MCP-YNU - FastMCP Server

A dynamic MCP server implementation using FastMCP that automatically loads tools, resources, and prompts from respective directories.

Features

• Dynamic loading of modules from tools/, resources/, and prompts/ directories
• Automatic discovery and registration of modules
• Simple configuration and extensibility
• Type hints for better code clarity and static analysis
• Comprehensive logging for monitoring server activity

Recent Updates

• Added type hints throughout the codebase
• Improved MCP instance handling
• Added logging functionality
• Added MIT license
• Updated documentation with reference links

Usage

1. Create modules in the appropriate directories
2. Import mcp via from mcp_server import mcp
3. Run the server:

python main.py

Example Modules

Tools Module Example (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

Resources Module Example (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}"

Prompts Module Example (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?"),
    ]

Debugging

1. Update MCP_TRANSPORT_TYPE in .env, Execute python main.py to start the mcp server
2. Execute npx @modelcontextprotocol/inspector to open the inspect.
3. Choose SSE Transport Type with URL http://localhost:<mcp_server_port>/sse or Choose STDIO Transport Type with Command python and Arguments /path/to/main.py
