Build a Model Context Protocol (MCP) server to enable smart Gmail actions in a LangGraph agent. This intermediate level project guides you through creating a smart email management system using OpenAI's GPT models and Anthropic's MCP. You’ll implement Gmail OAuth, design a React user interface with an Express backend, and build an agent that can manage emails with natural language prompts. By the end of the project, you'll be proficient with the MCP SDK and understand it's many practical use cases. Enroll now to learn this cutting-edge technology used across countless industries.

AI agents are transforming how we interact with technology, automating tasks that once took hours into just a few clicks. By learning to build a Model Context Protocol (MCP) server and a LangGraph agent, you’ll gain hands-on experience in connecting AI models to real-world tools. This project is especially exciting because it shows how AI can manage everyday tasks, like email, using natural language—making technology smarter and more accessible. Completing this project will give you practical skills that can be applied to productivity tools, automation workflows, and modern AI applications.
