For me it is not working in codex app. Despite having them in config.toml they just disappeared today from MCP servers config in the codex app.
codex version 26.325.31654
Looks like I've added mcp with wrong arguments which broke config.toml. But anyway it should be validated if user passes proper values to it.
Thanks for the bug report. This will be addressed in the next release.
