Tessie MCP

Personal, self-hosted MCP access to Tessie. It is a Streamable HTTP server at /mcp, designed for one owner and protected by a static bearer token.

Setup

1. Generate a Tessie access token at https://dash.tessie.com/settings/api.
2. Create .env from .env.example and generate MCP_AUTH_TOKEN with openssl rand -base64 48.
3. Start the service: docker compose up -d --build.
4. Configure an MCP client with URL http://127.0.0.1:3000/mcp and header Authorization: Bearer <MCP_AUTH_TOKEN>.

TESSIE_API_KEY never leaves the server. Passing vin to get_vehicle selects and persists the default vehicle; later calls can omit it.

Tools

list_vehicles, get_vehicle, analyze_history, get_driving_path, and vehicle_command. History analysis defaults to 90 days. Autopilot/FSD values are Tessie's native autopilot_distance and historical autopilot telemetry; they do not uniquely prove FSD usage.

Remote access

For a temporary URL without a tunnel token, run the app locally then execute cloudflared tunnel --url http://127.0.0.1:3000. For a stable named tunnel, set TUNNEL_TOKEN in .env and run docker compose -f docker-compose.yml -f docker-compose.tunnel.yml up -d.

The app bearer token remains required even behind Cloudflare.

Nginx

Use examples/nginx.conf; preserve the Authorization header, disable buffering, and use long timeouts.

Caddy

Use examples/Caddyfile; it forwards headers and supports streaming by default.

Smoke check

curl http://127.0.0.1:3000/healthz verifies liveness. The server has no command-line operation that invokes vehicle commands.
