Overview

AI-generated overview

A remote MCP endpoint that offers pay-per-use web extraction, token prices, and wallet balances through x402 USDC micropayments.

What you can do
The server is a hosted streamable HTTP endpoint that exposes web extraction, token price lookup, and wallet balance tools, according to its registry description. Each use is billed as an x402 USDC micropayment rather than through a subscription or API key. No tool list is published in the manifest, so the exact tool names and parameters are not documented here.
When to use it
Consider it when an assistant needs occasional web extraction or token price and wallet balance lookups and you prefer paying per call in USDC instead of managing an API key or subscription. It is less suitable if you need a documented tool list, predictable flat pricing, or offline use.
Requirements
A remote MCP client that supports streamable HTTP, network access to the provider's endpoint, and a funded wallet capable of making x402 USDC micropayments. No environment variables, headers, or authentication are declared in the manifest.
Before you install
Usage is paid: each call settles an x402 USDC micropayment from your wallet, so spending depends on how often the assistant invokes the tools. The manifest declares no authentication, so review how the endpoint identifies and charges your wallet before connecting. Web extraction sends the requested URLs to a third-party service. No tool list is published, so verify behavior before relying on it.

Installation

In SourceWeft

  1. Open x402 Web Extract 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.Senpi-Station%2Fx402-web-extract/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
