Which vehicles are supported by this MCP server?

This MCP server supports GM vehicles from model year 2015 and newer that are equipped with OnStar connectivity. This includes most Chevrolet, GMC, Buick, and Cadillac models. You can verify compatibility by checking if your vehicle has the OnStar button or the myChevrolet/myGMC/myBuick/myCadillac app support.

Do I need an active OnStar subscription to use this server?

Yes, an active OnStar subscription is required to access the GM Connected Vehicle API. The specific features available depend on your OnStar plan. Remote commands like lock/unlock, remote start, and diagnostics require a plan that includes those capabilities. Check your OnStar plan details at my.chevrolet.com or contact OnStar support for more information.

How are vehicle commands secured?

All vehicle commands are authenticated through the GM Developer Portal OAuth flow. Each command requires a valid access token tied to your GM account. The MCP server does not store credentials; it uses the token provided during setup. Only vehicles linked to your GM account can be controlled, and all commands are logged in the OnStar activity history for audit purposes.
