xpay MCP Server

980+ AI tools available as MCP servers. Pay $0.01/call in USDC via the x402 protocol. One API key, 30+ providers — no individual provider accounts or subscriptions needed.

Quick Start

1. Get your API key

2. Add to your MCP client

Claude Desktop / Cursor / Windsurf — add to your MCP config:

{
  "mcpServers": {
    "xpay": {
      "url": "https://mcp.xpay.sh/mcp?key=YOUR_API_KEY"
    }
  }
}

Claude Code CLI:

claude mcp add --transport http "xpay" "https://mcp.xpay.sh/mcp?key=YOUR_API_KEY"

Replace YOUR_API_KEY with your key from step 1.

3. Use tools

Your AI assistant will automatically discover all available tools. Each tool call costs $0.01 USDC, deducted from your wallet balance.

How It Works

Get a key — Sign up at app.xpay.sh and add USDC credits
Connect — Add the endpoint URL (with your key) to any MCP client
Call tools — Your AI assistant discovers and calls tools naturally
Auto-deduct — Each call costs $0.01 USDC, deducted from your wallet balance

No individual provider API keys. No separate accounts. One key for 30+ providers.

Requirements

API key from app.xpay.sh
USDC credits in your xpay wallet (add via Coinbase)
MCP client — Claude Desktop, Cursor, Windsurf, Claude Code CLI, Cline, etc.

How x402 Works

x402 is an open protocol for machine-to-machine payments using HTTP 402 Payment Required. When a tool call requires payment:

Server responds with 402 Payment Required + a payment invoice
Client signs a USDC payment on Base blockchain
Server verifies payment and executes the tool
Settlement is instant, non-custodial, and peer-to-peer
