Cortex turns API specifications and Markdown into typed SDKs, interactive documentation, and an MCP server from one project configuration.

Cortex combines OpenAPI, AsyncAPI, GraphQL, Protocol Buffer, OpenRPC, and Markdown sources. Developers get interactive documentation, applications get typed SDKs, and AI agents get an MCP server with project context.
If Cortex helps your team, star this repository to support its development.
Try Cortex in 60 seconds
Start a local demo:
mkdir petstore
cd petstore
npm install --global @cortex-docs/cli
cortex init petstore
cortex docs serve
Open http://localhost:3012. Press Ctrl+C to stop the server.
We love open source
Keep your Markdown in Git. Add cortex.config.yml to the default branch of your public GitHub repository, then run:
npx -y @cortex-docs/cli deploy https://github.com/OWNER/REPO
npx -y @cortex-docs/cli mcp-serve https://github.com/OWNER/REPO
The first command publishes a free documentation site at PROJECT.cortexdocs.dev. The second connects AI clients to current documentation through local MCP.
Deploy requires repository write access. MCP works with public read access and checks for changes before each request.
See the open source hosting guide for configuration, custom domains, automatic updates, and limits.
