Dino Markets MCP is a Model Context Protocol server that bridges Kalshi and Polymarket prediction market data, enabling AI agents (Claude, Cursor) to scan for cross-venue arbitrage opportunities. The repo provides 8 tools that match equivalent markets across both platforms—such as 'Will BTC be above $100K by date X' appearing on both exchanges—then compares spreads and order book depth to identify profitable discrepancies. The implementation uses JavaScript and is minimal (17KB), suggesting a thin wrapper around both APIs with matching logic rather than a full trading bot. The MCP integration is particularly clever: it allows LLMs to dynamically query market data and make trading decisions, potentially enabling fully automated cross-venue strategies. The matched-market approach is the holy grail of prediction market arbitrage, as Kalshi and Polymarket often list identical event contracts with diverging prices due to different user bases and liquidity profiles. The repository is brand new (created today, July 23, 2026), so code maturity is uncertain, but the concept is strong. For developers building AI trading agents, this MCP server provides a clean integration point. The primary risk is that matched-market identification is non-trivial—markets use different naming conventions and resolution criteria—so the matching accuracy needs validation. Worth cloning to inspect the matching logic and contribute improvements. Ideal for algorithmic traders comfortable with MCP and TypeScript/JavaScript ecosystems.
