masthead-data-scans

Set up a data quality scan end to end — define a metric with the user, materialize it as a BigQuery table in a masthead_dq dataset with a scheduled query that keeps it current, give Masthead read access to that dataset only, then validate and create the scan through the Masthead MCP server. Also lists, pauses, updates, and deletes existing scans. Every BigQuery change and every scan change runs only on explicit confirmation.

Compatibility

Requires the Masthead MCP server at `https://mcp.mastheadata.com/mcp` (US region) and the `bq` CLI signed in to the customer's Google Cloud project, with permission to create datasets, tables, and scheduled queries (BigQuery Data Transfer API).
