MCP-NTP 时间服务
这是一个基于MCP（Model Context Protocol）的NTP时间服务，为大模型提供准确的网络时间获取功能。
功能特性
- 从NTP服务器获取准确的网络时间
- 支持stdio和sse两种传输模式
- 提供
get_current_time工具，方便大模型获取当前时间 - 支持环境变量和请求头两种配置NTP服务器的方式
- 返回详细的时间信息和NTP协议数据
安装
# 使用 uv 安装依赖
uv sync
配置
环境变量配置（stdio模式）
设置NTP_DOMAIN_URL环境变量：
export NTP_DOMAIN_URL="ntp.aliyun.com"
请求头配置（sse模式）
在请求头中包含ntp_url字段：
ntp_url: ntp.aliyun.com
使用方法
stdio模式
# 设置环境变量
export NTP_DOMAIN_URL="ntp.aliyun.com"
# 启动服务
python -m app
sse模式
# 启动服务
python -m app --transport sse --port 8080
# 使用curl测试
curl -H "ntp_url: ntp.aliyun.com" http://localhost:8080/sse
工具说明
get_current_time
获取当前NTP服务器时间。
参数：
ntp_server(可选): NTP服务器地址，如果不提供则使用环境变量或请求头中的配置
返回数据：
{
"ntp_server": "ntp.aliyun.com",
"ntp_timestamp": 1703123456.789,
"ntp_time": "2023-12-21T10:30:56.789",
"local_system_time": "2023-12-21T10:30:56.789",
"time_offset": 0.123,
"response_delay": 0.045
}
调试
可以使用提供的测试NTP服务器进行调试：
export NTP_DOMAIN_URL="ntp.aliyun.com"
python -m app -v
