ParlayWhat is Parlay
Parlay is an MCP server that connects AI assistants to prediction markets. Ask Claude, ChatGPT, Gemini, or any MCP-compatible client to research, compare, and forecast across Polymarket, Kalshi, Limitless, and Manifold — no dashboards, no learning curve.
One schema, every venue

Every venue, one call
Query Polymarket, Kalshi, Limitless, and Manifold through one tool schema. Ask for comparisons when you need cross-venue analysis.
Built to inform, not to trade
