supersimple-db-connector
Connect Claude to any PostgreSQL, MySQL, or SQLite database. Query, inspect, and write data using natural language — no SQL knowledge required.
Overview
SuperSimple DB Connector lets Claude connect directly to PostgreSQL, MySQL, or SQLite databases via a simple DATABASE_URL environment variable. Developers and teams can list tables, inspect schemas, run SELECT queries, and perform INSERT, UPDATE, or DELETE operations using natural language—no SQL required. It integrates with Claude Desktop or any MCP-compatible AI client, with every action audit-logged for traceability.
Key Capabilities
- list_tables: Instantly lists all tables in your database.
- describe_table: Shows column names, data types, and constraints for any table.
- query_data: Executes SELECT queries with automatic pagination; blocks forbidden tables via AST-level validation.
- write_data: Runs INSERT, UPDATE, and DELETE safely, enforcing WHERE clauses on modifications to prevent data loss.
Queries are parsed and validated before execution, blocking sensitive tables (e.g., those with passwords, salaries, or secrets) beyond simple regex checks.
Use Cases
Data analysts can ask Claude to describe a sales table's schema, then query paginated results for Q3 revenue by region. Developers prototype apps by having Claude insert test records into a staging database or update user profiles with natural language conditions like "set status to active where last_login > 30 days ago." Teams review audit logs to track all AI-driven data changes in production environments.
Who This Is For
Developers integrating AI into data workflows without SQL overhead. Data analysts exploring or modifying datasets conversationally. Teams managing secure, logged access to relational databases for AI-assisted tasks.
