Bonnard

Agent-native analytics. One schema, many surfaces.

BI tools serve one UI. Bonnard serves everything. Agents over MCP, apps over SDK, dashboards in markdown, internal tools via REST. One set of metric definitions, every consumer gets the same governed answer.

Traditional semantic layers were built for dashboards and retrofitted for AI. Agents get different answers than dashboards, metrics drift across tools, and every new surface means another integration. Bonnard was built agent-native from day one. MCP is a core feature, not a plugin. One CLI, one schema, every consumer gets the same governed answer.

No install required. Run directly with npx:

bon init # Scaffold project + agent configs bon datasource add # Connect your warehouse bon validate # Check your models locally bon login # Authenticate bon deploy -m "initial deploy" # Ship it

Your semantic layer is now live. Agents, dashboards, and the SDK all query the same governed metrics.

No warehouse yet? Start exploring with a full retail demo dataset:

Warehouses:Snowflake (including Snowpark), Google BigQuery, Databricks (SQL warehouses and Unity Catalog), PostgreSQL (including Supabase, Neon, and RDS), Amazon Redshift, DuckDB (including MotherDuck)

Data tools:dbt (model and profile import), Dagster, Prefect, Airflow (orchestration), Looker, Cube, Evidence (existing BI layers), SQLMesh, Soda, Great Expectations (data quality)

Bonnard auto-detects your warehouses and data tools. Point it at your project and it discovers schemas, tables, and relationships.

Contributions are welcome. If you find a bug or have an idea, open an issue or submit a pull request.
