Pay Mcp

Overview

Pay Mcp is a Model Context Protocol server that brings x402 payment tools directly into your AI assistant. It lets you pay, verify STARK receipts, and hash data per RFC 8785—all without requiring an account. The server exposes these capabilities as tools that Claude, Cursor, VS Code, and other MCP clients can invoke on your behalf.

The server runs entirely on your local machine. Install it with npx -y @vauban-org/pay-mcp and authenticate using your API Key. It communicates with your client over stdio, and the latest release is v0.2.2.

Pay Mcp is listed in the Finance category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Pay Mcp, claim this listing to verify ownership and keep the information current.
