SQLclMCP: A Rigorous Evaluation Framework for NL2SQL on Oracle Database
This article introduces SQLclMCP, an open-source framework designed to evaluate the performance of Large Language Models (LLMs) in converting natural language to SQL (NL2SQL) specifically for Oracle Database. Addressing critical concerns regarding correctness, executability, and efficiency in production environments, the framework utilizes the Model Context Protocol (MCP) to standardize evaluations through a single HTTP API. This approach allows developers to swap models, prompts, or server implementations while maintaining consistent testing conditions. The system benchmarks LLM-generated SQL against human-written baselines using a 500-question TPC-H dataset. By ensuring that query results match logical expectations, execute without errors, and demonstrate reasonable latency via Oracle EXPLAIN PLAN, SQLclMCP provides a repeatable pipeline for improving prompt engineering and comparing model capabilities. The framework also addresses specific dialect nuances, such as differences between Oracle and MySQL syntax, helping enterprises ship NL2SQL applications with greater confidence and reliability.
