Which programming languages does this skill support?

The mcp-builder skill supports both Python (using the FastMCP framework) and Node.js/TypeScript (using the official MCP SDK).

What is agent-centric design in the context of MCP?

It is a design philosophy that focuses on building tools around natural human workflows and AI context limitations rather than just mirroring technical API endpoints.

What is an MCP server?

An MCP (Model Context Protocol) server is a specialized service that provides tools and resources allowing LLMs to interact safely and effectively with external APIs, databases, and services.

How does this skill improve tool reliability?

It provides a structured evaluation phase where you create complex, verifiable QA pairs to ensure the LLM can successfully use the tools to solve multi-step, real-world problems.

How do I safely test an MCP server?

The skill recommends using an evaluation harness or running the server in a separate process (like tmux) to prevent the long-running stdio process from hanging your main development environment.
