What it is

OpenAgentCore runs AI agents on your own infrastructure behind the OpenAI Agents API.

Same API as OpenAI. Point the official OpenAI SDK, or plain HTTP, at your installation. No new client to learn.
Your choice of agent. Each Session runs a native harness: Codex, Claude Code or MiniMax Code, with the model provider you configure.
Your choice of machine. Agents work in a managed sandbox (Docker, microsandbox or E2B), or on your own Linux, macOS or Windows machine.
Every part is replaceable. Sandboxes, harnesses and model providers plug in through defined protocols.

Install

On a Linux amd64 host with Docker and Python 3.9+:

curl -fsSL https://github.com/MiniMax-AI/OpenAgentCore/releases/latest/download/install.sh | bash

Then:

Sign in to Web, the admin console, with the Core key the installer created, and configure the domain and HTTPS.
Set a default model and issue a Project API key.
Add execution capacity: a node, E2B, or your own machine.
Run your first Session with the OpenAI SDK.

The [installation guide](docs/getting-started/install.md) covers each step, HTTPS and a quick local trial. Listen addresses, ports and other options: [installation options](docs/getting-started/install-options.md).
