a coach:

"Who in my squad needs attention this week?"

"Give me the full picture on Sarah before I write to her."

"Show me every swim this month where the main set faded."

If you're an athlete:

"How is my training going?"

"Walk me through my last long ride."

"Am I pacing my swims more evenly than I was?"

Claude picks the tools; you never call them by name. For what an athlete can ask, see Ask Your Assistant About Your Training; for a coach, Every Simma Connector Tool, and What to Ask For.

A coach's athletes

Coaches see the athletes on their squad. An athlete joins a squad with the coach's invite code, which Claude can hand out on the coach's behalf ("what's my invite code?") and an athlete can use from their own Claude ("join my coach with code …"). Until an athlete has a coach of their own, Simma's house coach account holds them, so their training is never orphaned.

Permission prompts

The first time Claude uses each tool it may ask you to allow it. Choose always allow for the tools you're happy with and it stops asking. The tools that only read your data are marked as read-only, so Claude can tell them apart from the ones that change something.

The one action that is never silent is sending a message. Before a coach's draft goes to an athlete, or an athlete's message goes to their coach, Simma shows you the full text and asks you directly. The assistant can't answer that prompt for you.

Signing out, or switching accounts

Every time you connect, Simma asks you to sign in afresh, so switching between accounts is just disconnecting and connecting again. If you want to be certain the browser session is cleared — on a shared computer, say — ask Claude to sign you out of Simma and it will give you the link that does it.

Adding Simma by URL instead

If you would rather add Simma as a custom connector — a workspace that manages its own connectors, say — the address is:

https://mcp.getsimma.com/mcp

Paste it as a new custom connector, leave the OAuth client settings alone (Simma registers the client itself), then connect. The sign-in and sign-up are the same as above. Simma is also on the official MCP Registry as com.getsimma/simma.

Also using Claude Code?

The same server works from the terminal. Simma registers a fixed callback port for it, so pass that port when you add it:

claude mcp add --transport http simma https://mcp.getsimma.com/mcp --callback-port 8765

Then run /mcp inside Claude Code and choose Simma to sign in.

Who can see what

The conversation you have with Claude stays between you and Claude. Simma never receives it — Simma sees the requests for data, not the words around them. The only thing that ever reaches another person is a message you deliberately send.

Two things worth knowing plainly. Anthropic, as the provider of Claude, processes your conversation under its own terms. And an athlete who has no coach of their own is attached to Simma's house coach account, which can read their training data in the same way any coach can; see the privacy policy for what that means.
