Overview

AI-generated overview

A remote MCP endpoint offering pay-per-call web utilities: page-to-Markdown conversion, tech stack detection, and email domain checks.

What you can do
This server exposes three web-oriented tools to an assistant: converting a web page into Markdown, identifying the technology stack behind a site, and checking an email domain. Each call is billed individually through the x402 payment scheme in USDC, so the assistant pays per request rather than through a subscription. It runs as a hosted remote endpoint, so there is nothing to install locally.
When to use it
Worth adding when an assistant needs occasional page-to-Markdown extraction, quick tech stack lookups, or email domain checks, and you are comfortable with per-call crypto payments. It is less suitable if you need high-volume scraping or a fixed-cost service.
Requirements
A remote MCP client that supports streamable HTTP, network access to the hosted endpoint, and a funded USDC wallet or payment setup compatible with x402 to cover per-call charges. No API keys, environment variables, or headers are declared.
Before you install
Every tool call costs money in USDC, so usage can spend funds without a fixed cap; review pricing and set limits before connecting an autonomous agent. The service receives the URLs and email domains you submit, which are sent to a third-party host. No authentication is declared, so treat the endpoint as public and avoid sending sensitive targets.

Installation

In SourceWeft

  1. Open x402 Web Tools 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.iparadise71%2Fx402-web-tools/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
