README
x402-md-mcp
MCP server for webpage → clean Markdown extraction, paid per call in USDC on Base mainnet via the x402 protocol. No API key, no account.
Exposes one tool, extract_markdown(url), which fetches a webpage through the
x402-md service (Mozilla Readability + Turndown),
strips nav/ads/footer, and returns clean Markdown. The $0.005 USDC payment is settled
automatically from your wallet — the server handles the x402 402→sign→retry flow for you.
