HyperDB MCP Server

HyperDB MCP Server (v0.4.0) is an MCP (Model Context Protocol) server that turns Hyper, a columnar SQL database, into an instant analytics engine for LLM workflows. It provides zero-setup SQL analytics, ingesting data from JSON, CSV, Parquet, or Arrow formats and enabling query via SQL. Built on pure-Rust HyperDB, it achieves high ingest and query throughput (22M+ rows/sec insert, 18M+ rows/sec query). The server supports persistent databases for cross-session memory, shared daemon for multiple MCP clients, read-only mode, and inline chart generation. As a pre-1.0 release (0.x), it may undergo breaking changes frequently. Release cadence is rapid with multiple versions per month. Key differentiators: optimized for AI toolchains, combines structured queryable memory with columnar analytics, and features incremental ingest via watch directories.
