Review Comment:
   **Suggestion:** This parsing path still throws on malformed `json_metadata`, 
so dashboards with invalid JSON will fail native-filter updates at write time 
even though the MCP tool now handles malformed metadata defensively during 
read/validation. Wrap this parse in exception handling and fall back to `{}` to 
avoid runtime write failures on legacy/corrupt rows. [possible bug]

   - ❌ MCP manage_native_filters tool crashes on corrupt metadata.
   - ⚠️ Native filter updates fail on dashboards with bad json_metadata.
   ```
   </details>
   <details>
   <summary><b>Steps of Reproduction ✅ </b></summary>
   
   ```mdx
   1. Ensure there is a dashboard row whose `json_metadata` column contains 
invalid JSON (for
   example, via a manual DB update) for an existing dashboard id; this field is 
later
   consumed without validation by `DashboardDAO.update_native_filters_config` in
   `superset/daos/dashboard.py:425-439` (verified via Read on that file).
   
   2. Call the MCP tool `manage_native_filters` with `dashboard_id` set to that 
dashboard, so
   that the tool reaches the write path; `manage_native_filters` in
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:19-88` builds 
a payload and
   then invokes `UpdateDashboardNativeFiltersCommand(request.dashboard_id, 
payload).run()` at
   lines 66-69 (Read output).
   
   3. In `UpdateDashboardNativeFiltersCommand.run` (see
   `superset/commands/dashboard/update.py:255-259` from Grep), the command calls
   `DashboardDAO.update_native_filters_config(self._model, self._properties)`, 
sending the
   MCP payload and the loaded dashboard model into the DAO layer.
   
   4. Inside `DashboardDAO.update_native_filters_config` at
   `superset/daos/dashboard.py:434-439`, the code executes `_parsed =
   json.loads(dashboard.json_metadata or "{}")` without a try/except; because
   `dashboard.json_metadata` is malformed JSON, `json.loads` raises 
`json.JSONDecodeError`,
   which is not handled by the DAO or by `UpdateDashboardNativeFiltersCommand`, 
and the outer
   `manage_native_filters` handler only logs and re-raises unexpected 
exceptions at
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:123-129`, 
resulting in an
   unhandled error for the caller when attempting to update native filters on 
that dashboard.

Review Comment:
   **Suggestion:** The dataset/column validator leaks schema details by 
returning all column names for any dataset ID, and it does so without an 
explicit dataset-access check. This enables metadata enumeration through error 
messages; return a generic validation error (or enforce datasource permission 
first) instead of exposing full column lists. [security]
   
   <details>
   <summary><b>Severity Level:</b> Major ⚠️</summary>
   
   ```mdx
   - ⚠️ Dataset existence discoverable through manage_native_filters errors.
   - ⚠️ Dataset column names exposed to potentially unauthorized MCP callers.
   ```
   </details>
   <details>
   <summary><b>Steps of Reproduction ✅ </b></summary>
   
   ```mdx
   1. Using the MCP server, a user who can invoke `manage_native_filters` but 
does not
   necessarily have access to all datasets prepares a request that adds or 
updates a
   `filter_select` filter targeting a dataset id they want to probe. The 
request uses that
   `dataset_id` and a bogus `column` name. New filters flow into 
`_build_new_filter_config`
   at `superset/mcp_service/dashboard/tool/manage_native_filters.py:47-78`, 
which calls
   `_validate_dataset_column(spec.dataset_id, spec.column)` for 
`FilterSelectSpec` instances.
   
   2. `_validate_dataset_column` is implemented at
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:86-101` and is 
invoked both
   from `_build_new_filter_config` (line 56) and from `_merge_target` during 
updates (line
   212). This helper calls `DatasetDAO.find_by_id(dataset_id)` without any 
dataset-level
   permission enforcement and, if a dataset object is returned, immediately 
iterates its
   `columns` relationship.
   
   3. When the dataset exists but the requested column name is invalid,
   `_validate_dataset_column` computes `column_names = [c.column_name for c in
   dataset.columns]` and checks `if column not in column_names:`; it then raises
   `_FilterValidationError` with an error string that includes `"Column 
'{column}' not found
   in dataset {dataset_id}. Available columns: {', 
'.join(sorted(column_names))}."`, thereby
   embedding the full list of column names for that dataset into the exception 
message.
   
   4. Back in `manage_native_filters`, this `_FilterValidationError` is caught 
at
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:56-64`, and 
the function
   returns `ManageNativeFiltersResponse(dashboard_id=request.dashboard_id, 
error=str(exc))`
   to the caller. As a result, a caller who can reach the MCP tool but lacks any
   dataset-level authorization can iteratively choose dataset ids and invalid 
column names,
   observe whether the error changes from "Dataset with ID X not found" to 
"Available
   columns: ...", and thereby confirm dataset existence and enumerate all 
column names for
   datasets that should otherwise be opaque.

Review Comment:
   **Suggestion:** The tool reads `dashboard.json_metadata` and 
`dashboard.slices` and runs detailed validation before ownership is enforced by 
the command layer. This lets non-owners trigger validation errors that reveal 
internal dashboard details (existing filter IDs, chart IDs, etc.) instead of 
getting a straight permission-denied response. Perform an ownership check 
immediately after loading the dashboard and before building payload/validation 
output. [security]

   ```
   </details>
   <details>
   <summary><b>Steps of Reproduction ✅ </b></summary>
   
   ```mdx
   1. Start the MCP server so the `manage_native_filters` tool is available; 
the tool is
   defined in 
`superset/mcp_service/dashboard/tool/manage_native_filters.py:19-88` and
   registered via `superset/mcp_service/dashboard/tool/__init__.py` (per code 
graph context).
   Assume a user who can call MCP tools and has the global Dashboard write 
permission but is
   not an owner of a specific dashboard id D (ownership enforcement happens in 
the dashboard
   command layer).
   
   2. That user calls the MCP tool `manage_native_filters` with 
`dashboard_id=D` and an
   intentionally invalid request (for example, a `remove` list containing 
filter ids that are
   not on the dashboard, or `scope_chart_ids` including invalid chart ids) so 
that validation
   will fail. In the function body at
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:42-55`, the 
code enters the
   `"mcp.manage_native_filters.validation"` log context, loads the dashboard 
via `dashboard =
   DashboardDAO.find_by_id(request.dashboard_id)`, and if found, immediately 
computes
   `current_config = _current_native_filter_config(dashboard)` and 
`dashboard_chart_ids =
   [slc.id for slc in dashboard.slices]` before any ownership check.
   
   3. `_current_native_filter_config` at
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:284-303` parses
   `dashboard.json_metadata`, extracts `native_filter_configuration`, and 
returns a list of
   filter config dicts; then `_build_native_filters_payload(request, 
current_config,
   dashboard_chart_ids)` is invoked at lines 56-59 to validate the 
user-supplied operations
   against existing filter ids and chart ids. Inside 
`_build_native_filters_payload` (lines
   305-385), the function constructs `current_by_id` from the existing filter 
configs and
   uses `dashboard_chart_ids` to validate removals, updates, and scopes.
   
   4. Because the request is invalid, `_build_native_filters_payload` raises
   `_FilterValidationError` with messages that include internal details such as 
existing
   filter ids (`sorted(current_by_id)` when an update or remove target is 
unknown) and chart
   ids (`sorted(dashboard_chart_ids)` when `scope_chart_ids` include unknown 
ids). This
   exception is caught in `manage_native_filters` at
   `superset/mcp_service/dashboard/tool/manage_native_filters.py:56-64`, where 
the function
   returns `ManageNativeFiltersResponse(dashboard_id=request.dashboard_id, 
error=str(exc))`
   to the caller. Since this all happens before the call to
   `UpdateDashboardNativeFiltersCommand` at lines 66-69, any 
`DashboardForbiddenError` raised
   by the command for non-owners (caught at lines 97-106) is never triggered, 
so a non-owner
   with tool access can repeatedly probe dashboard id D and infer its native 
filter ids and
   chart ids from the validation error strings, instead of receiving a uniform
   permission-denied response.
   ```
