以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →

MCP server bringing hundreds of x402-paid APIs to AI agents (Claude, Cursor, MCP-aware clients). Auto-discovers tools from CDP Bazaar; handles USDC micropayments on Base + Solana.
Features
- Auto-discovers x402 endpoints from CDP Bazaar (no hard-coded list)
- Reads metadata directly from Bazaar (description, schema, pricing)
- Refreshes every 5 min — new endpoints appear without restart
- Handles HTTP 402 + USDC payment automatically
- Multi-chain: Base + Solana mainnet live (USDC on both); Polygon/BNB/EVM expandable
Install (Claude Desktop)
Add to claude_desktop_config.json:
Set X402_PRIVATE_KEY to a Base EOA private key (hex, 0x-prefixed) with USDC on Base mainnet (Solana payment via SPL USDC also supported). Restart Claude Desktop. The server auto-discovers ~117 tools on first run.
Cost Safety
- Each tool call costs $0.0001-$0.10 USDC depending on endpoint
- Hard cap: MAX_PRICE_USD env var (default $0.10/call); calls above are blocked
- Use a fresh burner wallet, not your main wallet
How it works
Agent calls tool -> HTTP 402 -> x402-fetch signs EIP-3009 -> CDP Facilitator settles on Base or Solana -> response returned. Buyer pays no gas.
