## Open Chat settings

Use **Settings** in the Chat header or welcome screen to choose how Inspector
connects to Copilot. Settings are saved only when you select **Save**.

![Copilot Chat Settings showing the Usage-limited free trial provider, selected backend model, backend status refresh, expanded advanced settings, and Save and Close actions.](https://inspector.4111778.xyz/assets/captures/copilot-chat-settings-dialog.png)

## Choose a provider

The **Provider mode** list has two supported choices:

* **Usage-limited free trial** is the default. It does not require GitHub
  Copilot sign-in and shows remaining trial credit when that information is
  available.
* **GitHub Copilot Subscription** uses the packaged Copilot CLI and your
  GitHub Copilot sign-in for regular use.

Select the provider that matches the account and usage you intend to use, then
continue with the matching settings below.

## Sign in to GitHub Copilot

1. Select **GitHub Copilot Subscription** in **Provider mode**.
2. Select **Save**. The provider setting must be saved before sign-in starts.
3. Reopen **Settings** if needed, then select **Start Copilot sign-in**.
4. Keep the terminal open, copy the one-time code it displays, and enter the
   code in the browser page after signing in.
5. Return to Settings and wait for Inspector to verify the sign-in and refresh
   the available models.

The packaged Copilot CLI stores credentials for the current Windows user. Do
not enter credentials into the Chat prompt. Use **Sign-in help** for the linked
GitHub OAuth instructions.

When the account is authenticated, choose a model in the **Model** list and
select **Refresh** when the account's model catalog changes. Select **Sign
out** to remove the saved Copilot CLI sign-in.

## Review advanced settings

Expand **Advanced settings** when you need to inspect or change supporting
options:

* **Inspector MCP endpoint** is read-only and is derived from the current
  Inspector MCP server settings.
* **Reasoning effort** controls the configured reasoning setting passed to the
  Copilot session.
* **Enable Copilot CLI logging** enables runtime logs. Use **Open logs** to
  open the log folder when diagnosing a connection or session problem.
* **Allow agent to use PowerShell terminal** makes PowerShell tools available
  to the agent. Terminal commands still require approval before they run.

In free-trial mode, use **Refresh backend** when the connection or available
model list needs to be checked again. The status text reports whether the
connection succeeded or why metadata is unavailable.

Select **Save** after changing any setting. The status text reports whether the
settings were saved or could not be saved.
