💧 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.

Read Security & Wallet Safety — these tools move real funds.

One-line install (Claude Code)

claude mcp add spraay -s user -- npx -y spraay-x402-mcp

Manual config (Cursor / Claude Desktop)

Cursor (.cursor/mcp.json) or Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "spraay": {
      "command": "npx",
      "args": ["-y", "spraay-x402-mcp"]
    }
  }
}

That's it. The first run prints something like:

💧 Spraay created a new wallet: 0xABC…123
   Private key saved to ~/.spraay/.session (keep it safe — it controls funds).
   Fund this address with USDC on Base to start paying for tool calls.

Optional — bring your own wallet

To sign with a key you already control instead of the auto-created one, set EVM_PRIVATE_KEY in your environment (it overrides the session wallet). Never paste a raw key into a committed config file — use a dedicated hot wallet funded only with what the agent may spend. See Security & Wallet Safety.

Remote URL (no wallet on your machine)

Settlement is handled gateway-side; your client never holds a signing key.
