# Geek Time Column Learning Journey [👉 Click to enter the column introduction page](https://time.geekbang.org/column/intro/101053801) --- Since its launch two weeks ago, this column has had nearly 3,000 students join the learning journey. Welcome to start the door to knowledge exploration together!  ---  --- ## What is the MCP Protocol? MCP (Multi-Channel Protocol) is a general communication protocol for AI Agents, designed to achieve efficient collaboration and resource sharing between multiple agents. The MCP protocol supports multiple data types, tool calls, resource discovery, and other capabilities, and is the basic communication bridge of modern intelligent agent systems.  The core features of the MCP protocol include: - Support for multiple communication channels (such as standard input and output, network, etc.) - Unified message format for easy expansion - Rich tool call and resource discovery mechanisms --- ## Column Introduction This column takes the MCP protocol as the core and takes you from scratch to practice the key capabilities of AI Agent's communication, tool calling, resource discovery, and prompt templates. The content covers: - MCP protocol principle and implementation - Typical AI Agent communication scenarios - Toolchain and resource management - Prompt templates and agent collaboration Through theory combined with a large number of practical codes, it will help you quickly master the core skills of AI Agent development.  --- Welcome to follow the column and start your AI Agent development journey!
