python-MCPServer拉取和使用部署

news 2025/11/15 9:09:17

系统环境

系统 macOS 26.0.1
本次学习使用的项目

环境搭建

虚拟环境搭建

cd pyworkspace/news_server
uv venv
uv init

创建一个虚拟环境以后，手动安装fastmcp，原项目中使用 mcp-server-fastmcp,依赖找不到，可能是变更了。目前使用如下方式可以解决

uv add fastmcp# 清理 requirements.txt 中的问题包
sed -i '/mcp-server-fastmcp/d' requirements.txt  # Linux/Mac
# 或手动编辑文件 ，删除requirements.txt  中的mcp-server-fastmcp并保存文件
# 安装依赖
uv pip install -r requirements.txt
# 查看依赖结果
uv pip list

本地启动

点开 Server.py文件，替换 mcp.run(transport="streamable-http") 本地启动测试；更推荐作为服务使用参考该文档不同传输模式对比

在这里插入图片描述

docekr 部署

当前项目需要修改的点如下,修改的目的，docker 中部署指定 host 和 port
server.py 中
1.
mcp = FastMCP("NewsServer", host="0.0.0.0", port=8000)
2.

    # 使用stdio传输# Bind to 0.0.0.0 so the service is reachable from outside the container# and ensure it listens on port 8000 (the container's exposed port).# FastMCP.run forwards args to the underlying ASGI server (uvicorn),# so passing host/port here makes the containerized service accessible.try:mcp.run(transport="streamable-http", host="0.0.0.0", port=8000)except TypeError:# If the FastMCP.run implementation doesn't accept host/port keyword args,# fall back to the default call so the module still runs.mcp.run(transport="streamable-http")
