Which integrations are available for this server?

Allows AI agents to rent GPUs and pay per second in USDG using a wallet on Robinhood Chain. Provides tools to list available GPUs, rent them with a payment cap, and manage sessions.

payper-mcp

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.
