Connect
Three steps, then ask from wherever you talk to Claude.
No API keys and nothing to install. Your account holds what the GM remembers — your Sleeper usernames, your leagues, your own player tags — so a new session never has to ask twice.
An email address and a password. That account is what the connector signs into, and what your remembered leagues hang off.
Create an accountAlready have one? The same form signs you in.
Give your Sleeper username and it finds your leagues and identifies your roster in each. Public on Sleeper, so no login there is needed. More than one account is fine — adding another adds to the first.

- Paste the URL and save.
- Click Connect. A tab opens: sign in, then allow it.
- Back in the chat, ask about your league.
Create your account first — the connector signs you in through it, and that account is what remembers your leagues.
Then say this, in your client
“Remember me, my Sleeper username is jonthestone.”
“It’s my pick — who should I take?”
“Someone offered me Bijan for Gibbs and a kicker — what does that move?”
“Who should I start this week?”
When several leagues are remembered, the tools list them and ask which — they never pick one for you.
