in the cloud
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: KSEF_SESSION_TOKEN, KSEF_NIP, KSEF_ENVIRONMENT, KSEF_TIMEOUT. Fill them in before you deploy.
Clients connect to the service's https://…koyeb.app address plus /mcp.

-
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.
