Understand what MCP is and how it extends agent capabilities through external servers.

The problem: Capabilities beyond what's build in

The solution: Model Context Protocol (MCP)

MCP tools

This part teaches you to create custom function tools tailored to your specific business logic and requirements. You'll learn to write effective tool functions with proper signatures, docstrings, and return values that the LLM can understand and use effectively.

The problem: Generic tools versus specific business needs

The solution: Custom function tools

Custom function tools

This part teaches you to design strategic instructions that guide agents to use multiple tools effectively. You'll learn instruction patterns, error handling strategies, and when to use specialized agents as tools.

The problem: Tools without guidance

The solution: Strategic instruction design

Combining tools effectively
