How do I test the MCP servers I build?

The skill includes a dedicated evaluation phase where you create complex, multi-step test cases to verify that an LLM can successfully navigate your tools to solve real-world tasks.

What is an MCP server?

An MCP (Model Context Protocol) server is a specialized service that provides tools and resources, allowing LLMs like Claude to interact with external APIs, databases, and local files through a standardized protocol.

Does this skill support both Python and TypeScript?

Yes, it provides dedicated implementation guides for both Python (using FastMCP) and Node/TypeScript (using the official MCP SDK), including environment setup and best practices for each.

What is agent-centric design?

Agent-centric design is a methodology that focuses on building tools specifically for LLM consumption, prioritizing concise, high-signal data and actionable error messages over raw API output.
