概要

What is Piprail?

Piprail is an MCP server that provides any AI agent (Claude Desktop, Cursor, Claude Code, Windsurf, VS Code, Cline) with a budget-capped wallet to autonomously pay x402 ("402 Payment Required") payment-gated URLs. It runs locally with your wallet and a spend policy the model cannot exceed — no backend, no custody, no facilitator, no fee.

How to use Piprail?

Run npx -y @piprail/mcp, add the config block (set your wallet key and spend caps via environment variables like PIPRAIL_MAX_AMOUNT, PIPRAIL_MAX_TOTAL, PIPRAIL_TOKENS, PIPRAIL_HOSTS, and PIPRAIL_CHAIN), then restart your client. The server exposes five tools for discovering, quoting, planning, paying, and registering x402 endpoints.

Key features of Piprail

  • Five tools for the full x402 payment lifecycle.
  • Budget-capped wallet enforced before any on-chain send.
  • Supports every major EVM chain plus Solana, TON, Tron, NEAR, Sui, Aptos, Algorand, Stellar, and XRP Ledger.
  • Works with USDC, USDT, and native coin across chains.
  • Wallet key never leaves your machine — no back end or custody.
  • Runs locally with no facilitator and no additional fee.

Use cases of Piprail

  • AI agents autonomously paying for APIs within a strict budget.
  • Discovering which x402-enabled endpoints are available (
