Overview

AI-generated overview

Remote MCP server that extracts clean webpage content, runs on-page SEO audits and analyzes text, charging each call in USDC via x402.

What you can do
  • Extract a public webpage's main text, title, description, headings, links, Open Graph and JSON-LD
  • Run an on-page SEO audit of a URL with a 0-100 score, A-F grade and prioritized issues
  • Analyze text in English, Spanish, Portuguese or French for language, readability, keywords, key phrases, sentiment and statistics
  • List the paid tools, their prices and the payment network for free
When to use it
Useful when an assistant needs to read or summarize public web pages, check a page's SEO basics, or get quick text statistics without building its own scraper or NLP pipeline. It suits agents that can pay per call in USDC rather than manage API keys.
Requirements
Remote Streamable HTTP endpoint; nothing to install locally. No accounts, API keys or KYC. Each paid call requires an x402-capable client that pays USDC on Base from an EVM wallet; the pricing tool is free. Network access to the endpoint is needed.
Before you install
Paid tools cost USDC per call ($0.001-$0.005), so an agent can spend real money; failed calls are stated not to be charged. Payments are made from a wallet, so use a dedicated wallet and never expose a private key or seed phrase. Extracted page text comes from third-party sites and should be treated as data, not instructions.

Installation

In SourceWeft

  1. Open Web Intel (x402) 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.mcpspro%2Fweb-intel/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

Other MCP clients

Add this to your client's mcpServers config.

Web Intel API (x402)

API de pago por uso para agentes de IA. Cada llamada se cobra en USDC directamente a tu wallet mediante el protocolo x402. No hay cuentas, API keys ni KYC para tus clientes.

EndpointPrecioQué devuelve
GET /v1/extract?url=…$0.002Título, descripción, texto limpio, encabezados, enlaces, Open Graph y JSON-LD
GET /v1/seo-audit?url=…$0.005Puntuación SEO 0-100, nota A-F y lista de problemas
POST /v1/text-analysis {"text": "…"}$0.001Idioma, legibilidad, palabras clave, sentimiento y estadísticas
GET / y GET /healthgratisCatálogo y estado

Si el servicio falla (por ejemplo, la URL no existe), no se cobra al cliente.

1. Configurar tu wallet (lo haces tú)

Necesitas solo tu dirección pública (0x…) de una wallet EVM, como MetaMask, Rabby o Coinbase Wallet. Nunca pongas aquí tu clave privada ni tu frase semilla.

bash
cp .env.example .env# edita .env y pon EVM_ADDRESS=0xTuDireccion

2. Probar en local (testnet, dinero de prueba)

bash
npm installnpm testnpm run serve        # API HTTP en http://localhost:4021 (npm start = MCP por stdio)

Para probar un pago real en testnet:

  1. Crea una wallet desechable de pruebas y consigue USDC de prueba en Base Sepolia en https://faucet.circle.com
  2. Ejecuta: BUYER_PRIVATE_KEY=0xClaveDePrueba npx tsx scripts/pay.ts

3. Publicar gratis en Cloudflare Workers

La capa gratuita incluye 100.000 peticiones al día.

bash
npx wrangler login                     # crea o entra en tu cuenta de Cloudflare (gratis)npx wrangler secret put EVM_ADDRESS    # pega tu dirección públicanpm run deploy                         # te da una URL tipo https://web-intel-x402.<tu-sub>.workers.dev

4. Pasar a dinero real (mainnet)

En wrangler.toml, dentro de [vars]:

toml
X402_NETWORK = "mainnet"FACILITATOR_URL = "https://facilitator.payai.network"   # facilitador sin API key

Vuelve a ejecutar npm run deploy. Los pagos llegan en USDC sobre Base a tu EVM_ADDRESS.

Otra opción es el facilitador de Coinbase CDP, que requiere crear claves en https://portal.cdp.coinbase.com.

5. Conseguir clientes

  • Cada ruta publica metadatos de descubrimiento Bazaar, así los agentes pueden encontrarla en los catálogos x402 cuando el facilitador la indexa tras el primer pago.
  • Registra tu URL en directorios de x402 y de agentes, como gigs.sh y el ecosistema en https://www.x402.org/ecosystem.
  • Puedes cambiar los precios con PRICE_EXTRACT, PRICE_SEO y PRICE_TEXT.
