Connect to Your MongoDB Deployment
On this page
This page outlines how to use MongoDB for VS Code Extension to connect to a MongoDB host. You can connect to a standalone, replica set, or sharded cluster host.
Note
MongoDB Atlas
If you need to create a MongoDB host, consider using MongoDB Atlas. Atlas is a cloud-hosted database-as-a-service which requires no installation, offers a free tier to get started, and provides a copyable URI to easily connect VS Code Extension to your deployment.
To create a cluster on the Atlas free tier, run the command
MongoDB: Open Overview Page
in the Visual Studio Code Command
Palette and then click Create free cluster.
To create an Atlas cluster using a Terraform template included with VS Code Extension, see Create an Atlas Cluster from a Template using Terraform.
If you need to install VS Code Extension, see Install MongoDB for VS Code Extension for instructions.
Considerations
When connecting VS Code Extension to a replica set, use either the replica set SRV record or Replica Set Name when filling in your connection information. It is not recommended to connect directly to an individual replica set member.
You can't connect VS Code Extension directly to an analytics node.
VS Code Extension appends the
appName
connection string option with a value ofmongodb-vscode <version>
for all deployment connections.
Create a Connection
VS Code Extension provides two options to connect to your deployment:
Connection Method | Description |
---|---|
Connect with Connection String | This method is faster and easier than
using the advanced connection settings. Use this option
if your deployment is hosted on Atlas or you already have a
connection string for a deployment available. |
Advanced Connection Settings | This method lets you build a connection string with a form.
Use this option if you need to customize the connection
string and want to see available connection options. |
Note
To specify where VS Code Extension connections are saved, use the Default Connection Saving Location setting.
When you provide a connection string, VS Code Extension supports most Connection String Options supported by MongoDB.
Obtain your connection string.
You can use either the Standard Connection String Format or the DNS Seedlist Connection Format.
To obtain the connection string for an Atlas cluster:
Navigate to your Atlas Clusters view.
Click Connect for your desired cluster.
Click Connect with MongoDB Compass.
Copy the provided connection string.
To learn how to format the connection string for a deployment which is not hosted on Atlas, see Connection String URI Format.
Open the Visual Studio Code Command Palette.
Open the Visual Studio Code Command Palette to paste your connection string and connect to your cluster. You can open the Command Palette in one of the following ways:
Select the MongoDB icon from the left side menu bar in VSCode.

VS Code Extension does not support the following connection options:
CSFLE In-Use Encryption
Kerberos Authentication
The General tab contains the following options:
Option | Description | ||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Connection Type | Type of connection. Select your connection type from the tabs for specific instructions for defining that connection type: For a Standalone, specify the following:
Click to specify additional hostnames and associated ports. For a replica set, specify the following:
Click to specify additional hostnames and associated ports. For an SRV Record, specify the Hostname. You do not need to specify a port. SRV connection strings have a prefix of
For example: If the following is your SRV connection string for your MongoDB deployment:
Then, in VS Code Extension, you would specify your Hostname as:
| ||||||||||||||||||||||
Authentication | Authentication to use if the deployment requires authentication. Atlas clusters use Username / Password authentication. Select your authentication method for specific instructions: Select Username / Password if the deployment uses MongoDB-CR, SCRAM-SHA-1, or SCRAM-SHA-256 as its authentication mechanism. Provide the Username, Password, and Authentication Database to authenticate the user. Select OIDC if the deployment uses OpenID Connect as its authentication mechanism. Provide the following information:
This is a less secure authentication flow that can be used as a fallback when browser-based authentication is unavailable. Select X.509 if the deployment uses X.509 as its authentication mechanism. If selected, you must provide the Username to authenticate the user. If you are using Atlas-managed certificates , your username must be prefaced by "CN=" per RFC 2253. For example, the username "X509User" must be provided as "CN=X509User". Select LDAP if the deployment uses LDAP as its authentication mechanism. If selected, you must provide the Username and Password to authenticate the user. Select AWS IAM if the deployment uses AWS IAM as its authentication mechanism.

If you are connecting to your deployment using TLS/SSL or an SSH tunnel, refer to the following tabs for specific instructions:
This option directs VS Code Extension to connect to your MongoDB deployment via TLS/SSL. You can select one of the following SSL options:
Option | Description | ||||||||
---|---|---|---|---|---|---|---|---|---|
System CA/Atlas Deployment | Connect to
MongoDB Atlas. | ||||||||
Server Validation | VS Code Extension validates the identity of the deployment. If selected, you must provide:
| ||||||||
Server and Client Validation | The deployment performs certificate validation from its clients and VS Code Extension validates the identity of the deployment. If selected, you must provide:
| ||||||||
Unvalidated (Insecure) | Use TLS/SSL without any identity validation. |
Tip
For production use, your MongoDB deployment should use valid certificates generated and signed by a single certificate authority. You or your organization can generate and maintain an independent certificate authority, or use certificates generated by a third-party TLS/SSL vendor.
This option directs VS Code Extension to connect to your MongoDB deployment via an SSH tunnel. The tunnel automatically starts when you connect to MongoDB and stops when you disconnect.
In the SSH Tunnel dropdown, choose either a password or an identity file to provide authentication. Once you select your identification method, specify the following options:
SSH Hostname | Enter the bastion (jumpbox) hostname. This is the
unique identifier (Fully Qualified Domain Name, or
FQDN) for the machine to be accessed. |
SSH Tunnel Port | Provide the port used for the SSH connection. This
defaults to 22, the standard port for SSH. |
SSH Username | The username of the profile to log into on the remote
system. This will be the user for which you want to
establish the SSH connection. |
SSH Identity File | Select the file from which the identity (private key) for SSH public key authentication is read. Unix or OS X: If using OpenSSH, identity files are
found in the
On Windows, the location of the identify files depends on your choice of SSH client, such as PuTTY. |
SSH Passphrase | If your private key is encrypted, provide the
passphrase used to decrypt your private key (stored
in the specified identity file). A passphrase
provides an extra layer of security for an SSH
connection. |
SSH Password | The password used to secure the SSH connection.
This is required if you are not using an identity file. |
To use an SSH tunnel through a bastion host, the SSH
configuration on the bastion host must allow TCP port
forwarding; i.e., the AllowTcpForwarding
directive in
the /etc/ssh/sshd_config
file is set to yes
. If
AllowTcpForwarding
is not set to yes
, set to yes
and restart the SSH daemon (sudo service sshd restart
).
Instead of creating the SSH tunnel using VS Code Extension, you can also create the tunnel manually from the command line:
ssh -L <local_port>:<mongodb_hostname>:<mongodb_port> \ <user>@<bastion_hostname> -fN
Example
If you have a deployment running on
hostname-a.com
on port 27017, and the
bastion host is hostname-b.com
with user name
ec2-user
, you can build the tunnel via
ssh -L 27000:hostname-a.com:27017 ec2-user@hostname-b.com -fN
Using this SSH tunnel, you can now connect VS Code Extension (or
the mongo
shell) to
localhost:27000
to connect to the deployment running on
hostname-a.com
.
Note
You cannot connect to a replica set via an SSH tunnel. VS Code Extension cannot establish a connection to multiple servers across the same SSH tunnel.
Optional: Specify additional options in the Advanced tab
You can select the Read Preference, which specifies how VS Code Extension directs read operations:
Read Preference Mode | Description |
---|---|
Primary | Default mode. All operations read from the current replica set
primary. |
Primary Preferred | In most situations, operations read from the primary but if it
is unavailable, operations read from secondary members. |
Secondary | All operations read from the secondary members of the replica
set. |
Secondary Preferred | In most situations, operations read from secondary members but
if no secondary members are available, operations read from
the primary. |
Nearest | Operations read from member of the replica set with the least
network latency, irrespective of the member's type. |
If omitted, defaults to Primary. To learn more about read preferences, see Read Preference.
You can specify additional MongoDB connection behavior with the following options:
Field | Description |
---|---|
Replica Set Name | (Optional) Name of replica set. |
Default Authentication Database | (Optional) Authentication database used when authSource is not specified.
For more information, see Authentication Options. |
URI Options | Additional options to customize your connection. You
specify these options as key-value pairs, and Visual Studio Code
automatically adds the key-value pairs to the connection string.
For more information, see Connection String Options. |
Connect to Atlas Stream Processing
New in version 1.50.
You can use VS Code Extension to connect to Atlas Stream Processing by providing a Stream Processing Interface (SPI) connection string.
For details on how to configure Atlas Stream Processing, see Manage Stream Processing Instances.
Paste in an SPI connection string
To obtain an SPI connection string login to your Atlas account. Click Stream Processing from the left-hand navigation and then select a Stream Processing Instance. Click Connect and choose MongoDB for VSCode from the Choose a Connection Method page of the connect dialog.
Tip
For full details on using and configuring Atlas Stream Processing, see Atlas Stream Processing Overview.
The following code block is an example of SPI connection string:
mongodb://user1:password1@atlas-stream-xxxxxxxxxxxxxxxxxxxxxxxx-yyyyy.virginia-usa.a.query.mongodb.net/?authSource=admin&readPreference=primary&ssl=true&directConnection=true
Once you are connected, the stream connection displays under the Connections pane:
Open a new VS Code Extension playground
After successfully connecting to your Atlas Stream, click Create New Playground on the Playgrounds pane. A stream processing playground template displays with pre-populated code that allows you to list stream connections and process stream data:
Activate a Connection
You can connect VS Code Extension to only one deployment at a time. To change the active connection to a different deployment, or to connect to a deployment from which you were disconnected:
Launch MongoDB Shell
You can connect the MongoDB Shell or legacy
mongo
shell to your active deployment.
Considerations
The shell that VS Code Extension uses to connect to your deployment is determined by the Shell setting in your extension settings. You can choose either the MongoDB Shell or the legacy
mongo
shell.The path to your selected shell must exist in your system's
PATH
. If it does not exist in yourPATH
, the operation errors.
Procedure
To connect the shell to your active deployment:
In the VS Code Extension Connections list, right-click your active deployment.
Select Launch MongoDB Shell.
VS Code Extension opens the Terminal window in VS Code and launches the shell connected to your selected deployment.
Edit a Connection
Copy a Connection
You can copy a connection string from an existing Visual Studio Code connection.
Rename a Connection
To rename a connection to a deployment in VS Code Extension:
Disconnect from a Deployment
VS Code Extension provides two methods to disconnect from a deployment. You can:
Disconnect with the Command Palette.
Disconnect from the MongoDB view in the Activity Bar.
Disconnecting from a MongoDB instance closes the VS Code Extension connection to the active instance. You must reconnect to interact with data in your deployment again.
Remove a Connection
VS Code Extension provides two methods to remove a connection to a deployment from Visual Studio Code. You can:
Remove a connection from the MongoDB view in the Activity Bar.
Remove a connection with the Command Palette.
Important
Removing a connection from Visual Studio Code removes it both from the current workspace and from Visual Studio Code globally.
