Claude MCP x402 Integration
Claude's Model Context Protocol (MCP) represents the cutting edge of AI-system integration. MCP allows Claude to natively connect with external tools, databases, and services through a standardized protocol. For x402 integration, MCP offers the most seamless experience with native protocol support, making payment operations feel like natural extensions of Claude's capabilities.

Examples
Installation & Setup
Install the necessary packages to get started with x402 payments in Claude MCP:
# Install the necessary packages npm install claude mcp x402-claude mcp
The x402-claude mcp package is a helper library that simplifies wrapping facilitators into Claude MCP-compatible tools, bridging our facilitator ecosystem with your agent framework.
Integration Examples
x402 MCP Server
Create a dedicated MCP server that exposes x402 payment capabilities to Claude through the native protocol
import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { X402Client } from 'x402-client';
const server = new Server({
name: 'x402-mcp-server',
version: '1.0.0'
});
server.setRequestHandler('tools/call', async (request) => {
if (request.params.name === 'x402_payment') {
const { amount, recipient } = request.params.arguments;
const client = new X402Client();
return await client.sendPayment(amount, recipient);
}
});Prerequisites:
Claude API access
MCP SDK installation
x402 client library
Choosing Your Facilitator
The X402PaymentTool is generic and works with any facilitator that has a compatible client. Here's how you might initialize different clients based on your specific needs:
For Enterprise (CDP)
import { CDPClient } from 'x402-facilitators';
const client = new CDPClient({ apiKey: "..." });See the CDP Facilitator Guide for details.
For Zero Fees (Mogami)
import { MogamiClient } from 'x402-facilitators';
const client = new MogamiClient({ walletPk: "..." });See the Mogami Facilitator Guide for details.
For Developer Experience (thirdweb)
import { ThirdwebClient } from 'x402-facilitators';
const client = new ThirdwebClient({ secretKey: "..." });See the thirdweb Facilitator Guide for details.
Custom Setup
// Use any facilitator from our hub
import { CustomClient } from 'x402-facilitators';
const client = new CustomClient({ config: "..." });Browse all 8 facilitators in our hub.
