MCP Server Creation and MCP client connection (Agent-Claude,cursor or, custom server calling and integration with local LLMs).
This project demonstrates how to create and connect an MCP (Model Context Protocol) weather server using FastMCP.

Prerequisites
- Python 3.13+
uvpackage manager installed
Setup Instructions
1. Initialize the Project
Initialize a new project using uv:
uv init
2. Create Virtual Environment
Create a virtual environment for the project:
uv venv
3. Activate Virtual Environment
Activate the virtual environment:
Windows:
.venv\Scripts\activate
Linux/Mac:
source .venv/bin/activate
4. Install MCP CLI
Add the MCP CLI package to enable fast MCP CLI commands:
uv add "mcp[cli]"
Running the MCP Server
Development Mode
To run the MCP server in development mode:
uv run mcp dev server/weather.py
Expected Output:
Starting MCP inspector...
⚙️ Proxy server listening on localhost:6277
Connecting to Claude Desktop
Install Server to Claude
Add the weather server to Claude Desktop:
uv run mcp install server/weather.py
Expected Output:
Added server 'weather' to Claude config
Successfully installed weather in Claude app
Once installed, you can ask Claude questions like:
- "What are the weather alerts in CA?"
- The MCP server will be called automatically and display the results.
Manual Configuration for Cursor or Other Clients
For Cursor or other clients, you'll need to manually configure the server using the Claude Desktop config file format.
Get the server configuration from: claude_desktop_config file
Example Configuration:
"weather": {
"command": "C:\\Users\\gaura\\AppData\\Local\\Programs\\Python\\Python313\\Scripts\\uv.EXE",
"args": [
"run",
"--with",
"mcp[cli]",
"mcp",
"run",
"C:\\Users\\gaura\\OneDrive\\Desktop\\AI projects\\mcp_project\\server\\weather.py"
]
}
Note: Update the paths in the configuration to match your system paths.
Usage in Cursor:
- Go to MCP → mcp config.json
- Add the configuration above
Using MCP with Local LLMs (mcp-use)
mcp-use allows you to connect to MCP servers directly without an AI agent for programmatic tool access. This is useful for custom server calling and integration with local LLMs.
Installation
Install the mcp-use package:
uv add mcp-use
Configuration
Create a file named weather.json and add the following configuration to connect local LLMs to the MCP server:
{
"mcpServers": {
"weather": {
"command": "C:\\Users\\gaura\\AppData\\Local\\Programs\\Python\\Python313\\Scripts\\uv.EXE",
"args": [
"run",
"--with",
"mcp[cli]",
"mcp",
"run",
"C:\\Users\\gaura\\OneDrive\\Desktop\\AI projects\\mcp_project\\server\\weather.py"
]
}
}
}
Note: Update the paths in the configuration to match your system paths.
