1. Continuing from the previous content, the video content, look at this architecture diagram

2. Let’s look at the differences between MCP, Agent, and Function call

MCP tells the AI ​​Agent the capability list of different services and platforms. The AI ​​Agent determines whether a service needs to be called based on the context and model reasoning, and then uses Function Calling to execute the function. This function is told to Function Calling through MCP, and finally the whole process is completed through the specific code provided by the MCP protocol.
