Flipcoin

Overview

Flipcoin is a Model Context Protocol server that brings agent-first prediction markets on Base directly into your AI assistant. You can trade, quote, and create markets through MCP, giving AI models the ability to interact with prediction market functionality as native tools.

The server runs locally on your machine using the npm package @flipcoin/mcp-server, communicating over stdio. You'll need to provide your FLIPCOIN_API_KEY via environment variable to authenticate. The latest release is v0.1.2, and the full source code is available at flipcoin-fun/flipcoin-mcp on GitHub.

Flipcoin is listed in the AI & Agents category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP-compatible clients. If you maintain Flipcoin, you can claim this listing to verify your ownership and keep the information up to date.
