This MCP server lets Claude Desktop automatically handle web requests that require Solana-based payments. It fetches data from URLs and processes X402 payments when needed, enabling seamless pay-as-you-go access to protected resources while tracking balance, payments, and spending limits.

How to use

You interact with the MCP server through your Claude Desktop assistant. When you request data from a URL that requires payment, Claude automatically handles the X402 payment flow and retries the request once payment is made. You can fetch public data, post data, check your balance, view payment history, and set spending limits all within natural language conversations.

When a request needs payment

If a target endpoint enforces payment, the service returns a 402 status. Claude then initiates an automatic payment using your Solana wallet and retries the request with proof of payment. This makes paid data access smooth and hands-free.

Examples of common interactions

Fetch data from a URL without showing payment details in your workflow. Claude handles the payment behind the scenes and returns the data.

Fetch data from a paid service and receive the premium data after the payment is processed.

How to check balance and manage limits

Ask for your current SOL balance to see how much is available for payments and how much you have spent in total.

Set a maximum spending limit per request to prevent overspending. You can lower or remove the limit by setting it to 0.
