Can I use this for Node.js or TypeScript?

Absolutely. It provides full implementation patterns for Node.js and TypeScript development using the official MCP TypeScript SDK and Zod schemas.

What are agent-centric design principles?

They are strategies to optimize tools specifically for LLMs, focusing on concise data output, actionable error messages, and task-oriented workflows rather than simple API wrapping.

Does this skill support Python development?

Yes, it includes specialized guidance for Python using the FastMCP framework and Pydantic for robust data validation.

What is an MCP server?

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

How does it help with testing my MCP tools?

The skill includes a dedicated evaluation phase for creating test questions and XML-based QA pairs to ensure your MCP tools work reliably in real-world scenarios.
