x402-gated web scraping MCP server. Pay 0.01 USDC per page on Base. Returns clean Markdown via JSDOM
Aetheris MCP server exists for a simple reason — assistants are far more useful when they can act on Aetheris directly instead of describing what you should do. x402-gated web scraping MCP server. Pay 0.01 USDC per page on Base. Returns clean Markdown via JSDOM.
Bring Your Own Key (BYOK) for inference. Settle in USDC on Base for context.
Installation goes through your MCP client rather than a global install: point it at @aetheris/mcp-client on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Once Aetheris is connected, these are the calls the assistant has available:
Engine — ** Node.js + ExpressScraper — ** JSDOM (Deep DOM sanitization, strips scripts/styles/ads)Transport — ** Server-Sent Events (/sse & /message)Monetization — ** ethers.js (EVM HTTP 402 validation on Base Mainnet)USDC_CONTRACT_ADDRESS — The target ERC-20 contractMERCHANT_WALLET_ADDRESS — Your EVM public keyRPC_URL — Your Web3 RPC provider (defaults to https://mainnet.base.org)Among the search and retrieval options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Aetheris's toolset — Engine, Scraper, Transport and 4 more — is a fair guide to whether it matches your workflow. It is maintained by Timwal78; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
