# ToolFront

> Use this tool when you need to manage and query multiple databases through a unified interface, solving problems of data siloing and complexity in heterogeneous environments. ToolFront provides inputs for SQL queries and database connections, and outputs serialized results and table schema information, making it ideal for exploring and analyzing data across various database types. It is particularly useful in contexts where AI assistants require database-agnostic access to discover, inspect, and query data from diverse sources.

## Description

ToolFront is a lightweight MCP server for database management and querying built by Kruskal Labs that provides unified access to multiple database types including PostgreSQL, MySQL, SQLite, DuckDB, BigQuery, and Snowflake through a single interface. The server offers tools for discovering datasources, inspecting table schemas, sampling data, executing read-only SQL queries with automatic result serialization, and scanning tables using multiple pattern matching algorithms (regex, TF-IDF, Jaro-Winkler similarity). It includes intelligent async/sync fallback mechanisms for database connections, optional integration with Kruskal's API for query learning and semantic search, and Docker deployment support, making it valuable for AI assistants that need to explore and analyze data across heterogeneous database environments without requiring database-specific knowledge.
