Use Fairline inside Claude

A remote MCP connector that lets your AI assistant shop lines across the books we track and read the model's fair price beside them. Available with a Fairline account and paid plan.

Add it to Claude

Connector URL:

https://mcp.fairline.io/mcp
  1. On claude.ai, open Settings, then Connectors, then Add custom connector, and paste the URL above.
  2. Sign in with your Fairline account and approve the consent screen.
  3. Done. The connector syncs automatically to the Claude iPhone, Android, and desktop apps; adding it once on the web is enough.

Claude Code users can add it from the terminal instead:

claude mcp add --transport http fairline https://mcp.fairline.io/mcp

What your assistant can do

  • get_slate: today's games with every tracked book's price and the best price flagged
  • get_game: the full lines board for one game, including available player props
  • compare_lines: line-shop one market across every tracked book, best price flagged
  • get_model_prices: the model's fair price at every spread and total threshold it prices, not just the projected line
  • get_line_history: how a line moved across the day, book by book
  • get_track_record: the reference model's public calibration record

Every answer leads with actual market prices. The Fairline model appears only as a labeled reference line, never as the headline.

Permissions and safety

The connector signs in as you and sees only your account. All six tools are read-only. None of them writes anything to your account.

Fairline places no wagers and handles no funds, through this connector or anywhere else. You can disconnect at any time from Claude's connector settings, and data your assistant retrieves is handled under its provider's own privacy policy. Details in our Terms and Privacy Policy.
