X402 Middleware

A local stdio MCP package that adds x402 and Stripe payment middleware to MCP servers, positioning itself as payment infrastructure for the agent economy.

What you can do

The listing gives no tool list, so capabilities are described from the short registry text only. It is described as one-line x402 plus Stripe payment middleware for MCP servers, meaning it is meant to sit in front of or alongside an MCP server to handle payments. It is framed as payment infrastructure for the agent economy. No further functions, endpoints or configuration options are documented in the supplied material.

When to use it

Consider it only if you are building or operating an MCP server and want to add x402 and Stripe payment handling to it. It is not aimed at end users looking for general assistant tools, since no tools are listed.

Requirements

Runs as a local process over stdio, installed from the npm package @gadgethumans/x402, so a Node.js runtime is needed. The manifest declares no authentication, environment variables or headers, but the description names Stripe, so a Stripe account or credentials would likely be needed; this is not confirmed by the input. Desktop only.
