Claude Desktop model selector cannot display the model list

Quick fix

The Claude Desktop model list is controlled by the client. cc-switch local routing cannot make the developer-mode dropdown display models.

Symptom

Section titled “Symptom”
Error output
最后效果就是模型选择栏无法正常显示模型列表，由于使用第三方api，程序限制了不显示chat组件，因此目前影响的是cowork和code组件。目前未知为什么会这样
English translation

The final result is that the model selector cannot display the model list properly. Because a third-party api is used, the program restricts the chat component from being displayed, so cowork and code components are currently affected. It is currently unknown why this happens.

Cause

Section titled “Cause”

In cc-switch 3.14.1 on Windows, after setting the Claude Desktop developer-mode API endpoint to `http://127.0.0.1:15721`, the model selector did not show available models.

The maintainer explained that this is not a cc-switch bug: cc-switch local routing can handle sent API requests and map models, but cannot modify the Claude Desktop model-selection UI or its hard-coded validation logic. The original post did not provide a verifiable fix.

Fix

Section titled “Fix”

  1. Confirm that this is a Claude Desktop developer-mode limitation affecting the model list and component display; cc-switch routing cannot modify the client UI.

  2. For further investigation, refer to the link provided by the maintainer in the original discussion and follow the source Issue.
