spiculedata / saiku
Open-source semantic layer: one cube for Excel (MDX/XMLA), dashboards, and AI agents (MCP). Mondrian + Apache Calcite.
Why this job: works in the areas we cover, but does not say which job it does
What it does
Open-source Semantic Layer analytics for cubes — drag-and-drop in the browser, SQL through Mondrian + Calcite, and a typed REST surface so AI agents can query without ever seeing MDX.
