Configuration

For basic configuration instructions, see this documentation.

For advanced configuration instructions, see this documentation.

For a full configuration reference, see this documentation.

Connecting to MCP servers

Codex can connect to MCP servers configured in ~/.codex/config.toml. See the configuration reference for the latest MCP server options:

Apps (Connectors)

Use $ in the composer to insert a ChatGPT connector; the popover lists accessible apps. The /apps command lists available and installed apps. Connected apps appear first and are labeled as connected; others are marked as can be installed.

Notify

Codex can run a notification hook when the agent finishes a turn. See the configuration reference for the latest notification settings:

JSON Schema

The generated JSON Schema for config.toml lives at codex-rs/core/config.schema.json.

Notices

Codex stores "do not show again" flags for some UI prompts under the [notice] table.

Ctrl+C/Ctrl+D quitting uses a ~1 second double-press hint (ctrl + c again to quit).
