About

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.
