Let any MCP-capable AI agent rent real GPUs and pay per second in USDG over
x402 on Robinhood Chain — one wallet, no account, no KYC.
Add it to your agent
Works with Claude Desktop, Claude Code, Cursor, Cline, or any MCP client. Add:
{
"mcpServers": {
"payper": {
"command": "npx",
"args": ["-y", "payper-mcp"],
"env": {
"PAYPER_WALLET_KEY": "0xYOUR_WALLET_PRIVATE_KEY",
"PAYPER_GATEWAY": "https://app.payperlabs.com"
}
}
}
}
PAYPER_WALLET_KEY is a wallet that holds USDG on Robinhood Chain (chain 4663).
It signs payments (gasless — Payper pays the gas). Use a dedicated agent wallet,
not your main one, and keep only what you want the agent to be able to spend.
Tools
| Tool | What it does |
|---|---|
| list_gpus | Live catalog of GPUs + per-hour USD prices |
| rent_gpu(gpu, maxUsd) | Rent one. Signs a USDG payment up to maxUsd, returns an access code + connection details. You're charged only for seconds used. |
| check_session(code) | State, connection details, and spend for a session |
| stop_session(code) | Stop and refund the unused USDG automatically |
How it works
rent_gpu runs the whole x402 flow for the agent: it requests a GPU, receives
an HTTP 402 with the price, signs one EIP-3009 authorization for the cap
(gasless), and retries. The unused balance is refunded on stop_session. No
account, no card, no invoice — just a wallet.
