Our internal MCP system utilizes a IP whitelisting to ensure no unauthorized systems can even attempt to connect. Regular authentication happens beyond that point.

However, we cannot find any details about which IP addresses the ClickUp MCPs connect from. Removing the whitelisting it works. We can add IPs one by one, but that's not a great approach.

Support was not able to provide them and recommended creating a feature request so this can hopefully get actioned, or responded to.
