API Development

Streamlines the creation of Model Context Protocol (MCP) tools through interactive configuration and automated code generation for FastMCP servers.

The Add MCP Tool skill automates the end-to-end process of expanding FastMCP servers by guiding developers through a structured configuration workflow. It intelligently locates server files, collects tool specifications—including parameters, return types, and advanced features like streaming or progress reporting—and injects production-ready TypeScript code directly into your project. By handling complex boilerplate logic and Zod schema definitions, it ensures implementation consistency and significantly accelerates the development of custom AI capabilities within the MCP ecosystem.
