Turn API specs into docs, SDKs, and MCP servers

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.





The docs preview looks super clean. genuinely impressive work on unifying asyncapi and openapi into one workflow.

@uttam_kumar31 Haha, thanks! :) Yes, managing multiple separate docs was a major frustration when I was building API docs for clients, so I really wanted to create a tool that can support a single source of truth.
Second Brain for AI
sometimes I start with the docs but then get distracted rewriting API calls. if Cortex auto-generates integration code from specs, might save me from wandering off before everything's written up. but I always skip reading the full spec first, so who knows.
Love that Cortex treats AI agents and developers as first class consumers of the same spec, generating one source of truth into SDKs, docs, and MCP servers instead of duplicating the work.

@ilko_kacharov Thanks! Agree, it's much better when the spec serves both humans and AI agents without needing constant duplication.
