A simple demo of MCP python sdk.

MCP Crash Course

uv commands

start a new project

uv init <project-name>

create a virtual environment

uv venv

activate the virtual environment

uv venv --activate

install the dependencies

uv add <package>
uv add -r requirements.txt
uv sync

run application

uv run app.py

run the development server

uv run dev

build the project

uv run build

Run server using MCP Inspector :

• Install MCP python sdk

uv add "mcp[cli]"

• Run mcp inspector

uv run mcp dev server/weather.py

MCP Inspector is up and running at http://127.0.0.1:6274

Add server to claude desktop :

• run command

uv run mcp install .serverweather.py

• query “what is weather alert in CA” in claude desktop

Add server to cursor :

• goto preferences > settings > mcp and copy paste claude config

{
  "mcpServers": {
    "weather": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "C:\Users\Suraj\Desktop\Python\mcp-crash-course\mcpcrashcourse\server\weather.py"
      ]
    }
  }
}

• Then do a query in cursor chat

Directly consume server in code - using mcp-use :

• Install mcp-use

uv add mcp-use

• Install langchain-groq

uv add langchain-groq

• run client

uv run server/client.py
