    koyeb
    deploy to koyeb

    The form opens with CHANGE_ME for each value you supply: GEMINI_API_KEY, GEMINI_IMAGE_MODEL, GEMINI_OUTPUT_DIR, GEMINI_INPUT_DIR, GEMINI_UPLOAD_DIR, GEMINI_REFERENCE_DIR, GEMINI_TIMEOUT_MS, GEMINI_HEARTBEAT_MS, GEMINI_CHAIN_RETRY_MS, GEMINI_DEBUG, GEMINI_RATE_CARD. Fill them in before you deploy.

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

    azure
    deploy to azuretemplate

    A Container Apps environment with one app per server, each with HTTPS ingress and one replica. The portal asks for each value you supply as a secure parameter; the deployment's outputs list the endpoints.
