mcpgen is a command-line tool that generates boilerplate for an MCP server from OpenAPI 3 specifications. This tool allows you to easily expose existing APIs as powerful tools for AI agents. It reads OpenAPI specifications in YAML or JSON format and generates the complete Go boilerplate required for MCP server initialization, tool registration, and handler skeletons. Additionally, it automatically translates OpenAPI schemas into JSON schemas and generates response templates that provide rich context for AI models.
