Overview

AI-generated overview

A remote MCP endpoint that lets an assistant discover pay-per-call tools and inspect x402 USDC/RLUSD payment requirements before paying.

What you can do
Discover the x402 Gateway contract and where to inspect fresh payment requirements, and check the gateway's public identity and canonical payment rail. Inspect the canonical payment contract, including network, USDC asset, payTo, headers, and the rule for resolving fresh target requirements. The registry description advertises 85+ pay-per-call tools covering trading, federal grants and contracts, SEC filings and FTD data, paid in USDC or RLUSD.
When to use it
Use it when an assistant needs to find x402-paid data or trading tools and check the payment contract and requirements before making a call. Useful for agents that plan autonomous USDC or RLUSD payments.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared, and the manifest declares no authentication. Network access to the hosted endpoint is needed.
Before you install
The advertised tools are pay-per-call, so using them can spend USDC or RLUSD; the exposed tools only inspect payment details, but the broader catalog involves real payments. No authentication is declared, so treat the endpoint as public and unverified.

Installation

In SourceWeft

  1. Open mcp-x402 — MCP server for agents with autonomous USDC/RLUSD payments in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Timwal78%2Fmcp-x402/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
