When Superset is deployed as a subdirectory (SUPERSET_APP_ROOT), export
URLs were getting the app root applied twice. SupersetClient.postForm()
adds the appRoot internally via getUrl(), so callers must not pre-apply
ensureAppRoot() before passing an endpoint to any SupersetClient method.
Fix:
- exportChart: build URL without appRoot; apply ensureAppRoot only for
the streaming path (native fetch), leave raw for postForm path
- DrillDetailPane: remove ensureAppRoot() before SupersetClient.postForm()
- chartAction: remove ensureAppRoot() before SupersetClient.postForm()
- Add getExploreUrl includeAppRoot param to support building unprefixed
legacy API URLs for the non-streaming fallback
- Add regression test: postForm must receive unprefixed URL even when
SUPERSET_APP_ROOT is configured

When the feature flag is enabled, these permissions are enforced on both the frontend (disabled buttons with tooltips) and backend (403 responses from API endpoints). When disabled, legacy `can_csv` behavior is preserved.
**Migration behavior:** All three new permissions are granted to every role that currently has `can_csv`, preserving existing access. Admins can then selectively revoke individual export permissions from specific roles as needed.
### Deck.gl MapBox viewport and opacity controls are functional
The Deck.gl MapBox chart's **Opacity**, **Default longitude**, **Default latitude**, and **Zoom** controls were previously non-functional — changing them had no effect on the rendered map. These controls are now wired up correctly.

# AWS IAM Authentication for AWS Databases
Superset supports IAM-based authentication for **Amazon Aurora** (PostgreSQL and MySQL) and **Amazon Redshift**. IAM auth eliminates the need for database passwords — Superset generates a short-lived auth token using temporary AWS credentials instead.
Cross-account IAM role assumption via STS `AssumeRole` is supported, allowing a Superset deployment in one AWS account to connect to databases in a different account.
## Prerequisites
- Enable the `AWS_DATABASE_IAM_AUTH` feature flag in `superset_config.py`. IAM authentication is gated behind this flag; if it is disabled, connections using `aws_iam` fail with *"AWS IAM database authentication is not enabled."*
```python
FEATURE_FLAGS = {
"AWS_DATABASE_IAM_AUTH": True,
}
```
- `boto3` must be installed in your Superset environment:
```bash
pip install boto3
```
- The Superset server's IAM role (or static credentials) must have permission to call `sts:AssumeRole` (for cross-account) or the same-account permissions for the target service:
- **Redshift Serverless**: `redshift-serverless:GetCredentials` and `redshift-serverless:GetWorkgroup`
- SSL must be enabled on the Aurora / Redshift endpoint (required for IAM token auth).
## Configuration
IAM authentication is configured via the **encrypted_extra** field of the database connection. Access this field in the **Advanced** → **Security** section of the database connection form, under **Secure Extra**.
**3. Configure the database connection in Superset** using the `role_arn` and `external_id` from the trust policy (as shown in the configuration example above).
## Credential Caching
STS credentials are cached in memory keyed by `(role_arn, region, external_id)` with a 10-minute TTL. This reduces the number of STS API calls when multiple queries are executed with the same connection. Tokens are refreshed automatically before expiry.
The superset cli allows you to import and export datasources from and to YAML. Datasources include
databases. The data is expected to be organized in the following hierarchy:
:::info
Superset's ZIP-based import/export also covers **dashboards**, **charts**, and **saved queries**, exercised through the UI and REST API. The [Dashboard Import Overwrite Behavior](#dashboard-import-overwrite-behavior) and [UUIDs in API Responses](#uuids-in-api-responses) sections below document the behavior shared across all asset types.

@@ -75,6 +79,29 @@ The optional username flag **-u** sets the user used for the datasource import.
When importing a dashboard ZIP with the **overwrite** option enabled, any existing charts that are part of the dashboard are **replaced** rather than duplicated. This applies to:
- Charts whose UUID matches a chart already present in the target instance
- The full chart configuration (query, visualization type, columns, metrics) is replaced by the imported version
If you import without the overwrite flag, existing charts with conflicting UUIDs are left unchanged and the import skips those objects. Use overwrite when you want to push a fully updated dashboard (including chart definitions) from a development or staging environment to production.
## UUIDs in API Responses
The REST API POST endpoints for **datasets**, **charts**, and **dashboards** include the auto-generated `uuid` field in the response body:
```json
{
"id": 42,
"uuid": "b8a8d5c3-1234-4abc-8def-0123456789ab",
...
}
```
UUIDs remain stable across import/export cycles and can be used for cross-environment workflows — for example, recording a UUID when creating a chart in development and using it to identify the matching chart after importing into production.

## Audit Events
All MCP tool calls are logged to Superset's event logger, the same system used by the web UI (viewable at **Settings → Action Log**). Each event captures:
- **User**: the resolved Superset username from the JWT or dev config
- **Timestamp**: when the operation ran
This means MCP activity is auditable alongside normal user activity. No additional configuration is required — logging is on by default whenever the event logger is enabled in your Superset deployment.
## Tool Pagination
MCP list tools (`list_datasets`, `list_charts`, `list_dashboards`, `list_databases`) use **offset pagination** via `page` (1-based) and `page_size` parameters. Responses include `page`, `page_size`, `total_count`, `total_pages`, `has_previous`, and `has_next`. To iterate through all results:
```python
# Example: fetch all charts across pages
all_charts = []
page = 1
while True:
result = mcp.list_charts(page=page, page_size=50)
all_charts.extend(result["charts"])

To strive for data consistency (regardless of the timezone of the client) the Apache Superset backend tries to ensure that any timestamp sent to the client has an explicit (or semi-explicit as in the case with [Epoch time](https://en.wikipedia.org/wiki/Unix_time) which is always in reference to UTC) timezone encoded within.

Superset provides granular, permission-based controls for data export, image export, and clipboard operations. These replace the legacy `can_csv` permission with three fine-grained permissions that can be assigned independently to roles.
## Feature Flag
Granular export controls are gated behind the `GRANULAR_EXPORT_CONTROLS` feature flag. When the flag is disabled, the legacy `can_csv` permission behavior is preserved.
| `can_export_data` | `Superset` | CSV, Excel, and JSON data exports from charts, dashboards, and SQL Lab |
| `can_export_image` | `Superset` | Screenshot (JPEG/PNG) and PDF exports from charts and dashboards |
| `can_copy_clipboard` | `Superset` | Copy-to-clipboard operations in SQL Lab and the Explore data pane |
## Default Role Assignments
The migration grants all three new permissions (`can_export_data`, `can_export_image`, `can_copy_clipboard`) to every role that currently has `can_csv`. This preserves existing behavior — no role loses access during the upgrade.
After the migration, admins can selectively revoke individual export permissions from any role to restrict access. For example, to prevent Gamma users from exporting data or images while still allowing clipboard operations, revoke `can_export_data` and `can_export_image` from the Gamma role.
## Configuration Steps
1. **Enable the feature flag** in `superset_config.py`:
```python
FEATURE_FLAGS = {
"GRANULAR_EXPORT_CONTROLS": True,
}
```
2. **Run the database migration** to register the new permissions:
```bash
superset db upgrade
```
3. **Initialize permissions** so roles are populated:
```bash
superset init
```
4. **Verify role assignments** in **Settings > List Roles**. Confirm that each role has the expected permissions from the table above.
5. **Customize as needed**: Grant or revoke individual export permissions on any role through the role editor.
## User Experience
When a user lacks a required export permission:
- **Menu items** (CSV, Excel, JSON, screenshot) appear **disabled** with an info tooltip icon explaining the restriction
- **Buttons** (SQL Lab download, clipboard copy) appear **disabled** with a tooltip on hover
- **API endpoints** return **403 Forbidden** when the corresponding permission is missing
## API Enforcement
The following API endpoints enforce granular export permissions when the feature flag is enabled:
