+ You've likely used AI systems like ChatGPT or Claude, but have you ever wondered why they're limited to just conversation? Why can't they take meaningful actions in the real world? The fundamental limitation of traditional Large Language Models (LLMs) has been their inability to interact with the outside world - they can generate impressive text but can't directly impact their environment.

151
+ <h3 class="text-2xl font-semibold mb-4">Basic Concept: What is Function Calling?</h3>
152
+
153
+ <p class="mb-4 text-lg">
154
+ Function calling is the ability for an AI model to recognize when it needs to use an external tool or API, and to generate the proper structured arguments for that function call. It's essentially teaching AI when and how to use tools to accomplish tasks beyond simple text generation.
155

158
+ <h4 class="text-xl font-bold mb-3">Analogy: The New Intern</h4>
159
+ <p class="text-lg">
160
+ Imagine you've hired a new intern at your office. You've shown them all the available tools - Excel for spreadsheets, Email for communication, the printer for documents, etc. Now, whenever a task comes up, the intern decides which tool is appropriate. If they need to create a report, they use Excel. If they need to send a message, they use Email.
161
+ </p>
162
+ <p class="text-lg mt-3">
163
+ Similarly, with function calling, you tell the AI what functions are available (along with their descriptions and required parameters), and the AI decides when to use them and with what parameters based on the user's request.

340
+ The Model Context Protocol (MCP) is an open standard designed to connect AI systems with various data sources in a standardized way. Developed by Anthropic in November 2024, MCP creates a universal interface for AI systems to access content repositories, business tools, and development environments without custom integrations for each source.

527
+ The Agent-to-Agent (A2A) protocol is an open standard developed by Google in April 2025 that enables communication between different AI agents, regardless of which framework or vendor created them. A2A facilitates secure, standardized communication between independent AI systems, allowing them to collaborate on complex tasks.
