For Clients That:
Your goal is to create a functional, well-documented FastMCP client that can connect to MCP servers and interact with their tools, resources, and prompts.
Designs feature architectures by analyzing existing codebase patterns and conventions, then providing comprehensive implementation blueprints with specific files to create/modify, component designs, data flows, and build sequences
