What is the Model Context Protocol (MCP)?

MCP is an open protocol that allows LLMs to interact with external data sources and tools through a standardized interface.

Why should I use this instead of just writing a basic API wrapper?

This skill emphasizes agent-centric design, helping you create tools that are optimized for context limits, have better error handling, and support complex workflows rather than just mirroring endpoints.

Does this skill support both Python and Node.js?

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

How does this skill help with testing?

It includes a dedicated phase for creating evaluation scenarios (QA pairs) to verify that your MCP server works reliably in real-world situations and produces stable answers.
