I’m trying to clarify MCP billing.
1. Remote Box MCP Server  
2. Self‑Hosted Box MCP Server  
The Self‑Hosted Box MCP Server uses the Box SDK internally, which makes the underlying API calls. I think this is chargeable.

Docs say:
• Partner Integration is non-chargeable.  
• Custom App is chargeable.

For case of remote box mcp server, will the API calls be marked as chargeable or not?
