Mcpgen is a code generator for MCP servers in Go (github.com)

Mcpgen is a newly launched code generator designed for Model Context Protocol (MCP) servers using Go, inspired by the popular gqlgen. It employs a schema-first approach that allows developers to define tools, resources, and prompts within a YAML configuration file, accompanied by JSON Schema definitions. This innovation aims to streamline the development of type-safe Go code, generating everything from type-safe structs to boilerplate server code, along with handler stubs that can be filled with business logic. The integration of the official go-sdk enhances its utility, ensuring a seamless build process. The significance of Mcpgen for the AI/ML community lies in its focus on creating structured, type-safe interactions for language models with external systems. By leveraging JSON Schemas, developers can define precise input and output requirements for their MCP tools, leading to more reliable and maintainable applications. Key features include the preservation of user-defined handler implementations during code regeneration and the ability to use custom Go types, ensuring that existing codebases can be integrated without significant modification. This tool not only simplifies server setup but also nurtures a robust foundation for building applications that incorporate advanced AI capabilities.
