Does this skill support both Python and TypeScript?

Yes, it provides detailed implementation guides for both the Python SDK (including FastMCP) and the Node/TypeScript MCP SDK.

What is an MCP server?

An MCP (Model Context Protocol) server is a specialized interface that allows Large Language Models (LLMs) to interact securely with external tools, APIs, and data sources using a standardized protocol.

How does 'Agent-Centric Design' improve my tools?

It focuses on building tools around human-like workflows rather than just mirroring API endpoints, ensuring the AI can complete tasks more efficiently while staying within context window limits.

Can I use this to test my MCP tools?

Absolutely. The skill includes a dedicated phase for evaluation-driven development, helping you create 10+ realistic QA pairs to verify that your server handles complex, real-world requests correctly.
