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": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json
{
  "mcpServers": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "reddit-mcp-buddy-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json
{
  "context_servers": {
    "reddit-mcp-buddy-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/karanb192/reddit-mcp-buddy"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add reddit-mcp-buddy-2 -- TODO 'See README: https://github.com/karanb192/reddit-mcp-buddy'

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