Arena Predictions

Overview

Arena Predictions is an MCP server that lets your AI agent paper trade prediction markets at live prices and automatically score every trade. By integrating with the Model Context Protocol, it turns prediction market trading into a set of callable tools that AI assistants can use directly, without switching between apps or manual data entry.

The server runs locally on your machine via the npm package arena-mcp-server, installed with npx -y arena-mcp-server. No authentication or credentials are needed—it works immediately after installation. The latest release is v0.5.0. You can find full documentation at https://arena-predictions.com/docs/mcp.

Arena Predictions is listed in the AI & Agents category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed.
