MCP Starter is a GitHub template designed for building MCP servers, ensuring A+ schema quality from the outset. It features clearly defined tool descriptions with types and efficient parameter management, minimizing token waste. The template includes a CI grading system that automatically evaluates schema quality on every commit using GitHub Actions, along with a pre-commit hook to catch potential schema issues before they reach the CI stage. Additionally, it provides example tools that demonstrate best practices in MCP schema design.

The program is structured to facilitate a smooth setup process, allowing users to create a new repository from the template and customize it according to their server's needs. The included schema quality checklist guides users in ensuring every tool is well-defined and optimized for performance. By starting with a solid schema, users can avoid costly retrofitting later, making MCP Starter an essential tool for developers looking to build efficient MCP servers.
