# Unsupported Commands in Atlas

## Unsupported Commands in M0 and Atlas Flex Clusters

Atlas Free clusters and Flex clusters don't support all functionality available to other clusters. To learn more about `M0` cluster limits, see [Atlas Free Cluster Limits](https://www.mongodb.com/docs/atlas/reference/free-shared-limitations.md#std-label-atlas-free-tier). To learn more about Flex cluster limits, see [Atlas Flex Limitations.](https://www.mongodb.com/docs/atlas/reference/flex-limitations.md#std-label-flex-cluster-limitations)

**Note:**

If you use an unsupported command or invalid syntax, Atlas returns the following error message:

```shell
 <$command> is not allowed or the syntax is incorrect,
 see the Atlas documentation for more information.
```

To learn more about valid syntax, see [Database Commands](https://www.mongodb.com/docs/manual/reference/command/)

### Limited Commands

You can run the following commands with limits in Free clusters and Flex clusters:

| Command | Limit |

### Unsupported Command Line Options

Free clusters and Flex clusters don't support the following command line tool options:

| Command Line Tool | Unsupported Options |
| --- | --- |
| [`mongorestore`](https://www.mongodb.com/docs/database-tools/mongorestore.md#mongodb-binary-bin.mongorestore) | [--restoreDbUsersAndRoles](https://www.mongodb.com/docs/database-tools/mongorestore/#std-option-mongorestore.--restoreDbUsersAndRoles); [--oplogReplay](https://www.mongodb.com/docs/database-tools/mongorestore/#std-option-mongorestore.--oplogReplay); [--preserveUUID](https://www.mongodb.com/docs/database-tools/mongorestore/#std-option-mongorestore.--preserveUUID) |
| [`mongodump`](https://www.mongodb.com/docs/database-tools/mongodump.md#mongodb-binary-bin.mongodump) | [--dumpDbUsersAndRoles](https://www.mongodb.com/docs/database-tools/mongodump/#std-option-mongodump.--dumpDbUsersAndRoles); [--oplog](https://www.mongodb.com/docs/database-tools/mongodump/#std-option-mongodump.--oplog) |

For more information, see [M0 Cluster Limits.](https://www.mongodb.com/docs/atlas/reference/free-shared-limitations.md#std-label-atlas-free-tier)

## Unsupported Commands in M10+ Clusters

Atlas requires clients to authenticate to access an Atlas cluster. Atlas provides a curated list of [Database User Privileges](https://www.mongodb.com/docs/manual/reference/built-in-roles.md#std-label-atlas-user-privileges). These privileges provide access to a subset of MongoDB commands.

### Limited Commands

Atlas limits the [`db.killOp()`](https://www.mongodb.com/docs/manual/reference/method/db.killOp.md#mongodb-method-db.killOp) method to the MongoDB user who ran the operation.

Atlas supports the following sharding command on only `M30+` sharded clusters:

| Command | Shell Method | Privilege Action |
| --- | --- | --- |
| [abortRewriteCollection](https://www.mongodb.com/docs/upcoming/reference/command/abortRewriteCollection/) |  | [rewriteCollection](https://www.mongodb.com/docs/upcoming/reference/privilege-actions/#mongodb-authaction-rewriteCollection) |

The following table lists the most common commands and shell methods that database user privileges do not support. To ensure cluster stability and performance, Atlas subsumes or restricts the functionality that these commands provide.
