Codex supports remote MCP servers over Streamable HTTP, configured as TOML in ~/.codex/config.toml — either by editing the file directly or using the codex mcp add CLI command.
1

Get a Poix Token

If you don’t already have one, create a poix- Token in the Dashboard. See Authentication for details.
2

Add the Poix server

Use the Codex CLI:
Or add it directly to ~/.codex/config.toml:
config.toml
3

Set your token

Export your Poix Token as the environment variable Codex reads:
Replace poix-… with your actual Token, then restart Codex.
4

Verify the connection

Ask Codex to list its available tools — poix’s tools (search, video/channel details, captions, and more) should appear. You can now ask it to look up YouTube data directly.
Codex’s TOML config also supports env_http_headers, which can pass a full Authorization header directly instead of using bearer_token_env_var.
