The ClickUp API has an endpoint that returns all tasks from a list with custom fields included in a single call. The issue is that the ClickUp MCP connector I'm working with doesn't expose that endpoint — it only gives me:

filter_tasks → returns compact results (no custom fields)

get_task → returns full detail but only one task at a time

The 91-call problem is a limitation of the connector, not the ClickUp API itself.

There's no bulk "get tasks with custom fields" tool in the connector.

The ClickUp MCP connector doesn't expose that endpoint. It only offers filter_tasks (compact, no custom fields) and get_task (full detail, one at a time)
