This PR adds the following: * A getAuthStatus method on the mcp server. This returns the auth method currently in use (chatgpt or apikey) or none if the user is not authenticated. It also returns the "preferred auth method" which reflects the `preferred_auth_method` value in the config. * A logout method on the mcp server. If called, it logs out the user and deletes the `auth.json` file — the same behavior in the cli's `/logout` command. * An `authStatusChange` event notification that is sent when the auth status changes due to successful login or logout operations. * Logic to pass command-line config overrides to the mcp server at startup time. This allows use cases like `codex mcp -c preferred_auth_method=apikey`.
codex-protocol
This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex mcp.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
