Cortex Docs

Cortex Docs is an API platform that converts API specifications and Markdown into interactive documentation, typed SDKs, and MCP servers for AI agents.

Cortex Docs turns API specifications and Markdown files into comprehensive developer and agent interfaces. It accepts REST, GraphQL, gRPC, JSON-RPC, and AsyncAPI sources to generate interactive documentation sites, typed SDKs, and Model Context Protocol (MCP) servers. The platform maps API operations to typed tools for AI agents, providing them with grounded context, SDK references, and source specs to minimize prompting. Generated SDKs support 11 languages with idiomatic conventions including authentication, retries, and native package management. It is an MIT-licensed, open-source toolchain that allows teams to override templates and self-host the resulting output.
