liauto

liauto is a CLI for Li Auto vehicle APIs. It covers device activation/login, real-time status, monthly travel history, control commands, an HTTP API server, and an MCP server.

Build

go build ./...
go vet ./...
go test ./...

Commands

liauto activate          # activate the current device (first activation or re-activation)
liauto login             # device login, prints an OAuth URL, then persists the pasted token JSON
liauto vehicles          # list cached vehicles
liauto status <VIN>      # query vehicle state (--json/--raw)
liauto travel <VIN> [YYYY-MM]   # monthly travel history; with YYYY-MM, that month's detail
liauto control <VIN> <action>   # lock/unlock/find/wake + ac <on|off|auto|temp|fast-cool|fast-heat> + seat-vent/seat-heat [pos] <1-3|off> + wheel-heat <on|off> + window [pos] <0-99> + trunk <open|close> (action: result <id>)
liauto version           # print version
liauto serve             # HTTP API server (default 127.0.0.1:18001; --addr/--token/--allow-control)
liauto mcp               # MCP server, stdio (default) or --transport http (default 127.0.0.1:18002)

Run liauto with no arguments (or liauto <unknown>) to print the command list.

Global flags: --json (JSON output), -v / --verbose (verbose logging to stderr).

Exit codes: 0 success, 1 user input error, 2 network failure, 3 HTTP non-200, 4 activation failure, 5 config permission/corrupt, 6 missing/invalid/expired activation code.

Activation code

Running any liauto command except version requires a valid activation code, set as an environment variable:

export LICLI_CODE=<activation code>
liauto login       # one-time: prints an authorization URL, then paste the token JSON from the browser's F12 developer tools
liauto vehicles    # list vehicles

A code is issued by the tool's publisher (offline license-keygen). It is an Ed25519-signed token: the binary only verifies it with the built-in public key and cannot forge codes. Missing/invalid/expired codes exit with code 6.

HTTP API server (serve)

liauto serve runs a foreground HTTP server (default 127.0.0.1:18001, override with --addr) exposing JSON endpoints for the vehicles/status/travel/control surface. Bind to a loopback address, set --token, or pass --allow-control to enable the control endpoints.

MCP server (mcp)

liauto mcp serves the Model Context Protocol over stdio (default) or Streamable HTTP (--transport http, default 127.0.0.1:18002). It exposes six tools: vehicles, status, travel_months, travel_month, control, control_result. The two control* tools are enabled by default under stdio; under --transport http they require --allow-control or --token.

Configuration

Credentials are stored under the XDG config directory (~/.config/licli by default, or $XDG_CONFIG_HOME/licli) with 0700 directory and 0600 file permissions:

• device.json — activated device + key suite
• auth.json — API token, ID token, refresh token, expiry
