Summary
This is a curated subset of xpay's 980+ tool catalog, focused on competitive intelligence work. You get about 40 tools from Brand.dev, Coresignal, Keywords Everywhere, Exa, Firecrawl, and Shofo. It runs on the x402 protocol, so you pay $0.01 USDC per call instead of managing separate API keys for each provider. Connect it to Claude Desktop or any MCP client with your xpay API key, fund your wallet with USDC on Base, and you're set. Useful when you're doing competitor research, market analysis, or brand monitoring and don't want to juggle multiple subscriptions. The payment happens automatically per tool call.

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
Sign up at app.xpay.sh and create an API key. Add credits to your wallet (USDC on Base).
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
