Polyglot DB

关于

Polyglot DB eliminates the complexity of managing multiple databases by providing a single, unified MCP server. Modern applications often leverage various database types—relational for transactions, Redis for caching, Elasticsearch for search, and vector databases for AI. This tool allows you to query PostgreSQL, MongoDB, Neo4j, Elasticsearch, Redis, and 15 more databases directly through natural language, enabling seamless cross-database operations and significantly reducing context switching for developers and AI agents like Claude.

主要功能

• Support for cross-database operations and pipelines (e.g., query PostgreSQL and cache in Redis)
• Flexible deployment options including direct, containerized (Docker, Podman, Nerdctl), and serverless (Deno Deploy)
• Natural language querying capabilities via MCP clients for simplified database interaction
• Built with ReScript for type safety and compiled to run efficiently on Deno
• Unified interface for 20 diverse databases (SQL, NoSQL, Graph, Cache, Search, Vector, Time Series, Analytics)
• 1 GitHub stars

使用案例

• Searching Elasticsearch for critical errors and correlating them with MongoDB audit logs
• Querying users from PostgreSQL and caching the results in Redis for faster access
• Storing AI embeddings in Qdrant and linking them to a Neo4j knowledge graph for rich context
