What is an MCP server?

An MCP (Model Context Protocol) server is an open standard that enables LLMs to safely interact with external data sources and services through clearly defined tools, resources, and prompts.

Does this skill support both Python and TypeScript?

Yes, mcp-builder provides specific implementation guides, project structures, and best practices for both the Python (FastMCP) and Node/TypeScript SDKs.

How does mcp-builder improve tool discoverability?

It provides strict naming conventions and description patterns that help AI agents quickly identify and correctly utilize the right tools for a given task.

Can I use this for local and remote server development?

Absolutely. The skill covers transport mechanisms for both local development (stdio) and scalable remote deployments (streamable HTTP).

What is the benefit of the Evaluation Phase in this skill?

The evaluation phase helps you create 10 complex, realistic QA pairs to verify that the LLM can effectively use your tools to solve multi-step problems accurately.
