Copilot for JetBrains: admin-set default models, one-click fixes from diagnostics, and an off switch for MCP autostart
What is it?
This is an update to the GitHub Copilot plugin for JetBrains IDEs. Enterprise admins can now use managed settings to pick the default agent model for new conversations. A Fix action in the diagnostics menu opens inline chat and repairs the issue in agent mode. A new setting stops Copilot and Claude MCP servers from starting automatically, and there are smaller touches too, like copying and editing your own chat messages.
Why does it matter?
Teams that want to keep cost and quality consistent need control over the default model, and JetBrains users now have that lever too. Turning off MCP autostart makes it easier to keep unreviewed tools from spinning up on their own. Support for JetBrains IDE 2025.1 has ended, so check which IDE versions your org runs.
Maturity
GAIt looks like a routine plugin release, but the changelog gives neither a GA/preview label nor a plugin version number. Managed default models only apply where enterprise managed settings are in place.
How to track it
- GA or preview status and the plugin version: check the Copilot for JetBrains posts on the GitHub Changelog and the JetBrains Marketplace plugin page.
- Docs for managed default models: enterprise admins should watch for updates to the Copilot admin settings guide in GitHub Docs.
- Changes to IDE support: watch the GitHub Changelog for the next end-of-support notice.
