How does this skill improve AI agent performance?

It emphasizes agent-centric design, teaching you how to create tools that are optimized for context limits, provide actionable feedback, and group operations into logical workflows.

What is the Model Context Protocol (MCP)?

MCP is an open standard that enables AI models to interact with external data sources and tools through a unified interface, allowing agents to perform real-world tasks.

Does it support automated testing?

Yes, it includes instructions for code quality reviews, safe testing methods for long-running processes, and an evaluation harness for verification.

What is the purpose of the Evaluation phase?

Evaluations test whether LLMs can effectively use your MCP server to answer realistic, complex questions by simulating multi-step tool usage.

Can I build servers in both Python and JavaScript?

Yes, this skill provides specialized implementation guides for both the Python (FastMCP) and Node/TypeScript SDKs.
