codex startup_timeout_sec cannot be set manually (Codex)

Quick fix

Do not use CC Switch to manage Codex MCP instances that require a custom startup_timeout_sec for now.

Symptom

Section titled “Symptom”
Error output
编辑中输入 startup_timeout_sec = 60 保存后不生效
English translation

After entering startup_timeout_sec = 60 in the editor and saving, the setting does not take effect.

Cause

Section titled “Cause”

The maintainer confirmed that this is caused by the special format of the Codex configuration file; supporting custom fields like this would require substantial refactoring.

A user suggested appending TOML configuration in additional information or adding a field to the MCP JSON, but the original issue did not confirm that either approach was implemented or works. The issue was automatically closed due to inactivity and cannot be treated as fixed.

Fix

Section titled “Fix”

  1. If you need to set a custom `startup_timeout_sec` for an MCP, do not use CC Switch to manage that MCP for now.

  2. Follow the source issue; the original post does not provide a verifiable way to save this field in CC Switch.

FAQ

Section titled “FAQ”
What if it also cannot be written through the general configuration?
This is the same limitation. The maintainer said it is caused by the special format of the Codex configuration file, and the original post provides no verifiable solution within CC Switch.
Can I add "startup_timeout_sec": 120 to the MCP JSON in the editor?
This was a user suggestion. The original post did not confirm that it has been implemented or that the value is saved successfully.
