Connecting FitHarness to Claude

• A paid Claude plan. Custom connectors aren't available on the free tier.
• A FitHarness account (you're signed in, so you have one).

1. 1. In Claude, click Customize at the bottom of the left sidebar. A settings window opens.
2. 2.In that window's left menu, under Customize, click Connectors.
3. 3. Click Add (top right) → Add custom connector.
4. 4. Give it a Name— “FitHarness” works — and paste this into Remote MCP server URL:
   https://fitharness.com/api/mcpCopy
5. 5. Leave everything under Advanced settings blank, and leave Individual sign-in switched on. That setting is what ties the connector to your account — see below. Then click Add.
6. 6. Claude opens a sign-in window. Use the same Google accountyou signed into FitHarness with, then approve access. The approval screen shows which email it's connecting as — check it matches.
7. 7. Start a new chat and say “I'm new to FitHarness — set up my account.”

Individual sign-in — leave it on

Each person signs in and gets their own connection, which is exactly how FitHarness works: your token is bound to your account and reaches only your data.

OAuth Client ID / Secret — leave blank

FitHarness registers Claude as a client automatically, so there's nothing to paste. Those fields are for servers that need credentials issued by hand.

Claude signed in but the app is still locked

Connecting isn't enough on its own — the setup conversation is what unlocks it. Ask Claude to set up your account and answer its questions.

“Token is not bound to a user”

An old connection from before your account existed. Remove the connector in Claude and add it again.

Claude can't see data you know is there

You may have approved the connector with a different Google account than the one you use here — each account has its own separate data. Remove the connector and redo the sign-in, checking the email on the approval screen.

Claude doesn't know about a new feature

Claude reads the instructions once, when it connects. Reconnect the connector to pick up new tools.

Still stuck

Ask whoever invited you to unlock your account manually — an admin can do that without a working connector, so you won't be stranded.

The connector reaches only your own training, nutrition, body and wellness data. Access is tied to the account you approved with, so it cannot read anyone else's. Revoke it any time from Claude's connector settings — your data stays here.
