How to Use the General Motors MCP in Windsurf

Q: How do I configure the General Motors MCP Server in Windsurf?

Open /.codeium/windsurf/mcpconfig.json or use the Settings UI under Cascade. Add the server details to the mcpServers object and click Refresh in the MCP panel. Cascade automatically discovers the 14 vehicle tools upon connection.

Q: Why does the horn tool fail in my agent?

The flashhorn tool requires an active network connection to the vehicle's telematics module. If the car is parked in an underground garage with no cellular signal, the command times out.

Connect Windsurf to your General Motors fleet and let Cascade autonomously chain diagnostics, routing, and remote commands.

Autonomous Fleet Diagnostics in Windsurf

The `get_vehicle_diagnostics` tool pulls raw health data from a connected GM vehicle directly into your Windsurf workspace. You drop a prompt asking Cascade to check the fleet's readiness, and the agent automatically starts by calling `get_vehicles` to grab every VIN associated with your account. It iterates through the list, pulling active tire pressure and oil life stats without you writing a single API request. Cascade handles the data mapping on its own. If you need a quick dashboard of EVs needing a charge, the agent hits `get_charge_status` and formats the battery levels into a markdown table. You set the goal, and Windsurf executes the sequence.

General Motors MCP Server Physical Controls

The `start_vehicle` tool triggers the remote engine start sequence on a specific VIN. Windsurf can chain this with environmental checks—if you ask Cascade to prep the car for a trip, it can read a local weather API, decide to fire up the engine for climate control, and verify the command status. Physical write commands require explicit VIN targeting. If a test fails or you need to abort, Cascade can immediately call `stop_vehicle`. You get direct control over physical hardware straight from the editor.

Send Destinations and Track Movement

The `get_vehicle_location` tool fetches real-time GPS coordinates for any targeted vehicle. You can ask Windsurf to build a tracking script, and Cascade will write the polling logic while testing the endpoint against your car. Planning a test drive route takes one step. The agent uses `send_turn_by_turn` to push latitude, longitude, and address data straight to the built-in navigation system. By the time you walk out to the driveway, the route is already loaded on the dashboard.

Setup guide

Set up General Motors MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the General Motors MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my General Motors payment history." If connected, Cascade will call the General Motors tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about General Motors MCP in Windsurf

Open `~/.codeium/windsurf/mcp_config.json` or use the Settings UI under Cascade. Add the server details to the `mcpServers` object and click Refresh in the MCP panel. Cascade automatically discovers the 14 vehicle tools upon connection.

Yes. Cascade excels at multi-step autonomous execution. You can ask it to prep a vehicle, and it will sequentially call `lock_doors`, `start_vehicle`, and `get_fuel_level` without pausing for permission between steps.

Almost all tools require a valid VIN. You should start your workflow by asking the agent to run `get_vehicles` to pull the available IDs tied to your account.

The `flash_horn` tool requires an active network connection to the vehicle's telematics module. If the car is parked in an underground garage with no cellular signal, the command times out.

The server processes raw latitude and longitude coordinates when executing `get_vehicle_location`. Vinkius runs this MCP Server in an ephemeral V8 Isolate Sandbox, meaning your vehicle's physical location is completely wiped from memory the millisecond the connection closes.
