安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "paypal-agent-toolkit-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@paypal/agent-toolkit",
        "mcp"
      ]
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "paypal-agent-toolkit-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@paypal/agent-toolkit",
        "mcp"
      ]
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "paypal-agent-toolkit-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@paypal/agent-toolkit",
        "mcp"
      ]
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "paypal-agent-toolkit-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@paypal/agent-toolkit",
        "mcp"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "paypal-agent-toolkit-mcp",
      "command": "npx",
      "args": [
        "-y",
        "@paypal/agent-toolkit",
        "mcp"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "paypal-agent-toolkit-mcp": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "@paypal/agent-toolkit",
          "mcp"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add paypal-agent-toolkit-mcp -- npx -y @paypal/agent-toolkit mcp

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： PayPal Agent Toolkit

Send an invoice to a freelance client from a conversation

👤 Solo operators, freelancers ⏱ ~15 min intermediate

何时使用： Client just confirmed scope in chat — you want the invoice out before context-switching.

前置条件

步骤

→ Invoice id + payment link
Confirm and send

Send the invoice now and tell me the URL to copy into email.✓ 已复制

→ Sent status + URL

结果： Invoice issued in 30 seconds without leaving the chat.

注意事项

Always start in sandbox. Live mode is one env var away from being real money. Set PAYPAL_ENVIRONMENT=sandbox until you've tested the exact f — Always start in sandbox. Live mode is one env var away from being real money. Set PAYPAL_ENVIRONMENT=sandbox until you've tested the exact flow.
