What is the General Motors MCP Server?
What you can do
Connect AI agents to the General Motors Connected Vehicle API for comprehensive car management:
- List registered vehicles to manage fleets or personal garages
- Track GPS location to find parked cars or monitor fleet movement
- Monitor diagnostics including oil life, battery voltage, and check engine status
- Check EV charge levels and estimated range for electric vehicles
- Lock and unlock doors remotely for security or guest access
- Start and stop engines remotely to pre-condition cabin temperature
- Flash lights and sound horn to locate vehicles in crowded areas
- Send navigation destinations directly to the infotainment system
How it works
1. Register at GM Developer Portal and create an application
2. Authenticate via OAuth to obtain an access token for your vehicle
3. Ask your AI agent to check status, run diagnostics, or send commands
4. Natural language commands replace the myChevrolet/OnStar app navigation
Who is this for?
Perfect for GM vehicle owners, fleet managers, service advisors, and roadside assistance teams. Let AI agents automate morning warm-ups, monitor tire pressure for safety, track mileage for maintenance schedules, and locate vehicles. Ideal for drivers who want to integrate their car into their smart home or AI assistant workflow for seamless mobility management.

Frequently asked questions
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.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
