The Mongo.getDBs() method doesn't take any parameters.

Example

To list the available databases and metadata for the local MongoDB instance:

db.getMongo().getDBs()

The db.getMongo() method returns the connection to the current MongoDB instance. The Mongo.getDBs() output resembles:

{
 databases: [
   { name: 'admin', sizeOnDisk: Long("225280"), empty: false },
   { name: 'config', sizeOnDisk: Long("212992"), empty: false },
   { name: 'local', sizeOnDisk: Long("2400256"), empty: false },
   { name: 'test', sizeOnDisk: Long("303104"), empty: false }
 ],
 totalSize: Long("3141632"),
 totalSizeMb: Long("2"),
 ok: 1,
 '$clusterTime': {
   clusterTime: Timestamp({ t: 1640186473, i: 1 }),
   signature: {
     hash: Binary(Buffer.from("0000000000000000000000000000000000000000", "hex"), 0),
     keyId: Long("0")
   }
 },
 operationTime: Timestamp({ t: 1640186473, i: 1 })
 }
