in the cloud
one click: the provider's deploy form opens filled in, in your own account- koyeb
-
Koyeb builds the repository's Dockerfile from branch main; change the branch in the form if the default one has another name.
Clients connect to the service's https://…koyeb.app address plus /mcp.
- cloud run
-
Cloud Shell clones the repository, builds its Dockerfile and deploys it to Cloud Run.
Cloud Run sends requests to $PORT (8080); the recipe expects :8000, so the server has to read PORT, or set the container port on the service afterwards.
