Built-In Roles and Privileges

The available Atlas built-in roles and specific privileges support a subset of MongoDB commands. See Unsupported Commands in M10+ Clusters for more information.

Built-in Roles

The following table describes the Atlas built-in roles and the MongoDB Roles they represent. Refer to Built-In Roles for a full description of the privilege actions that each role includes.

Note

Protected MongoDB Database Namespaces

The following databases are read-only for all users, including those with the atlasAdmin or clusterMonitor role.

local
config

We discourage writing to the admin database. Atlas manages multiple collections in the admin database, and these collections are read-only for all users.

atlasAdmin has the update privilege on the config.settings collection to manage the balancer.

It inherits the following privilege actions:

The autoCompact privilege action is specific to Atlas and allows database users with the atlasAdmin role to enable or disable background compaction. You can also create a custom database user with the autoCompact privilege enabled.
