Start the GenAI Engine backend server and frontend UI. Use when you need to launch the API server and the frontend locally.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Start GenAI Engine Backend Server ## Step 1 — GPT Key Gate Use the Read tool to read `./genai-engine/.env`. Check that `GENAI_ENGINE_OPENAI_GPT_NAMES_ENDPOINTS_KEYS` is present and has a non-empty value (not just `GENAI_ENGINE_OPENAI_GPT_NAMES_ENDPOINTS_KEYS=` with nothing after the `=`). If the value is missing or empty: - **STOP immediately. Do not proceed to Step 2.** - Tell the user: "Setup cannot continue. Please open `genai-engine/.env` and set `GENAI_ENGINE_OPENAI_GPT_NAMES_ENDPOINTS_KEYS` using the format: `MODEL_NAME::ENDPOINT_URL::API_KEY` (e.g. `gpt-4o::https://api.openai.com/::sk-...`). Run the skill again once the key is set." ## Step 2 — Delegate Startup to Bash Sub-Agent Only proceed here if Step 1 passed. Spawn a Task sub-agent with subagent_type="Bash" and the following self-contained prompt: --- Start the GenAI Engine backend and frontend. Report success or failure for each step. **Step 1 — Verify PostgreSQL is running:** ```bash cd genai-engine && docker compose ps db ``` If not running or unhealthy, start it: ```bash cd genai-engine && docker compose up -d db && sleep 3 ``` **Step 2 — Start the backend server in the background:** ```bash …

How to install
mdr add arthur-ai/arthur-engine/start-genai-backend@sha256:56df731040946b10The line at the top of this page pins the label git:20260407.50741a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
