Quick-Start Guide to mLab

Step 1: Set up a mLab account

To get started with mLab, you must first create your free mLab account. When that’s complete, you can add as many database subscriptions as you want.

For additional information about managing your mLab account users, contacts, and billing, see mLab Account Setup.

Step 2: Create a database subscription

After you’ve created your account, add a new database subscription. Get started quickly at no cost with a free Sandbox database.


For detailed steps on how to add a subscription, see Database Subscriptions. For a discussion on how to choose the right plan for your subscription, see Plans and Data Centers.

Step 3: Connect to your new database

In a terminal window, connect to your database using the mongo shell (the command will look similar to the following example):

% mongo ds012345.mlab.com:56789/dbname -u dbuser -p dbpassword

You can grab your connection info after logging into your account and navigating to the database’s home page:


To view detailed connection instructions, troubleshooting tips, and alternate connection methods, see Connecting to Your Database.

Step 4: Load some data

Here’s a quick exercise that tests an insertion into your new database:

  1. Assuming you successfully connected using the mongo shell in the previous step, run the following command:

     > db.mynewcollection.insert({ "foo" : "bar" })
  2. Next, run the command in the first line below and confirm that the shell output matches the second line (your “_id” value will be different):

     > db.mynewcollection.find()
     { "_id" : ObjectId("526705b4a3559a176784b4af"), "foo" : "bar" }
