Description
Cortex is an open source API knowledge layer that turns OpenAPI, AsyncAPI, GraphQL, gRPC, and OpenRPC specs into interactive documentation, typed SDKs in 11 languages, and MCP servers for AI agents.

Could you build this?
Partial A single parser or doc UI is straightforward, but building a production-grade multi-protocol compiler across OpenAPI, AsyncAPI, GraphQL, gRPC, and OpenRPC that outputs idiomatic SDKs in 11 languages requires extensive compiler/codegen expertise.
What it would actually take: The system requires an AST-based intermediate representation layer that normalizes schemas from GraphQL, protobuf/gRPC, and OpenAPI/AsyncAPI specifications. From this AST, it must run sophisticated template engines (e.g., EJS/Handlebars or custom code generators) tailored to 11 programming languages' idioms, package managers, type systems, and async runtimes. Maintaining high-fidelity typing and error-free code generation across varying language paradigms demands deep multi-language systems expertise.
