MCP Builder

概要

MCP Builder serves as a comprehensive framework for developers looking to create robust Model Context Protocol (MCP) servers that bridge the gap between LLMs and external services. It guides users through a professional four-phase workflow—spanning deep research, implementation using TypeScript or Python SDKs, rigorous testing with the MCP Inspector, and the creation of verifiable evaluations. By focusing on tool discoverability, clear schemas, and actionable error handling, this skill ensures that developers can build performant integrations that allow AI agents to navigate complex real-world workflows with precision.
