How do I test my MCP server?

The guide recommends using the MCP Inspector for interactive testing and provides a framework for creating XML-based evaluation datasets to verify tool effectiveness.

Does this skill support Python and TypeScript?

Yes, it includes detailed implementation guides and patterns for both the TypeScript MCP SDK and Python's FastMCP framework.

What is an MCP server?

An MCP (Model Context Protocol) server is a specialized service that allows Large Language Models (LLMs) to interact with external tools, APIs, and data sources through a standardized protocol.

What is the difference between comprehensive API coverage and workflow tools?

Comprehensive coverage maps individual API endpoints, providing maximum flexibility, while workflow tools combine multiple actions into high-level tools for specific common tasks.

Why is tool naming important in MCP?

Clear, action-oriented naming (e.g., github_create_issue) ensures that AI agents can easily discover and select the correct tool for a specific task.
