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: KEYBAN_API_KEY, KEYBAN_APP_ID, KEYBAN_INVITE_KEY, KEYBAN_WALLET_ADDRESS, KEYBAN_NETWORK, KEYBAN_BASE_URL, KEYBAN_DKG_BLOB, MCP_LOG_FILE, MCP_LOG_LEVEL. 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.
