About Exmergo Dex

Exmergo Dex is an agent-native analytics engineering toolkit designed to integrate with coding agents such as Claude Code, Cursor, and others. It connects to a data warehouse and a dbt project, learning the schema landscape to author transformations, detect schema drift, and suggest fixes. The tool enforces cost guards to prevent excessive warehouse scanning or token consumption, addressing the financial risks of unchecked agent activity. It profiles columns, infers relationships, and builds a local draft map of tables while automatically flagging PII. Dex supports exploration, transformation, and maintenance workflows with dependency-aware dbt SQL model generation, schema tests, and MetricFlow YAML authoring. The system validates changes against development targets before execution and provides reconciling edits for schema and volume drift issues. It is built for teams managing both warehouse consumption and AI token costs, offering open-source access under the Apache 2.0 license.
