Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account ihen404 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A remote MCP endpoint for agent-driven web scraping that pays $0.02 USDC per request over the x402 protocol on Base, returning clean Markdown.

What you can do: Fetch a web page through an x402-paid scraping request and get back token-optimized Markdown with HTML and navigation boilerplate stripped.
Discover and settle per-request payments in USDC on Base mid-task, without API keys.
Queue scraping jobs through a decoupled worker setup intended to hold up under concurrency.
Register or identify the agent on-chain via ERC-8004 identity on Base Mainnet or Base Sepolia.
When to use it: Use it when an agent needs to scrape pages without managing API keys or proxy subscriptions, and you are comfortable paying a flat per-request fee in USDC from a wallet. It suits autonomous agent workflows on Base rather than one-off manual fetching.
Requirements: A remote MCP endpoint (the manifest points at a placeholder domain, so a real deployment URL is needed). A funded crypto wallet with USDC on Base Mainnet or Base Sepolia, plus Coinbase AgentKit and LangChain packages if you follow the README's agent setup. Network access to the endpoint and the Base network.

Before you install

Every request spends real money: a flat $0.02 USDC settlement per scrape, signed from a wallet the agent controls. The wallet and its keys are the main risk, and autonomous payment without confirmation can drain funds. Scraped content is fetched from third-party sites, and the README's MCP URL points to a raw GitHub file rather than a hosted server.

Installation

In SourceWeft

Open X402 Scraper in the dashboard and add it to a workspace.
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.ihen404%2Fx402-scraper/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

README

@ihentrel/x402-scraper-langchain

[npm version] [License: MIT] [Network]

Protocol-native web scraping utility tool engineered for autonomous AI agents, powered by Coinbase AgentKit, LangChain, and x402 on-chain micro-settlements.

Key Features & Strategic Positioning

Zero API Keys Required: Agents discover, pay, and execute scraping requests mid-task without unhandled API key exceptions or rate limits.
Predictable Operational Cost: Flat $0.02 USDC/request settlement on Base, offering a transparent OpEx alternative to dynamic per-gigabyte proxy services.
Token-Optimized Markdown: HTML, navigation boilerplate, and DOM elements are automatically stripped into clean, token-dense Markdown to reduce LLM context window costs.
Asynchronous Queue Resilience: Underpinned by a decoupled better-sqlite3 queue and PM2 worker mesh to prevent payload failures under high concurrency.
Ecosystem Ready: Native support for Model Context Protocol (MCP) manifests (/mcp.json) and ERC-8004 identity registration on Base.
