Tessie MCP Server

Control and monitor your Tesla from any MCP-compatible AI assistant — including Claude, Cursor, and more.

An MCP (Model Context Protocol) server that bridges AI assistants to the Tessie API, giving you natural-language control of your Tesla vehicle. Ask Claude to check your battery, preheat the cabin, lock the car, or pull charging history — all in plain English.

🔧 Configuration

Environment Variables

Authentication and preferences are configured entirely via environment variables — no secrets ever touch source code.

Variable	Required	Description
TESSIE_API_TOKEN	✅ Yes	Your Tessie API token
TESSIE_DEFAULT_VIN	Optional	Default VIN when not specified per-call
TESSIE_DISTANCE_FORMAT	Optional	mi or km — applies to all distance tools
TESSIE_TEMP_FORMAT	Optional	f or c — applies to all temperature tools
TESSIE_PRESSURE_FORMAT	Optional	psi, bar, or kpa — applies to tire pressure

Per-call parameters always override the env var defaults.

😴 Auto-Wake

All vehicle commands automatically wake a sleeping vehicle before executing — no need to call wake_vehicle manually first.

• If the vehicle is already awake, commands execute instantly with zero added latency
• If the vehicle is asleep, the server sends a wake command and polls every 3 seconds until the vehicle is awake (up to 90 seconds), then sends your command
• Read-only data tools (get_battery, get_location, etc.) use cached data by default and do not wake the vehicle

📡 MCP Resources

In addition to tools, this server exposes vehicle data as MCP Resources — structured data that AI clients can read as contextual documents:

URI	Description
tessie://vehicles	Fleet overview — all vehicles on the account
tessie://{vin}/state	Full live vehicle state (charge, climate, drive, config)
tessie://{vin}/status	Current awake/asleep status

Resources are accessible in Claude Desktop and other MCP clients that support the resources protocol.

💬 Example Prompts

Once configured, try asking your AI assistant:

• "How is my Tesla doing right now?" → uses get_full_status
• "What's my battery level and estimated range?"
• "Where is my car parked right now?"
• "Start the climate and set it to 72°F" (auto-wakes if needed)
• "Lock the car and turn on Sentry Mode" (auto-wakes if needed)
• "Show me my drives from this week"
• "Open the frunk"
• "What's the tire pressure on all four tires?"
• "Set my charge limit to 80%"
• "Tag all my drives this month as business"

🔒 Security Notes

• Your Tessie API token is passed as an environment variable — never stored in code or config files
• The .gitignore in this repo explicitly excludes .env files
• If your token has been exposed, rotate it immediately at dash.tessie.com/settings/api
• All vehicle commands are authenticated with your personal token — only you can control your vehicle
