Log activity
Log a call, meeting or custom activity on a record.
MCP tool copper_crm_write → log_activity
write Confirm
Adds an entry to the record's Activity Log, as Log Activity does. Phone Call and Meeting count in interaction stats and the Activity by User report, To-do does not, and a custom type counts only if it was created as an interaction. Completing a task does not log an activity by itself. The entry is visible to your team. By default you confirm each call; you can switch that off for this tool.
