What is the Model Context Protocol (MCP)?

MCP is an open standard that enables LLMs to securely interact with local or remote data sources and tools through a unified interface, allowing for seamless API integrations.

How do I test my MCP server using this skill?

The skill guides you through using the MCP Inspector to verify tool functionality, debug transport issues, and ensure your server communicates correctly with the protocol.

Does this skill support Python development?

Yes, MCP Builder provides specific implementation guides and best practices for both Python (using FastMCP) and TypeScript (using the official MCP SDK).

Why should I create evaluations for my MCP server?

Evaluations (QA pairs) are critical for ensuring that the LLM can successfully navigate complex tasks using your tools and consistently produce correct results in real-world scenarios.
