Polyglot DB

概要

Modern applications often leverage a diverse ecosystem of databases, leading to the tedious task of switching between various CLIs, APIs, and query languages. Polyglot DB eliminates this complexity by offering a single, unified MCP server that allows AI agents, such as Claude, and other MCP clients to interact with 16 distinct database types—including PostgreSQL, MongoDB, Neo4j, Elasticsearch, Redis, and vector databases like Qdrant—through natural language queries. Built with a ReScript core and running on Deno, it streamlines development and operations by enabling seamless cross-database data access and correlation.

主な機能

• Enables natural language querying of databases via AI agents like Claude and other MCP clients.
• 1 GitHub stars
• Developed with ReScript for type safety and efficient execution on the Deno runtime.
• Unified interface for interacting with 16 diverse database types (SQL, NoSQL, Graph, Cache, Search, Vector, Time Series, Analytics, Specialized).
• Flexible deployment options including direct execution, containerization (Docker, Podman), and serverless (Deno Deploy).
• Supports complex cross-database operations and data pipelines (e.g., PostgreSQL query results cached in Redis).

ユースケース

• Querying relational data in PostgreSQL and caching specific results in Redis with natural language commands.
• Searching for documents in Elasticsearch and correlating findings with audit logs stored in MongoDB.
• Storing AI embeddings in vector databases like Qdrant and linking them to knowledge graphs in Neo4j.
• Consolidating database management for polyglot applications through a single MCP server.
