Add Kelly to Grok
Ask Grok about your fantasy team or a bet, and it answers with Kelly’s numbers, each with its source and the time it was true.
Who can’t add it
Kelly isn’t open yet: only Kelly staff can sign in for now, so anyone else’s sign-in is refused. Kelly is for people 21 and older.
xAI’s page says connectors are “available to all Grok users.” On Business and Enterprise plans, a team admin must provision it in the cloud console before members can connect.

Not yet tested with Kelly in Grok. These steps follow xAI’s connectors page as read on Oct 16, 2026.
What you need
A Grok account. On Business and Enterprise plans, a team admin adds it in the xAI console first.
Add it
Open grok.com/connectors and choose New Connector, then Custom.
Name it kelly and paste the server URL.
https://mcp.askkelly.ai/mcpSign in to Kelly when Grok asks, then ask a question in a new chat.
On a Business or Enterprise plan
A team admin opens console.x.ai, then Grok Business, then Connectors, and chooses + Add Connector, then Other.
Name it kelly, paste the server URL, and choose OAuth for sign-in.
https://mcp.askkelly.ai/mcpMembers then open grok.com/connectors, connect kelly and sign in to Kelly.
Your first conversation
Ask in a new chat and name Kelly, so the AI uses Kelly’s tools rather than a web search.
For your fantasy team
Thinking about my fantasy lineup this week. Use Kelly to walk me through it, step by step, starting with what to check first.
For a bet you’re weighing
Looking at a bet on tonight’s game. Use Kelly to walk me through the market, step by step, starting with what to check first.
The first time you sign in
- What signing in creates
- A free Kelly account under the address you sign in with, or your existing account if you have one. The AI gets its own access, which you can end at any time.
- What works at once
- Games, markets, players, explanations and odds maths, each answer with its sources and the time it was true.
- What asks for a step on askkelly.ai
- Confirming you’re 21 or older, which stake tools need, happens once on askkelly.ai; the AI says so when it comes up. Pro tools need a Kelly Pro plan.
Three things to ask first
- Compare two running backs on my roster for this week’s flex spot.
- Answered by
compare_players - What does the no-vig market say about tonight’s spread?
- Answered by
get_market - What implied probability is +150, and what does a $20 ticket pay?
- Answered by
calculate_odds
What it won’t do
- Place a bet, move money or touch a sportsbook account.
- Rank bets or list the day’s top edges. Kelly answers the question you ask.
- Put a stake on Kelly’s own edges.
- Show any one sportsbook’s prices outside askkelly.ai. Through the AI, Kelly gives derived values such as the no-vig line.
- Read your fantasy leagues. Connecting a league isn’t open yet.
What the AI receives from Kelly is held by the AI’s provider, under your account there. Ending Kelly’s access stops new access, but it doesn’t recall what the AI already has.
If it doesn’t work
- Sign-in is refused
- While Kelly isn’t open, only staff accounts can sign in. Otherwise, sign in with the same address you use on askkelly.ai.
- No Kelly tools are listed
- Disconnect Kelly under grok.com/connectors in Grok, then add it again with the server URL above.
- The AI can’t see your own data
- Kelly can’t read your leagues or tickets yet. Ask about games, markets, players and odds instead.
- An answer stops partway
- Long results can be cut short. Ask the AI for the rest.
