MCP-YNU - FastMCP 服务器
使用 FastMCP 的动态 MCP 服务器实现，可自动从相应目录加载工具、资源和提示。
特征
从
tools/、resources/和prompts/目录动态加载模块自动发现和注册模块
简单的配置和可扩展性
类型提示可提高代码清晰度和静态分析能力
用于监控服务器活动的综合日志记录
最近更新
在整个代码库中添加了类型提示
改进了 MCP 实例处理
增加了日志记录功能
添加 MIT 许可证
更新了带有参考链接的文档

用法
在适当的目录中创建模块
通过
from mcp_server import mcp运行服务器：
python main.py
示例模块
工具模块示例（tools/example.py）
from mcp_server import mcp
import httpx
@mcp.tool()
def calculate_bmi(weight_kg: float, height_m: float) -> float:
"""Calculate BMI given weight in kg and height in meters"""
return weight_kg / (height_m**2)
@mcp.tool()
async def fetch_weather(city: str) -> str:
"""Fetch current weather for a city"""
async with httpx.AsyncClient() as client:
response = await client.get(f"https://api.weather.com/{city}")
return response.text
资源模块示例（resources/example.py）
from mcp_server import mcp
@mcp.resource("config://app")
def get_config() -> str:
"""Static configuration data"""
return "App configuration here"
@mcp.resource("users://{user_id}/profile")
def get_user_profile(user_id: str) -> str:
"""Dynamic user data"""
return f"Profile data for user {user_id}"
提示模块示例（prompts/example.py）
from mcp_server import mcp
from mcp.server.fastmcp.prompts import base
@mcp.prompt()
def review_code(code: str) -> str:
return f"Please review this code:\n\n{code}"
@mcp.prompt()
def debug_error(error: str) -> list[base.Message]:
return [
base.UserMessage("I'm seeing this error:"),
base.UserMessage(error),
base.AssistantMessage("I'll help debug that. What have you tried so far?"),
]
调试
更新
.env中的MCP_TRANSPORT_TYPE，执行python main.py启动 mcp 服务器执行
npx @modelcontextprotocol/inspector打开检查。选择
SSE传输类型，URL 为http://localhost:<mcp_server_port>/sse或选择STDIO传输类型，命令为python，参数为/path/to/main.py
要求
Python >= 3.10
