In plain words
Cortex is an open-source API knowledge layer that converts API specifications like OpenAPI, AsyncAPI, GraphQL, gRPC, and OpenRPC into interactive documentation, typed SDKs across 11 languages, and MCP servers for AI agents. Developers use it to generate beautiful API docs for exploration, typed SDKs for application integration, and MCP tools that AI agents can access. The platform handles multiple protocol types through a single configuration workflow and is freely available under an MIT license.
