Can I use this to test my MCP server?

Yes, the skill includes a dedicated phase for creating evaluation questions and harnesses to verify tool reliability and accuracy before deployment.

Does this skill support both Python and Node.js?

Yes, it provides specific implementation guides, best practices, and SDK references for both Python (FastMCP) and Node/TypeScript environments.

How does this help with agent performance?

It provides design principles focused on building workflow-centric tools rather than simple API wrappers, which helps agents complete complex tasks with fewer errors.

What is an MCP server?

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

What is agent-centric design?

Agent-centric design is the practice of creating tools specifically for the constraints of AI agents, focusing on token efficiency, clear descriptions, and actionable error messages.
