Mcp Builder
Official/About Mcp Builder
This skill helps the assistant create MCP (Model Context Protocol) servers, which are small programs that let AI models connect to external services through well-designed tools. It walks through a four-phase process: researching the target API and protocol, implementing the server, reviewing and testing the code, and writing evaluation questions to check that AI models can actually use the finished server.
Use it when you ask the assistant to build an MCP server, integrate an external API as MCP tools, or improve an existing MCP project. It supports both Python (FastMCP) and TypeScript, and recommends TypeScript for new servers.
It also covers choosing between SDK versions, designing tool names and descriptions, handling errors and pagination, and picking the right transport (local stdio or remote streamable HTTP).
To do its work, the skill needs the assistant to read bundled reference guides (best practices, language-specific implementation guides, and an evaluation guide) and to fetch documentation from the web, including the MCP specification and SDK READMEs. Building and testing requires running commands like npm or python in a terminal, and testing uses the MCP Inspector tool.
No accounts or API keys are required by the skill itself, though the service you integrate may need its own credentials.
It works with assistants that can read SKILL.md files, such as Claude Code, and is aimed at people writing code rather than casual chat users.
