Mcp X402

Overview

Mcp X402 is an MCP server that brings Coinbase's x402 HTTP-native micropayments protocol into your AI workflows. Any MCP-compatible AI assistant can call its tools directly, letting the model decide when to execute micropayments on USDC across Base and Solana networks within conversations and agent runs.

The server runs locally via the npm package @codespar/mcp-x402, communicating over stdio. Installation is simple: npx -y @codespar/mcp-x402. You'll need to provide an X402_API_KEY environment variable to authenticate. The latest release is v0.1.4, published under the MIT license with source code available at codespar/mcp-dev-latam on GitHub, where the project has attracted 269 stars.

Mcp X402 is categorized under AI & Agents on mcp.site and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim this listing to verify ownership, earn the Verified badge, and keep information up to date.
