MCP & AI Agents

What is MCP?

Model Context Protocol (MCP) is an open standard that lets AI assistants — like Claude, Cursor, and Windsurf — connect to external data sources and tools. Instead of copying data into a prompt, the AI calls your tools directly and gets live results. With the EventGraph MCP server, any MCP-compatible AI can:

Search live prediction markets across Polymarket, Kalshi, Limitless, and OpinionTrade
Fetch market details, price history, and statistics
Scan for cross-platform arbitrage opportunities
Compare the same event across multiple platforms

Claude Desktop

Connect EventGraph to Claude for live market analysis in conversation

Cursor / Windsurf
