How It Works

Getting Started

Installing uv Package Manager

On MacOS/Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Make sure to restart your terminal afterwards to ensure that the uv command gets picked up.

Project Setup

Create and initialize the project:

# Create a new directory for our project uv init mcp-server cd mcp-server # Create virtual environment and activate it uv venv source .venv/bin/activate # On Windows use: .venv\Scripts\activate # Install dependencies uv add "mcp[cli]" httpx python-dotenv bs4

Environment Variables

Create a .env file in the root directory and add the following:

SERPER_API_KEY=YOUR_SERPER_API_KEY

You'll need a SERPER API key to use the web search functionality. You can obtain one from Serper.dev. We are using the Serper API to search the web for relevant documentation.
