kosminus/querywise-mcp

Overview

querywise-mcp is an open-source MCP server and CLI that enables LLMs to query databases using natural language through a business semantic layer. It combines glossary terms, metric definitions, data dictionary, knowledge base, and example queries, all grounded against the actual database schema.

Best for
Developers building natural-language data query interfaces that need business context and schema grounding

Use cases

• Integrating natural-language database queries into internal tools or chat interfaces
• Standardizing business metrics and definitions for consistent LLM-generated SQL
• Building a semantic layer that reduces ambiguity in data access for non-technical users

Use cases

• Integrating natural-language database queries into internal tools or chat interfaces
• Standardizing business metrics and definitions for consistent LLM-generated SQL
• Building a semantic layer that reduces ambiguity in data access for non-technical users

Pros

• Grounds queries in real schema and business definitions, reducing hallucination and SQL errors
• Open-source and modular, allowing customization for different databases and LLMs
• Provides a structured way to reuse example queries and domain knowledge

Cons

• Early-stage project with low community adoption, limited documentation and support
• Requires upfront effort to define and maintain the semantic layer (glossary, dictionary, examples)
• Performance and accuracy depend heavily on the underlying LLM and database complexity
