In simple English
This tool takes your API design files and turns them into ready-to-use software development kits and websites. It reads popular standard formats such as OpenAPI, GraphQL, and Protocol Buffers. It also creates MCP servers (Model Context Protocol, a way for artificial intelligence tools to talk directly to your data and code). You write your API rules once in a single configuration file. It costs you no money, but you need to know your way around the command line to run it.
What it is
Cortex is a command-line utility built in TypeScript that reads multiple API specification formats and combines them into unified documentation, client libraries, and AI-readable servers. It automates the tedious work of keeping documentation, software development kits, and AI context in sync when your API changes.
What it is good for
Solo builders who maintain an API and want to give both human developers and coding assistants an easy way to understand and use it without maintaining three separate toolchains.
- Combines OpenAPI, GraphQL, gRPC, AsyncAPI, and Markdown into one output.
- Generates typed software development kits for eleven different programming languages.
- Builds interactive documentation sites and Model Context Protocol servers at the same time.
- Requires Node.js installed on your machine and comfort with the command line.
- Some generated client libraries require the target language compiler or package manager to build.
- Mixing multiple different API specifications into one project can lead to naming conflicts.
