    one click: the provider's deploy form opens filled in, in your own account
    koyeb

    The form opens with CHANGE_ME for each value you supply: CUSTOM_DOMAIN_API_URL, CUSTOM_DOMAIN_API_KEY. Fill them in before you deploy.

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

    azure

    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.
