Does this skill help with API research?

Yes, it includes a research phase that guides you through studying protocol documentation, SDKs, and target API specifications before writing code.

Why is agent-centric design important for MCP?

It ensures tools are optimized for how AI models process information, focusing on minimizing context window usage and providing actionable error messages.

What is an MCP server?

An MCP (Model Context Protocol) server is a standardized interface that allows LLMs like Claude to interact with external tools, APIs, and data sources securely.

How do I test my MCP server using this skill?

The skill includes a dedicated evaluation phase where you create XML-based QA pairs to verify that the LLM can successfully use your tools to solve complex tasks.

Which programming languages are supported by this skill?

This skill provides detailed implementation guides and best practices for both Python (using FastMCP) and Node/TypeScript environments.
