### Claude Code
```
请帮我安装 askskill 上的 "SMTP" MCP 服务：
执行：claude mcp add 'io-github-ni-c-smtp-mcp' -- npx -y @ni-c/smtp-mcp
```

### Codex
```
请帮我安装 askskill 上的 "SMTP" MCP 服务：
在 ~/.codex/config.toml 中添加：
[mcp_servers.io-github-ni-c-smtp-mcp]
command = "npx"
args = ["-y","@ni-c/smtp-mcp"]
然后重启 Codex 生效
```

### Cursor
```
请帮我安装 askskill 上的 "SMTP" MCP 服务：
在 .cursor/mcp.json 的 "mcpServers" 中添加：
"io-github-ni-c-smtp-mcp": { "command": "npx", "args": ["-y","@ni-c/smtp-mcp"] }
然后在 Cursor 设置 > MCP 中启用
```
