X402 Api

Overview

X402 Api is a Model Context Protocol server that connects AI agents to DeFi data through a pay-per-call model using x402 tokens and USDC on Base. Instead of manually fetching blockchain data, your AI assistant can call X402 Api as a native tool, accessing real-time DeFi information directly within supported MCP clients.

The server runs locally on your machine via the npm package @x402-api/mcp-server. Installation is straightforward with npx -y @x402-api/mcp-server, and no authentication credentials are required—it works immediately after install. Version v1.0.2 is available now under the MIT license, with full source code hosted at fernsugi/x402-api-mcp-server on GitHub.

X402 Api belongs 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. If you maintain this server for fernsugi, claim this listing to verify ownership and keep the information accurate.
