AI Makerspace MCP Server

AI Makerspace: MCP Session Repo for Session 13

This project is a demonstration of the MCP (Model Context Protocol) server, which utilizes the Tavily API for web search capabilities. The server is designed to run in a standard input/output (stdio) transport mode.

Project Overview

The MCP server is set up to handle web search queries using the Tavily API. It is built with the following key components:

• TavilyClient: A client for interacting with the Tavily API to perform web searches.

Prerequisites

• Python 3.13 or higher

• A valid Tavily API key

⚠️NOTE FOR WINDOWS:⚠️

You'll need to install this on the Windows side of your OS.

This will require getting two CLI tool for Powershell, which you can do as follows:

• winget install astral-sh.uv

• winget install --id Git.Git -e --source winget

After you have those CLI tools, please open Cursor into Windows.

Then, you can clone the repository using the following command in your Cursor terminal:

After that, you can follow from Step 2. below!

Installation

1. Clone the repository:

   git clone <repository-url> cd <repository-directory>

2. Configure environment variables: Create a .env file in the project root and add your API keys:

   TAVILY_API_KEY=your_api_key_here COINGECKO_API_KEY=your_coingecko_api_key_here # Optional - free tier works without key but has rate limits

   Note: CoinGecko API can work without an API key, but using one provides higher rate limits (10-50 calls/minute with free tier).

3. 🏗️ Add a new tool to your MCP Server 🏗️

Create a new tool in the server.py file, that's it!

Running the MCP Server

To start the MCP server, you will need to add the following to your MCP Profile in Cursor:

NOTE: To get to your MCP config. you can use the Command Pallete (CMD/CTRL+SHIFT+P) and select "View: Open MCP Settings" and replace the contents with the JSON blob below.

The server will start and listen for commands via standard input/output.

Usage

The server provides several tools:

• web_search: Search the web for information about a given query using Tavily API

• roll_dice: Roll dice with standard notation (e.g., "2d20k1" for 2 twenty-sided dice, keep highest 1)

• get_crypto_price: Get current cryptocurrency price and market data from CoinGecko API (e.g., "bitcoin", "ethereum")

Activities:

There are a few activities for this assignment!

🏗️ Activity #1:

Choose an API that you enjoy using - and build an MCP server for it!

🏗️ Activity #2:

Build a simple LangGraph application that interacts with your MCP Server.
