Secure AI-Powered SQLite Management for Business Intelligence
Automate SQLite database operations via natural language, reducing manual query time by up to 90% and enhancing data accessibility for business intelligence.
Manual SQLite database management requires technical expertise and often risks direct SQL injection. This n8n workflow provides a secure, AI-powered interface for SQLite, enabling natural language interactions while preventing raw SQL execution.

Secure AI-Powered SQLite Database Management
This n8n workflow demonstrates how to build a robust and secure SQLite database management system, powered by an AI agent. Leveraging the Model Context Protocol (MCP), it enables users to interact with a local SQLite database using natural language queries for various business intelligence and data operations, all while upholding critical security measures against direct SQL injections. Ideal for self-hosted instances, this solution transforms complex database tasks into simple conversations.
Key Features
- Secure Parameterized Queries: Safeguard your database by preventing raw SQL statements from AI agents, ensuring only validated parameters are used.
- AI Agent Integration: Connect with any MCP-compatible AI client for natural language database interactions.
- Comprehensive Database Operations: Support for listing tables, describing schemas, reading records, inserting new data, and updating existing entries.
- Customizable Workflow Tools: Define restricted schemas for tool inputs to precisely control AI agent capabilities and enforce data integrity.
- Self-Hosted Compatibility: Designed specifically for self-hosted n8n instances accessing local SQLite database files.
How It Works
The workflow is initiated by an SQLite MCP Server trigger, which exposes five distinct tools to an external AI agent. Two Code Nodes handle read-only operations like listing and describing tables directly. For write operations (insert, update, read with filters), three Tool Workflow nodes are used. These custom workflow tools trigger an internal Execute Workflow Trigger within the same workflow, passing specific operation parameters. A Switch node then routes these requests to dedicated Code Nodes responsible for constructing and executing secure, parameterized SQL statements against the SQLite database. This layered approach ensures that raw SQL never reaches the database directly from the AI agent, enhancing security and preventing SQL injection.
