# tool si.act.capacity

Sets how many new leads one user can take in a period: The answer gives the new capacity, with how many the user holds and when it refills.

[figure: Over MCP, si.act.capacity takes CapacityInput and returns a card whose body is Capacity.]

The answer gives the new capacity, with how many the user holds and when it refills. The call needs the act grant at the brand rung.
