🛡️ Aetheris-MCP: The x402 Agentic Web Scraper

Render Model Context Protocol Base

Aetheris-MCP is an enterprise-grade Server-Sent Events (SSE) Model Context Protocol server. It provides AI Agents with high-fidelity, ad-free Markdown web scraping capabilities, protected by an on-chain x402 Micropayment Interceptor.

Bring Your Own Key (BYOK) for inference. Settle in USDC on Base for context.

🏗️ Architecture

  • Engine: Node.js + Express
  • Scraper: JSDOM (Deep DOM sanitization, strips scripts/styles/ads)
  • Transport: Server-Sent Events (/sse & /message)
  • Monetization: ethers.js (EVM HTTP 402 validation on Base Mainnet)

🚀 One-Click Deployment

This repository is configured with a render.yaml Blueprint.

  1. Fork this repository.
  2. Go to your Render Dashboard.
  3. Click New -> Blueprint.
  4. Connect the forked repository. Render will automatically detect the configuration and deploy the Express server.

⚙️ Environment Variables

Ensure you set these in your hosting environment:

  • REQUIRE_PAYMENT (boolean) - Enforces the 402 interceptor.
  • BASE_MICROPAYMENT_COST (float) - USDC cost per scrape (e.g., 0.01).
  • USDC_CONTRACT_ADDRESS - The target ERC-20 contract.
  • MERCHANT_WALLET_ADDRESS - Your EVM public key.
  • RPC_URL - Your Web3 RPC provider (defaults to https://mainnet.base.org).

💻 Client Integration

Agents should NOT connect to this server manually. Use the official Auto-Settlement SDK: npm install @aetheris/mcp-client

See the Client SDK Repository for documentation on how the SDK intercepts the 402 challenge and settles the transaction autonomously.
