MCP Server Builder FAQs

Question 1

Which programming languages are supported by this skill?

Accepted Answer

This skill provides specific implementation guides and best practices for both Python (using FastMCP) and Node/TypeScript (using the MCP TypeScript SDK).

Question 2

How do I ensure my MCP server is high-quality?

Accepted Answer

Quality is achieved by following agent-centric design—creating tools for workflows rather than just wrapping endpoints—and using the evaluation-driven development process outlined in the skill.

Question 3

What is an MCP server?

Accepted Answer

An MCP (Model Context Protocol) server is a specialized bridge that allows LLMs like Claude to interact with external APIs, services, and databases through a standardized set of tools.

Question 4

How do I test my MCP server safely?

Accepted Answer

The skill recommends using an evaluation harness or running the server in a separate environment like tmux, as running it directly in your main process can cause it to hang while waiting for stdio requests.

Question 5

What is agent-centric design?

Accepted Answer

It is a design philosophy that optimizes tools for AI agents by returning high-signal information, minimizing token usage, and providing actionable error messages that guide the agent toward success.
