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

  • tools/resources/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

  1. 在适当的目录中创建模块

  2. 通过from mcp_server import mcp

  3. 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

  1. 更新.env中的MCP_TRANSPORT_TYPE ,执行python main.py启动 mcp 服务器

  2. 执行npx @modelcontextprotocol/inspector打开检查

  3. 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

@modelcontextprotocol/检查器

要求

  • Python >= 3.10

  • FastMCP
