NLP Database

About

NLP Database acts as a secure, read-only bridge, allowing AI agents to intuitively explore SQL database schemas and query data using natural language via the Model Context Protocol (MCP). It ensures safe interactions with strict query validation, automatic result limiting, and broad compatibility with major SQL databases like PostgreSQL, MySQL, SQL Server, and SQLite, all while optimizing for agent performance with descriptive errors and schema caching.

Key Features

• Agent-optimized with descriptive errors for LLM self-correction
• 5-minute schema caching to reduce database overhead
• Native support for PostgreSQL, MySQL, SQL Server, and SQLite
• Strict read-only security with regex validation for SELECT and WITH statements
• Automatic query guardrails with 'LIMIT 500' to prevent system overload
• 0 GitHub stars

Use Cases

• Enabling LLMs to answer user questions about data by inspecting schemas and executing queries
• Integrating database querying capabilities into various LLM clients like Claude, Gemini, and OpenCode
• Providing AI agents with secure, natural language access to transactional or analytical databases
