MEOK x402 Wrap MCP

🧱 Part of the MEOK A2A Substrate (£999/mo)
See meok.ai/a2a.

1-line USDC paywall for any FastMCP tool

What this does

Coinbase x402 = HTTP 402 + on-chain settlement. ~165M agent transactions through the protocol as of May 2026; moved to Linux Foundation Sept 2025. Coinbase + Cloudflare + Vercel all ship examples but nobody ships a universal wrapper.

This MCP gives you exactly that — one decorator turns any FastMCP tool into a pay-per-call endpoint settled in USDC on Base / Polygon / Solana or BTC on Lightning.

from meok_x402_wrap import x402

@x402(price_micro_usd=5000, chains=["base"], receiver="0xYourAddress")
@mcp.tool()
def my_pay_per_call_tool(arg: str) -> dict:
