AI agent access to Asian crypto markets. Korean exchange routing and x402 paid APIs.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
EVM_PRIVATE_KEY, CROSSFIN_API_URL, CROSSFIN_LEDGER_PATH标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

Give your AI agent access to Asian crypto markets. 16 tools for real-time Korean exchange data, cross-exchange routing, and x402 paid API execution across 14 exchanges.
npx -y crossfin-mcp
That's it. Your agent now has 16 tools. Most tools work with no wallet setup, and payment-capable tools require EVM_PRIVATE_KEY.
Open beta note: CrossFin API endpoints are currently free, but payment-capable MCP tools still require wallet config for x402 flow compatibility.
~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": { "crossfin": { "command": "npx", "args": ["-y", "crossfin-mcp"], "env": { "EVM_PRIVATE_KEY": "0x..." } } } }

{
"mcpServers": { "crossfin": { "command": "npx", "args": ["-y", "crossfin-mcp"], "env": { "EVM_PRIVATE_KEY": "0x..." } } } }
.vscode/mcp.json in your project root (or user-level in settings):
{
"inputs": [ { "type": "promptString", "id": "evm-key", "description": "Base wallet private key for x402 payments (optional)", "password": true } ], "servers": { "crossfin": { "type": "stdio", "command": "npx", "args": ["-y", "crossfin-mcp"], "env": { "EVM_PRIVATE_KEY": "${input:evm-key}" } } } }

Paid tools use the x402 protocol for automatic micropayments. When your agent calls a paid endpoint:
402 Payment Required and a price headerEVM_PRIVATE_KEYPayments settle on-chain. Each response includes txHash and a Basescan link for verification. Prices range from $0.01 to $0.20 per call.
To get started, fund a Base wallet with USDC and set EVM_PRIVATE_KEY. No account registration or API keys required.
