Introduction

This video provides a step-by-step tutorial on building a local MCP (Model Context Protocol) server. It explains what MCP is, why it's popular, its use cases, and demonstrates its functionality with a local server interacting with a cloud desktop. The tutorial includes a code walkthrough using the Python SDK and showcases the MCP Inspector.

Key Takeaways

• MCP (Model Context Protocol): An open standard application protocol enabling communication between large language models (LLMs) and various data sources and tools. It acts as a standardized connector, similar to USB.
• MCP Architecture: Follows a client-server architecture. A host application (client) connects to multiple MCP servers, which can access local data sources (computer files, databases) and remote services (internet APIs).
• Python SDK: The video uses the Python SDK to build a local MCP server, but other SDKs exist (TypeScript, Java, Kotlin, and SH).
• MCP Inspector: A tool for debugging and interacting with the MCP server, allowing users to list tools and execute commands.
• Pulse MCP: A website (pulsemcp.com) that lists open-source MCP servers and clients, showcasing various projects and use cases.
