# SDK Generator

> Six surfaces from one OpenAPI description. The generator reads your OpenAPI description, extracts a type-safe semantic model, and generates an SDK, a CLI, an MCP Server, Agent Skills, a REPL and the Semantic Model from it. This section is the repositories behind it.

## What it is

The generator is the project most people meet first. npm create @voxgig/sdkgen reads an OpenAPI description, extracts a type-safe semantic model of the API, its entities, their attributes and the operations on them, and generates six surfaces from that one model. Change the description and all six regenerate together. The product page explains what it does for you; this page is about the code.

It is a toolchain, not one repository. create-sdkgen scaffolds a project. apidef reads OpenAPI 3 or Swagger 2 and produces the API model, and apidef-validate is the corpus of real API definitions that a release of apidef is checked against. sdkgen itself turns the model into code. docgen generates a documentation site from the same model. station is a control surface for the outbound integrations an application makes through its generated SDKs, and station-view is its local viewer.

Everything in it is MIT licensed, and the code it generates belongs to whoever ran it. Read the repositories below, or start from the product page and the agent guide.
