I have created a new mcp tool in the main.py file along with the add tool. The add tool is showing in the claude desktop but the newly added one is not visible, can someone please tell me how to see list of all mcp.tools in claude desktop?

cd to the examples/snippets/clients directory and run:

from mcp.server.fastmcp import FastMCP

Create an MCP server

mcp = FastMCP("Demo")

Add an addition tool

@mcp.tool()
def add(a: int, b: int) -> int:
"""Add two numbers"""
return a + b

Add a weather tool

@mcp.tool()
def get_weather(city: str) -> str:
"""Get current weather information for a city using OpenWeatherMap API"""
api_key = "9c6670473f13b951f8df8f5aeb30cfdc"

if not api_key:
    return "Error: OpenWeatherMap API key not found. Please set OPENWEATHER_API_KEY environment variable."

try:
    # OpenWeatherMap API endpoint
    url = f"http://api.openweathermap.org/data/2.5/weather?q={city}&appid={api_key}&units=metric"
    
    response = requests.get(url)
    response.raise_for_status()
    
    data = response.json()
    
    # Extract relevant weather information
    weather_desc = data['weather'][0]['description'].title()
    temp = data['main']['temp']
    feels_like = data['main']['feels_like']
    humidity = data['main']['humidity']
    city_name = data['name']
    country = data['sys']['country']

           f"Temperature: {temp}°C (feels like {feels_like}°C)\n" \
           f"Humidity: {humidity}%"

except requests.exceptions.RequestException as e:
    return f"Error fetching weather data: {str(e)}"
except KeyError as e:
    return f"Error parsing weather data: {str(e)}. Please check if the city name is correct."

Add a dynamic greeting resource

@mcp.resource("greeting://{name}")
def get_greeting(name: str) -> str:
"""Get a personalized greeting"""
return f"Hello, {name}!"

Add a prompt

@mcp.prompt()
def greet_user(name: str, style: str = "friendly") -> str:
"""Generate a greeting prompt"""
styles = {
"friendly": "Please write a warm, friendly greeting",
"formal": "Please write a formal, professional greeting",
"casual": "Please write a casual, relaxed greeting",
}

return f"{styles.get(style, styles['friendly'])} for someone named {name}."`
