Two ways to access your athletes

Choose the path that fits how you already work with Intervals.icu.

Option A

IcuSync invite

Your athletes sign up to IcuSync and send you a coach invite by email. Works regardless of whether you have Intervals.icu coach access.

  • No IcuSync account needed for you
  • Athlete controls which tools to grant
  • One MCP URL covers your full roster
Option B

Direct Intervals.icu

Already coaching athletes on Intervals.icu? Connect your own account via OAuth and Claude sees your full coached roster automatically.

  • Athletes need zero IcuSync setup
  • All 14 tools available for all athletes
  • Requires your own IcuSync subscription
Option A

How the IcuSync invite works

1

Athlete sends invite

Your athlete logs in to IcuSync, enters your email and selects which tools to grant.

2

You get an MCP URL

An email arrives with your personal MCP URL. Add it to Claude as a custom connector.

3

Start coaching

Ask Claude to list your athletes, select one, and start working with their training data.

Option B

How direct Intervals.icu access works

This uses your existing coach relationship on Intervals.icu. Your athletes only need to have accepted your coaching request there. No IcuSync account, no invite email, nothing on their end.

1

Subscribe to IcuSync

Sign up for your own IcuSync subscription, then connect your Intervals.icu account via OAuth on your dashboard.

2

Add IcuSync to Claude

Copy your MCP URL from your IcuSync dashboard and add it as a custom connector in Claude. Your coached athlete roster is detected automatically.

3

Start coaching

Ask Claude to list your athletes and select one. All 14 tools are available for every athlete you coach on Intervals.icu.

Key details

  • Option A: no IcuSync account needed for you. Your athletes hold the subscription. You connect via a token they grant you.
  • Option A: one URL covers all your athletes. If multiple athletes invite the same email, your single MCP URL gives access to all of them.
  • Option B: zero athlete setup. If your athletes have accepted your coaching request on Intervals.icu, they need to do absolutely nothing. You connect your own account and their data is immediately accessible.
  • Option B: all 14 tools included. Unlike the invite system where athletes choose which tools to grant, direct coach access gives you all read and write tools for every coached athlete.
  • Works on any Claude plan. The free plan includes one custom connector slot. Paid plans (Pro, Max, Team) give you additional connector slots.
  • Also train yourself? If you have your own IcuSync account and train as well as coach, log in to your IcuSync dashboard and send a coach invite to your own coach email address. Then ask each of your athletes to do the same. Once set up, replace your Claude connector URL with your coach token URL instead of your athlete token. Your coach token covers both your own training data and all your coached athletes in one place. Just use select_athlete in Claude to move between yourself and your athletes.

How to add the connector in Claude

Step by step
  1. 1Open Claude on the web (claude.ai) or desktop app and go to Customize. Once added there, the connector syncs automatically to the Claude mobile app.
  2. 2Click the + button next to Connectors to add a Custom connector
  3. 3Paste the MCP URL from your invite email and save
  4. 4Start a new chat, then ask Claude to list your athletes
  5. 5Tell Claude which athlete you want to work with using select_athlete

Heads up before connecting

Claude may briefly show a warning that it couldn't reach the IcuSync server when you add or re-add the connector. This is expected and clears on its own. If IcuSync appears in your Connectors list, your connection is working.

Available tools

With Option B (direct Intervals.icu), all 14 tools are always available for every athlete. With Option A (IcuSync invite), the tools available depend on what each athlete grants when sending the invite.

Manage your token

Lost your MCP URL or need a fresh token for security? Enter your coach email below. We send a confirmation link first to verify it is you before taking any action.

This applies to Option A (IcuSync invite) only. If you use Option B (direct Intervals.icu), your connection is managed from your IcuSync dashboard.

Resend my MCP URL

Sends your existing MCP URL back to your email. Your token does not change.

Regenerate my token

Issues a new token and invalidates the old one. Update your Claude connector URL after regenerating.
