Does Claude have a built-in fantasy football skill?

No — Claude doesn't ship with fantasy-specific knowledge any more than it ships with your league's data. What it has is a general connector system, and TradeGauge is one server you can add to it from Settings → Connectors.

Is my Sleeper info safe to share with Claude?

get_league_roster only reads public roster data using a username or league ID — the same information you'd type into league chat. There's no password or account login involved.

Can I use this in Claude Code?

Yes. Claude Code can add the same remote server from the command line or through its MCP configuration — the exact command syntax has changed across versions, so check Claude Code's own MCP documentation for the current one. The server URL is the same either way.

Do I need Claude Pro to add a connector?

Connector features are part of Claude's standard settings, but exact limits by plan can change — check the connectors section in your own Claude settings if you're unsure what your plan allows.

Do I need to reconnect every conversation?

No. Once you add a connector under Settings → Connectors, it's available in new conversations going forward until you remove it.

What this looks like in a conversation

An illustration of the kind of exchange this makes possible, once TradeGauge is connected:

I'm rebuilding. Should I sell CeeDee Lamb now, or hold through his contract situation?

Claude, with TradeGauge connectedCalls get_player_value andget_value_movers, then answers with Lamb's current market value, whether it's trending up or down right now, and what a fair return looks like at that price — instead of a generic take on his situation.
