DuckDB

pip install "dataveil[duckdb]"

import duckdb
from dataveil.adapters.duckdb import DuckDBAdapter

adapter = DuckDBAdapter(duckdb.connect("warehouse.duckdb"))

The reference adapter, and the one dataveil's own test suite runs against. It supports all eight operations. It registers the Luhn and IBAN checksum functions as DuckDB functions, so every classifier works, and the person-name function when the ner extra and en_core_web_sm are installed. Pass register_ner_function=False to skip the name model.

With the MCP server: DATAVEIL_ADAPTER=duckdb and DATAVEIL_DUCKDB_PATH, or [adapter] kind = "duckdb" and duckdb_path.
