Show HN: Nexus, ask AI about sensitive spreadsheets locally

Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

Nexus is a local-first MCP server that exposes spreadsheets and databases as semantic tools for AI agents like Claude Code, allowing querying and manipulation without data leaving the machine. Its non-destructive derivation layer (views, branches, snapshots) and support for multiple tabular formats address a real gap in private AI-data interaction, though the project is still early-stage with few stars.

Target audience: backend devs, data engineers, ai-ml engineers
