Review Comment:
   NIT — `continue` is the last statement in the loop body here; there's 
nothing after the `try/except` block within the `for item in v` loop, so this 
is a no-op. Remove it.

Review Comment:
   HIGH — `logger = logging.getLogger(__name__)` sits between the stdlib 
imports and the third-party imports. Ruff E402 fires on the `from pydantic 
import (` block at line 28. Pre-commit CI is failing on this branch because of 
this ordering.
   
   Move the logger assignment to after all imports (after the last `from 
superset.mcp_service.utils.schema_utils import ...` line).
   
   ```suggestion
   ```
   
   Delete this line here and add `logger = logging.getLogger(__name__)` after 
line 47 (after the last import).
