OpenAI Codex

Overview

Use the remote oleander MCP server in OpenAI Codex to connect your agent workflows directly to oleander.

Beta: MCP integration docs and workflow may change.

Add the oleander server to your Codex config at ~/.codex/config.json:

{
  "mcpServers": {
    "oleander": {
      "type": "streamableHttp",
      "url": "https://oleander.dev/mcp"
    }
  }
}

If you already have other MCP servers configured, add only the oleander entry under mcpServers.

Ask Codex to confirm it’s connected:

“Are you connected to oleander? Who am I authenticated as?”

Codex will call the “who am i” tool and return your organization context.
