What is an MCP server?

An MCP (Model Context Protocol) server is a specialized application that allows Large Language Models to interact with external data and services through a standardized interface.

How does this skill help with tool naming?

The skill provides guidance on using action-oriented naming and consistent prefixes to ensure AI agents can easily discover and select the correct tool for a given task.

What is the recommended way to test an MCP server?

The guide recommends using the MCP Inspector for local testing and creating a structured evaluation suite with 10 complex questions to verify LLM performance.

Should I use TypeScript or Python for my MCP server?

Both are supported. TypeScript is recommended for its high-quality SDK and compatibility with many execution environments, while Python (FastMCP) is excellent for rapid development and data-heavy applications.

What transport mechanisms does the mcp-builder suggest?

It recommends Streamable HTTP for remote servers due to its scalability, and stdio for local servers used within a desktop environment.
