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.

Install / run

Notes

BUYER_WALLET_PATH

~/.x402-buyer/wallet.json

Target endpoint.

MCP_TRANSPORT

stdio
