Spraay x402 MCP server

Lets your AI look up onchain data, run AI models, and send USDC payments on Base, paying per request.

This is a helper that connects your AI assistant to Spraay, a service that does onchain and payment jobs on the Base network. Once it is connected, your AI can check prices, look up wallet balances, get swap quotes, and even send USDC payments to one or many people. It is handy if you work with crypto payments, payroll, or onchain data and want your AI to handle the lookups and transfers for you.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to Spraay, which runs onchain data lookups and USDC payments on Base. So when you ask your AI to check a token price or send a payment, it uses this helper to talk to Spraay and get the job done.

What this MCP server does

You ask your AI something like what is the price of this token or send 5 USDC to this address. Your AI passes the request to this helper program. The helper talks to the Spraay gateway, which handles the onchain work and the payment. Some jobs are free, and for the paid ones the gateway charges a small amount of USDC from a wallet. Then you get the answer or the confirmation back in your chat.

Flow diagram: you ask your AI “Send 10 USDC to this address”, the Spraay x402 MCP server connects it to Spraay gateway, and you get back answer or payment confirmation.

“Get me a swap quote for 100 USDC to ETH on Base”

What it gives back to you

You get answers in your chat: prices, balances, swap quotes, or lists of transactions. For payments, you get a confirmation that the transfer went through, along with the details. For AI model jobs, you get the text, image, or numbers the model produced. Everything shows up as a normal reply from your AI.

Before you start

What you need

Node.js 20 or newer
An MCP client like Claude Desktop or Cursor
USDC on Base in the wallet the server creates (even $1 covers many calls)

Good to know
