Slim down codex cli with this command:

codex features disable apps

Which is equivalent to adding this to config.toml:

[features]
apps = false

I’m trying codex. First thing I noticed was that it loaded a “codex_apps” mcp service. Upon inspection it had a bunch of github api stuff which I don’t need, along with some plugin management. Adding the above to the config disables all apps, which is fine for how I use these tools, and should help avoid unnecessary token use.
