AI-native intelligence layer for prediction markets. Parlay is a hosted MCP server that brings live prediction market data into Claude, ChatGPT, Gemini, and other MCP clients. Search and compare event contracts across Polymarket, Kalshi, and Limitless (real-money venues) with Manifold isolated as a sentiment-only signal. Six tools: search_markets, market_brief, discover_markets, compare_markets, scan_discrepancies, inspect_platform. Every response carries unified metadata — data freshness, match confidence, liquidity status, and risk flags. Read-only by design: no order placement, no fund custody, no venue API keys required. PMXT-backed real-money data layer. Free tier: 15 calls/month. Pro: $29/mo for 150 calls. Streamable HTTP transport at https://mcp.parlay.run/mcp.
