💧 Spraay x402 MCP Server
Full-stack DeFi infrastructure for AI agents — 183 pay-per-call tools, backed by the 192-endpoint Spraay x402 Gateway on Base, with Solana, Ethereum, XRP, and Stellar payment rails.
Connect Claude, Cursor, or any MCP client to onchain payments, batch payouts, swaps, bridging, payroll, invoicing, escrow, oracle data, analytics, 200+ AI models, GPU/compute, research APIs, search/RAG, and more. Agents pay USDC per request via the x402 protocol — no API keys, no accounts.
The tool list is generated from the live gateway manifest at build time (
npm run sync), so the authoritative catalog and pricing always live at the gateway — see Tool catalog. 24 of the gateway's endpoints are free (no payment required).
Quick Start
Install and go — no config, no API keys, no env vars. On first run the
server auto-creates a wallet, saves it to ~/.spraay/.session, and prints the
address to stderr. Fund that address with USDC on Base and start calling tools.
