Lucen
Claude connectorCommunityAsk questions, rank campaigns and draft dashboards from your organization's clean marketing data in BigQuery
Lucen is a managed data pipeline built and run by Blumie. It loads your ad platforms, store, CRM and analytics into a BigQuery warehouse (your own Google Cloud project, or one Blumie runs for you) and models them into clean, analysis-ready tables. The Lucen MCP server gives Claude governed access to that data.
With Lucen, Claude can:
- Answer questions about spend, ROAS, conversions and revenue with read-only queries on your organization's warehouse.
- Reuse the saved, validated queries in your team's query library.
- Rank campaigns and ads fairly, even when they ran for different lengths of time.
- Explain how a metric is calculated by reading your pipeline's transformation code.
- Check how fresh each table is before trusting a number.
- Draft Blocks dashboard pages you review and publish in the Lucen portal.
Security and permissions:
- Sign-in uses OAuth 2.1 with PKCE, and you choose which organizations each connection can use.
- Read access comes with every connection. Write access (saving queries, writing dashboard drafts) is a separate permission, and Claude asks before either write tool runs.
- Queries must be a single read-only SELECT, pass a BigQuery dry-run cost check, and return at most 1,000 rows.
- Organization membership is checked on every call, so removing someone ends their access right away.
- The connector does not store query results, and nothing is published without a person's click.
