The SQLite MCP Server transforms SQLite into a powerful, AI-ready database engine. It combines standard relational operations with advanced analytics, text and vector search, geospatial capabilities, and intelligent workflow automation. By layering business intelligence tools, semantic resources, and guided prompts on top of SQLite, it enables both developers and AI assistants to interact with data more naturally and effectively.

By layering business intelligence tools, semantic resources, and guided prompts on top of SQLite, it enables both developers and AI assistants to interact with data more naturally and effectively. This makes it not just a database interface, but a **workflow-aware assistant** for developers and AI systems. ## Key Features * **Advanced Text Processing**: Comprehensive text analysis toolkit with 8 specialized tools: PCRE regex extraction/replacement, fuzzy matching with Levenshtein distance, phonetic matching (Soundex/Metaphone), text similarity analysis (Cosine/Jaccard), normalization operations, pattern validation, advanced multi-method search, and comprehensive text validation * **Statistical Analysis Library**: Comprehensive statistical functions for data analysis including descriptive statistics, percentile analysis, and time series analysis * **JSONB Binary Storage**: Efficient binary JSON storage for improved performance and reduced storage requirements * **Transaction Safety**: All write operations automatically wrapped in transactions with proper rollback on errors * **Foreign Key Enforcement**: Automatic enforcement of foreign key constraints across all connections * **Advanced SQL Support**: Complex queries including window functions, subqueries, and advanced filtering * **Business Intelligence**: Integrated memo resource for capturing business insights during analysis * **Enhanced Error Handling**: Detailed diagnostics for JSON-related errors with specific suggestions for fixing issues * **Multi-Level Caching**: Hierarchical caching for optimal performance * **Pattern Recognition**: Automatic optimization of frequently executed queries * **JSON Validation**: Prevents invalid JSON from being stored in the database * **WAL Mode Compatible**: Works alongside the existing Write-Ahead Logging (WAL) journal mode * **Comprehensive Schema Tools**: Enhanced tools for exploring and documenting database structure * **Database Administration Tools**: Complete suite of maintenance tools including VACUUM, ANALYZE, integrity checks, performance statistics, and index usage analysis * **Full-Text Search (FTS5)**: Comprehensive FTS5 implementation with table creation, index management, and enhanced search with BM25 ranking and snippets * **Backup/Restore Operations**: Enterprise-grade backup and restore capabilities with SQLite backup API, integrity verification, and safety confirmations * **Advanced PRAGMA Operations**: Comprehensive SQLite configuration management, performance optimization, and database introspection tools * **Virtual Table Management**: Complete virtual table lifecycle management for R-Tree spatial indexing, CSV file access, and sequence generation * **SpatiaLite Geospatial Analytics**: Enterprise-grade GIS capabilities with spatial indexing, geometric operations, and comprehensive spatial analysis * **Enhanced Virtual Tables**: Smart CSV/JSON import with automatic data type inference, nested object flattening, and schema analysis * **Semantic/Vector Search**: AI-native semantic search with embedding storage, cosine similarity, and hybrid keyword+semantic ranking * **Vector Index Optimization**: Approximate Nearest Neighbor (ANN) search with k-means clustering and spatial indexing for sub-linear O(log n) performance * **Intelligent MCP Resources**: Dynamic database meta-awareness with real-time schema, capabilities, statistics, search indexes, and performance insights * **Guided MCP Prompts**: Intelligent workflow automation with semantic query translation, table summarization, database optimization, and hybrid search recipesThe SQLite MCP Server transforms SQLite into a powerful, AI-ready database engine.
