FastMCP Dependency Injection Patterns - Part 17/17

Learn how FastMCP 2.0 implements hierarchical dependency injection using the Depends() construct to create modular, maintainable code structures. This tutorial demonstrates nested dependency resolution in a bottom-up fashion, showcasing how dependencies form a directed acyclic graph for clean separation of concerns. #FastMCP #DependencyInjection #Python #SoftwareDesign #MCP #BackendDevelopment #CleanCode Zen Koan Explanation: The code demonstrates **dependency injection chaining**, where `Depends(get_api_client)` triggers `get_api_client`, which in turn calls `Depends(get_base_url)`, creating a recursive resolution path. This mirrors the koan's theme of circular pursuit—each dependency "chases" the next until the system resolves the chain, much like a server momentarily losing track of the original function call in the process.
