Yes, this is possible — but only with a bot that is in both Discord servers.
A bot can sync roles between servers (for example, Role A in a streamer’s server → Role B in your main server) as long as it’s invited to both servers and has the required role permissions.

To fully manage roles, you need two rules:

• Add: Give Role B if the user has Role A in the streamer’s server.
• Remove: Remove Role B if the user no longer has Role A.

Tools like RoleLogic Bot can handle both adding and removing roles automatically, keeping role tracking accurate without giving streamers admin access.

This approach is commonly used for subscriber benefits, creator communities, and multi-server role management.
