Add call note
Add text to the Notes field of one call.
MCP tool aircall_write → add_call_note
write Confirm
Adds the text to the call's Notes field, after any note already there. Teammates on the same line can read the note. A note syncs to a connected CRM after the call ends, and once synced it cannot be edited from Aircall. By default you confirm each call; you can switch that off for this tool.
Parameters
| Name | Type | Description |
