What Is Cortex? Product Overview

What the product does and how it is positioned

Cortex serves as an API interface generator designed to bridge human developers and automated agents. Governed by a single configuration file, the system ingests multiple contract formats including OpenAPI, AsyncAPI, GraphQL, gRPC, and OpenRPC, verifying schema validity before generating project assets.

Through a unified command-line workflow, Cortex outputs an interactive documentation site with live testing capabilities, native SDKs across eleven distinct programming languages, and an MCP server that packages API endpoints as typed tools for agentic integration.

What Can You Use Cortex For?

Source-supported ways to use the product

Multi-Protocol API Documentation

Engineering teams managing REST, realtime, GraphQL, or RPC interfaces can generate a unified, self-hosted documentation site with searchable references and interactive request tools.

AI Agent Integration via MCP

Developers can generate Model Context Protocol servers to provide AI agents with typed tool schemas, embedded specifications, and client instructions directly from their API contracts.

Cross-Language Client Generation

API providers can compile client libraries in eleven programming languages featuring built-in retries, authentication, and streaming.

How to Use Cortex

The documented workflow, where available

  1. 1

    Define Project Configuration

    Specify input sources such as OpenAPI, AsyncAPI, GraphQL, gRPC, or OpenRPC files alongside MCP package settings in a configuration file.

  2. 2

    Execute Generation

    Run the generation command to validate source contracts and compile interactive documentation, client SDKs, and the MCP server.

  3. 3

    Deploy Outputs

    Deploy the interactive documentation site to a Node-compatible host, publish client libraries to language package registries, and connect the MCP server to AI agents.

MCP Tool Generation for Agentic Workflows

Cortex translates API contracts into typed Model Context Protocol servers tailored for autonomous development agents. Each operation defined in the source specifications maps directly to a typed tool schema, eliminating ambiguity during automated tool selection.

Alongside tool definitions, the server bundles source specifications, documentation guides, and client library references. This structure gives connected agents grounded context to identify relevant endpoints, install appropriate SDK packages, and generate typed integration code.

  • Maps API operations directly into typed MCP tool schemas
  • Packages source specifications and documentation alongside agent tools
  • Enables automated discovery of SDK packages and typed request structures

Unified Multi-Protocol Code and Documentation Generation

Cortex unifies multiple API architectural styles into a single pipeline. Teams can combine REST, WebSocket, GraphQL, gRPC, and JSON-RPC definitions within one configuration, which Cortex validates prior to asset compilation.

The engine generates idiomatic client libraries in eleven languages, including TypeScript, Python, Go, Java, and Rust, incorporating standard network handling such as timeouts, retries, authentication, and streaming. Developers can also export and override Eta templates to alter generated outputs.

  • Validates contracts across five API protocol standards before generation
  • Produces idiomatic client SDKs in eleven programming languages
  • Allows full code customization through overrideable Eta templates

What to Test Before Choosing Cortex

Checks to run with your own material and workflow

  • Verify that your API specifications use supported formats such as OpenAPI, AsyncAPI, GraphQL, gRPC, or OpenRPC.
  • Confirm that your hosting infrastructure can run Node to host the generated interactive documentation site.
  • Review the generated client code across your required programming languages to ensure naming conventions and network handling align with internal standards.
  • Check that your AI agent environments support the Model Context Protocol to utilize the generated MCP server.
