AI Agents: Semantic Layer Beats Text-to-SQL for Data Warehouse Trust

This article proposes a more robust method for connecting AI agents to data warehouses, moving beyond traditional text-to-SQL approaches. The author advocates for defining business metrics in a semantic layer and exposing them via the Model Context Protocol (MCP). This ensures consistency and trust by providing agents with governed metric definitions rather than raw table access, which can lead to hallucinations and inconsistencies. The proposed architecture allows for easier infrastructure changes and provides essential features like access control and audit trails. AI

IMPACT This approach enhances trust and consistency when AI agents access data, potentially improving enterprise AI adoption.

RANK_REASON Article describes a technical approach and tooling for integrating AI agents with data warehouses.
