Tesla MCP Server

What a Tesla MCP server is, the 40 tools mytesla.io exposes, which AI clients it works with, and how the Fleet API connection actually works.

A Tesla MCP server lets any MCP-compatible AI assistant — Claude, ChatGPT, Cursor, VS Code, or a custom agent — read your car's status and send it commands, through Tesla's official Fleet API. mytesla.io is one: this page explains what that means and how it actually works.

What MCP is, briefly

Model Context Protocol is the open standard AI assistants use to call external tools during a conversation. Instead of every AI vendor building its own one-off Tesla integration, an MCP server exposes a fixed set of tools once, and any MCP-aware client — Claude, ChatGPT, Cursor, VS Code, or your own agent — can call them the same way. You don't install a Tesla-specific plugin per assistant; you point your assistant at one URL.

How mytesla.io's server works

  1. You connect your Tesla to mytesla.io through Tesla's own OAuth consent flow — the same kind of authorization Tesla's own app uses, via the official Fleet API and Vehicle Command Protocol.
  2. mytesla.io runs as a hosted MCP server at https://mcp.mytesla.io/mcp, speaking Streamable HTTP MCP with OAuth 2.1 authorization.
  3. Your AI client connects to that URL, authenticates as you, and gets a list of available tools.
  4. When you ask something in plain English, the AI decides which tool(s) to call and with what arguments, calls them, and reports back.

No location, drive, or charge history is stored on mytesla.io's side — data is fetched live per request and handed back. See the privacy policy for the full detail.

The 40 tools

  • Reads: get_vehicles, get_vehicle_status, get_credit_balance, wake_vehicle
  • Climate: start_climate, stop_climate, set_cabin_temperature, max_defrost, set_seat_heater, set_steering_wheel_heater, set_seat_cooler, set_climate_keeper_mode, set_cabin_overheat_protection
  • Charging: start_charging, stop_charging, set_charge_limit, set_scheduled_charging, set_scheduled_departure, set_charging_amps, open_charge_port, close_charge_port
  • Access & cargo: lock_vehicle, unlock_vehicle, actuate_trunk, control_windows, sun_roof_control
  • Alerts: honk_horn, flash_lights
  • Navigation & smart-home: share_destination, trigger_homelink
  • Security: set_sentry_mode, set_valet_mode, reset_valet_pin, set_speed_limit, speed_limit_activate, speed_limit_deactivate, speed_limit_clear_pin
  • Software: schedule_software_update, cancel_software_update
  • Feedback: report_bug (always free)

Every tool maps directly to a real Fleet API or Vehicle Command Protocol call — there's no "do anything" escape hatch, so the AI is bounded to exactly this list.

Supported clients

Any client that speaks Streamable HTTP MCP with OAuth 2.1 works. In practice, that's:

The server publishes standard OAuth discovery metadata at https://mcp.mytesla.io/.well-known/oauth-protected-resource and .../.well-known/oauth-authorization-server, and an MCP server card at https://mytesla.io/.well-known/mcp/server-card.json, so clients that support autodiscovery can find and configure it automatically.

Pricing

Access is a flat monthly subscription, not per-call metering:

  • Driver — $4.99/month, 500 credits
  • Driver Max — $9.99/month, 1,500 credits

Most commands cost 1 credit; waking a sleeping car costs 10 (Tesla itself rate-limits and prices wake calls more heavily). get_vehicles and report_bug are always free. Full detail in the billing policy.

Which Teslas are supported

Any Model S, 3, X, or Y that supports Tesla's Fleet API and Vehicle Command Protocol — in practice, essentially every Model S/3/X/Y from 2018 onward. Some tools are trim-specific (sun_roof_control on older panoramic-roof Model S, set_seat_cooler on ventilated-seat trims) — the AI tells you when a command doesn't apply to your car rather than failing silently.

FAQ

Is this an official Tesla product? No. mytesla.io is an independent product operated by Embay, LLC, built on Tesla's official Fleet API — but not built, endorsed, or operated by Tesla, Inc.

Does the AI ever get more access than I explicitly grant? No. The OAuth scope you approve on Tesla's consent screen sets the ceiling; mytesla.io can't request anything beyond it, and it only exposes the 40 tools listed above regardless of what the underlying Fleet API supports.

Can I use my own MCP client instead of Claude or ChatGPT? Yes — anything that supports Streamable HTTP MCP with OAuth 2.1 can connect to https://mcp.mytesla.io/mcp. The full setup guide has more on authentication.
