    The form opens with CHANGE_ME for each value you supply: WHATSAPP_BACKEND, BAILEYS_SESSION_DIR, LOG_LEVEL, LOG_STDERR_LEVEL, WHATSAPP_HEADLESS, WHATSAPP_NO_SANDBOX, BROWSER_EXECUTABLE_PATH, WHATSAPP_SESSION_DIR, WHATSAPP_PAIRING_PHONE_NUMBER, FFMPEG_PATH, WA_WEB_VERSION, HEALTH_CHECK_INTERVAL_MS, TOOL_READY_TIMEOUT_MS, MCP_HTTP_PORT, MCP_HTTP_HOST, MCP_OAUTH. Fill them in before you deploy.

    Clients connect to the service's https://…koyeb.app address plus /mcp.
