Neocarta Open Source: Solving Upstream Pain Points for Text-to-SQL Agents
JeremyCMorgan · x · 2026-08-01
Text-to-SQL agents often fail before SQL generation even starts, primarily because they don't know which table means what or how tables relate.
To solve this upstream pain point, Neo4j Labs has introduced the open-source library Neocarta. The tool builds a graph from BigQuery metadata, business terms, and observed query logs, and then serves this semantic layer to agents over MCP (Model Context Protocol), helping AI better understand and navigate underlying data structures.
