MongoDB

Description

The MongoDB node runs operations on a MongoDB database. It is the equivalent of n8n’s MongoDB node, so imported flows that used it are mapped to this node (no longer left as a placeholder).

Configuration

Parameter	Type	Required	Description
connectionString	text	No	Full connection string (mongodb://user:pass@host:27017/db). If set, host/port/credentials are ignored
host / port	text	No	Host and port (default 127.0.0.1:27017)
database	text	No	Database
user / password	text	No	Credentials
collection	text	Yes	Collection to operate on
operation	select	Yes	find, findOne, insert, update, delete, aggregate, count
query	textarea (JSON)	No	Filter for find/update/delete/count; pipeline for aggregate
documents	textarea (JSON)	No	Document(s) to insert (object or array)
update	textarea (JSON)	No	Update ({ "$set": {...} }; a plain object is wrapped in $set)
limit	number	No	Result limit (find)

Output

{ "nextModule": "next_module", "data": { "result": [ /* documents or operation result */ ] } }

Notes

• Supports dynamic variables {{variable}} in all fields.
• The connection is closed automatically when done.
• When importing from n8n, the connection is left empty (credentials live outside n8n’s JSON): fill it in after importing.
