Add Kelly to Claude

Ask Claude 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.

On Team and Enterprise plans, Anthropic’s help page says only Owners and Primary Owners can add one, so members ask an Owner (below).

Not yet tested with Kelly in Claude. These steps follow Anthropic’s help page as read on Oct 16, 2026.

What you need

A Claude plan: Free, Pro, Max, Team or Enterprise. Add it on the web or in Claude Desktop; it then works in Claude’s mobile apps too. On Team and Enterprise plans, an Owner adds it.

Add it

Open Customize, then Connectors, and choose Add custom connector.
Name it kelly, paste the server URL as the MCP server URL and choose Continue. Leave sign-in and the OAuth client as Claude detects them, with Use Claude’s published identity, and choose Add.
https://mcp.askkelly.ai/mcp/cards
Choose Connect and sign in to Kelly. In a new chat, turn Kelly on under +, then Connectors, and ask a question.

Some accounts reach the form through + Add, then Add custom connector, and some see one form instead of two steps: fill in the same fields and choose Add.

On a Team or Enterprise plan

An Owner opens Organization settings, then Connectors, and chooses Add, then Custom. If Claude asks for the connector type, choose Web.
Name it kelly, paste the server URL, and choose Add.
https://mcp.askkelly.ai/mcp/cards
Each member opens Customize, then Connectors, finds kelly with the Custom label, and chooses Connect.

On Enterprise, a custom role with Manage access to Libraries can add it too.

On your phone

Once it’s added on the web or in Claude Desktop, Kelly works in Claude’s mobile apps.

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.

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 Customize, Connectors in Claude (choose Remove, or the three-dot menu), 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.
