PS:This file only provides the method which sets up the Virtual Environment by UV.Thus if you want to use the following examples,you ought to download that.

PS:You can open the file "UV And It's Functions.txt" or visit "https://docs.astral.sh/uv/" to learn more about UV.If you've already download UV,just type UV in the Power Shell.

PS:We use the VS Code and Cline to solve the tasks

I.MCP And MCP Server

MCP:Model Context Protocol

MCP (Model Context Protocol) is an open protocol that enables AI models to securely interact with local and remote resources through standardized server implementations. It follows a client-host-server architecture, allowing integration of AI functionality in applications while maintaining clear security boundaries and isolation focus.

MCP Sever:

A file or any other things that provides MCP serves.

II.Steps To Build Up A MCP Server

1st. Set Up Virtual Environment

Use the following codes to set up a new Virtual Environment:

uv venv <NAME>(If the <NAME> remains unfilled ,it uses <.venv>)

2nd.Alter And Check The Environment

Press "Ctrl" +"Shift"+"P",choose "Python:Select Interpreter" and then click your Virtual Environment(<.venv> etc.)If the environment variable has been changed,please reboot the VS Code to make sure the environment is available.The VS Code has already activated the environment so you needn't stir it up by yourself

3rd.Install The Required Resources

Use the following codes install the resources:

uv pip install <RESOURCE NAME>

4th.Write your MCP Server File(Python Files)

our file must include the following codes:

from fastmcp import FastMCP

# Initialize FastMCP server

mcp = FastMCP("<SERVER'S NAME>")

#Constants

@mcp.tool()

async def <TOOL NAME>(<PARAMETERS NAME1>:<INPUT TYPE>,<PARAMETERS NAME2>:<INPUT TYPE>,......)-><OUTPUT TYPE>:

"""<FUNCTION AND DESCRIPTION OF THE TOOL>
