toyota-mcp — Toyota & Lexus MCP server for Claude and other AI assistants

Ask your Toyota anything. toyota-mcp is a Model Context Protocol (MCP) server that connects a MyToyota or MyLexus Europe account to Claude, Claude Code, Cursor, VS Code or any MCP client — read your car's fuel level, range, location, trips and health, and send remote commands (lock, climate, charging) in plain language.

*"How much range is left?"* · *"Where is the car?"* · *"Is it locked?"* ·

*"What did the last trip consume?"* · *"What's my EV share this month?"* ·

*"Pre-heat the car for 8 am."* · *"Cheapest petrol near the car?"*

Requirements

• A MyToyota Europe account (the API covers Europe only — North America and Japan use entirely different systems).
• Sign in with toyota-mcp login, or with account credentials in the environment (that path cannot handle MFA/2FA).
• The vehicle must appear in the MyToyota mobile app.
• Python 3.11+ and uv for the zero-install uvx launcher (uvx fetches a suitable Python by itself).

Unofficial API. Toyota can change or break this API at any time without

notice. All API access is isolated behind pytoyoda, which historically absorbs

such breakage within days.

Quickstart

Sign in once

uvx toyota-mcp login

Your browser opens Toyota's own sign-in page. Toyota then redirects to an address the browser cannot follow (com.toyota.oneapp:/…) and shows an error — that is expected: copy that address from the address bar and paste it back. The session is saved in your operating system's credential store and refreshed automatically. Your password is never seen by this program and never written to a configuration file. uvx toyota-mcp logout forgets it.

Claude Desktop

Add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

{

"mcpServers": { "toyota": { "command": "uvx", "args": ["toyota-mcp"] } } }

Add options after toyota-mcp in args — for example ["toyota-mcp", "--addresses", "osm"] for postal addresses, or ["toyota-mcp", "--read-only"] to leave every remote command out.

Claude Code

claude mcp add --transport stdio toyota -- uvx toyota-mcp

Cursor, VS Code and other MCP clients

Any client that speaks stdio works with the same shape — command uvx, arguments ["toyota-mcp"]. In VS Code, add it to .vscode/mcp.json; in Cursor, to ~/.cursor/mcp.json.

First contact: the doctor

Before wiring anything into an MCP host, check your setup from a terminal:

uvx toyota-mcp doctor

It validates credentials, lists your vehicles, and prints which tools your specific car supports. Exit codes: 0 ok · 2 config · 3 auth · 4 no vehicle · 5 API error · 6 command rejected (probe).

Remote access — the "Connect" button

By default the server runs on stdio, next to the MCP client. Point it at a URL instead and it becomes a remote MCP server with its own OAuth 2.1 authorization server, so a client connects the way it connects to Gmail or GitHub: paste the URL, press Connect, approve in the browser.

toyota-mcp --http https://toyota.example.com

Nothing else to configure — connecting is signing in to Toyota:

1. Paste https://toyota.example.com/mcp into your client and press Connect.
2. The client registers itself and sends you to this server's sign-in page.
3. Enter the MyToyota email and password, then pick which vehicle to use when the account has several.
4. The client gets its token; the server keeps only Toyota's refresh token.

Signing in to the Toyota account *is* the proof that you own the deployment — there is no shared code and no user database. A server already connected to one account refuses a sign-in with a different one.

Toyota's own web login ends on a mobile deep link (com.toyota.oneapp:/…) that a browser cannot follow — on a phone it opens the MyToyota app instead — so the credentials are posted to Toyota by the server you run. They are never written down: only the refresh token Toyota returns is kept. Accounts with two-factor authentication cannot be used, as Toyota's vehicle API does not support them.

Run it on a machine of yours (a home server, a Raspberry Pi), behind a TLS-terminating proxy: the server refuses a non-https:// public URL other than localhost, because bearer tokens must not travel in clear. Registered clients and issued tokens are kept in ~/.local/state/toyota-mcp/oauth.json (mode 600) so a restart does not disconnect anyone; access tokens last an hour and refresh silently.

With Docker

docker build -t toyota-mcp --build-arg VERSION=0.3.0 .

docker run -d --name toyota-mcp -v toyota-mcp:/data -p 127.0.0.1:8787:8787 \ toyota-mcp --http https://toyota.example.com --host 0.0.0.0

A container has no credential store, so the session and the grants live in /data — keep it as a volume or signing in again is the price of a restart. TOYOTA_SESSION_FILE moves the session file elsewhere.

Authentication

Nothing has to be configured before the first use. A server with no account connected still starts and says what to do: over HTTP the Connect flow signs you in, otherwise toyota-mcp login does. toyota_list_vehicles and toyota_select_vehicle then choose the car from the conversation.

Toyota has no third-party API programme: there is no developer portal, no per-application token, and the mobile app signs in with your account password. This server therefore offers two ways in, and prefers the one where it never holds that password.

`toyota-mcp login`. Asks for the MyToyota email and password, signs in to Toyota, and keeps only the refresh token — in your operating system's credential store (Keychain, Windows Credential Locker, Secret Service), or in a file when there is none. The password is never written down, and never lands in an MCP host's configuration file.

Password in the environment. TOYOTA_USERNAME and TOYOTA_PASSWORD still work for unattended setups, but most MCP hosts store their env block as plain text on disk, so prefer toyota-mcp login.

Configuration

Features are command-line options, visible in toyota-mcp --help and in your host's args:

"toyota": {

"command": "uvx", "args": ["toyota-mcp", "--addresses", "osm", "--places", "home=43.6045,1.4440"] }

A local .env file works too (see .env.example). Credentials never touch disk otherwise; tokens live in memory only.

Available tools

Read tools are readOnlyHint: true. The remote commands below are registered unless the server runs with --read-only.

Remote commands

Registered by default; start with --read-only to leave them out:
