To set up a MongoDB update tool to modify user emails based on phone numbers, you’ll need to:

1. Use the MongoDB node in n8n with “Update” operation selected

2. In the “Update Key” field, enter `phoneNumber` (or your exact field name)

3. In the “Fields to Update” section, add `email` as the field and map the new email value

The key is ensuring your update query matches documents where `phoneNumber` equals your input value, then updates the `email` field. Would you like me to show the exact JSON structure for the update operation?
