Create task
A task with a due date, work type and optional deal, assignee and customer.
MCP tool teamleader_write → create_task
write
Creates a task. A title, a due date and a work type are required, because Teamleader asks for a work type on every task. Link it to a deal or a customer and assign it to a user. It is the same task you would add from a deal. It sends no email to a customer and is deleted in Teamleader if it is wrong, so it does not wait for your OK.
