Support config.local.toml to override project-shared config.toml

[skoch13]

What variant of Codex are you using?

cli

What feature would you like to see?

It will be convenient to have an ability to override project codex settings, e.g. the project has shared MCP settings, but a team member wants to have it disabled or altered the tools available for the MCP server

Project-local config overrides are already supported. Refer to this section of the documentation.

@etraut-openai do you mean by -c cli flags? My request was mostly about the static config file override.

[etraut-openai]

No, I'm talking about .codex/config.toml config overrides.

@etraut-openai sorry I don't get it: I have project .codex/config.toml that I'd like to be able to overwrite. is there a way to achieve that?

[etraut-openai]

You have a user-level ~/.codex/config.toml file. You want to override that with a project-level config file. To do so, add a .codex/config.toml file in your project. Refer to documentation for details.

@etraut-openai I need to clarify my question. Here it is: I have a user-level configuration and a project-level configuration that sets an MCP server. I want to overwrite the project-level MCP configuration. How can I achieve that without using the -c flag?
