Claude and prediction markets — frequently asked
What if I cannot find “Add custom connector” in Claude?
Anthropic decides which plans and workspaces can add custom connectors, and on Team and Enterprise an owner may have to allow them first. If the option is missing, ask your workspace owner, or use Claude Code, which adds the server from the terminal with the command above.
Does Claude Code need anything besides the one command?
No. The command registers the server over Streamable HTTP; there is no package to install and no key to export. Restart the session if the tools do not appear, then ask about a market.
What can Claude answer once the connector is on?
Live prices and probabilities: NFL props venue by venue, NBA game lines, props and injury impact, the NHL Goal Light board, Kalshi high-temperature strikes in 13 cities, strike ladders, win probability, Fed and election odds, cross-venue price gaps, the 15-minute and perpetual boards, plus expected-value, Kelly and Bayesian calculators. 38 tools are free; Pro adds the model’s edge calls.
Does the connector see my Claude conversations?
It only receives the arguments of the tool Claude decides to call — for example a player name or a market ticker — and returns market data. It never receives the rest of the chat.
