Setup snapshot

git clone https://github.com/plagtech/spraay-x402-mcp.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Spraay x402 MCP Server

MCP server for Spraay x402 Gateway — connect Claude, Cursor, or any MCP-compatible AI to onchain data, AI models, and batch payments on Base.

AI agents pay USDC per request. No API keys. No accounts. Just plug in and go.

9 Tools Available

| Tool | Cost | What It Does | | --- | --- | --- | | spraay_chat | $0.005 | AI chat via 200+ models (GPT-4, Claude, Llama, Gemini) | | spraay_models | $0.001 | List available AI models with pricing | | spraay_batch_execute | $0.01 | Batch payments — any ERC-20 token + native ETH | | spraay_batch_estimate | $0.001 | Estimate costs for batch payments | | spraay_swap_quote | $0.002 | Uniswap V3 swap quotes on Base | | spraay_tokens | $0.001 | List supported tokens on Base | | spraay_prices | $0.002 | Live onchain token prices (Uniswap V3) | | spraay_balances | $0.002 | ETH + ERC-20 balances for any address | | spraay_resolve | $0.001 | Resolve ENS names and Basenames to addresses |

Quick Start

1. Clone and Install

git clone https://github.com/plagtech/spraay-x402-mcp.git
cd spraay-x402-mcp
npm install
npm run build

2. Configure Claude Desktop

Add to your Claude Desktop config:

{
  "mcpServers": {
    "spraay": {
      "command": "node",
      "args": ["/absolute/path/to/spraay-x402-mcp/dist/index.js"],
      "env": {
        "EVM_PRIVATE_KEY": "0xYourPrivateKeyWithUSDCOnBase"
      }
    }
  }
}

3. Configure Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "spraay": {
      "command": "node",
      "args": ["/absolute/path/to/spraay-x402-mcp/dist/index.js"],
      "env": {
        "EVM_PRIVATE_KEY": "0xYourPrivateKeyWithUSDCOnBase"
      }
    }
  }
}

4. Restart and Use

Restart Claude Desktop or Cursor. Then just ask:

  • "What is the current price of ETH on Base?" → calls spraay_prices
  • "Check the USDC balance of vitalik.eth" → calls spraay_resolve then spraay_balances
  • "Get me a swap quote for 100 USDC to WETH" → calls spraay_swap_quote
  • "Send 10 USDC each to these 5 addresses" → calls spraay_batch_execute
  • "Spray 0.01 ETH to 50 wallets" → calls spraay_batch_execute with ETH

Environment Variables

| Variable | Required | Description | | --- | --- | --- | | EVM_PRIVATE_KEY | Yes | Private key of a wallet with USDC on Base mainnet | | SPRAAY_GATEWAY_URL | No | Gateway URL (default: https://gateway.spraay.app) |

How Payments Work

You ask Claude -> Claude calls spraay_batch_execute tool
                        |
            MCP server hits gateway.spraay.app/api/v1/batch/execute
                        |
            Gateway returns HTTP 402 + payment requirements
                        |
            x402 client auto-signs $0.01 USDC payment
                        |
            Retries request with payment proof
                        |
            Gateway verifies payment, returns batch calldata
                        |
            Claude shows you the transaction data

Your wallet pays USDC on Base for each tool call. Payments are instant and verifiable onchain.

Supported Batch Payment Tokens

Spraay supports any ERC-20 token and native ETH on Base. Use token symbols or contract addresses:

  • USDC — USD Coin
  • USDT — Tether
  • DAI — Dai
  • EURC — Euro Coin
  • ETH — Native Ether
  • Any ERC-20 contract address (0x...)
