Update opportunity
Move an opportunity to another stage or set its status, loss reason and close date.
MCP tool copper_crm_write → update_opportunity
write Confirm
Changes only the fields you pass. Set status to Won, Lost, Abandoned or Open. For Lost, pass loss_reason from list_pipelines, as the Loss Reasons box in Copper asks for one, and set close_date to today to keep reports accurate. Other users see the change, and Workflow Automation rules may fire on it. By default you confirm each call; you can switch that off for this tool.
