Paysafe

Overview

Paysafe is a Model Context Protocol (MCP) server: Payment firewall for x402: scans for replay, overpayment, PII/secret leaks, prompt-injection. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package paysafe-x402 speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.1.1.

You'll find Paysafe in the Finance category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
