Nory MCP Server

Give any AI agent the ability to pay.

The Nory MCP Server enables AI agents and assistants to make instant micropayments using the x402 protocol. Built for the future where AI agents are consumers.

What is this?

This is a Model Context Protocol (MCP) server that gives AI assistants like Claude the ability to:

• Check wallet balances
• Make direct payments
• Access paid APIs with automatic x402 payment handling
• Discover x402-enabled services
• View payment history

How x402 Works

1. Request - Agent makes HTTP request to x402-enabled endpoint
2. 402 Response - Server returns HTTP 402 with payment details
3. Payment - Agent creates signed transaction via Nory
4. Settlement - Transaction confirmed on Solana in < 1 second
5. Access - Agent retries request with payment proof, gets response

All of this happens automatically when you use nory_x402_request.

Example Usage

Access a paid API

User: "Use Nory to get the latest crypto prices from the premium data feed"

[Calls nory_x402_request with url="https://api.noryx402.com/data/crypto"]

Result: Successfully paid 0.0001 USDC and received the data...

Check balance before a task

User: "Before we start, check how much I have in my Nory wallet"
