spiculedata/saiku

Open-source semantic layer: one cube for Excel (MDX/XMLA), dashboards, and AI agents (MCP). Mondrian + Apache Calcite.

About the project

Saiku is an open-source semantic layer that represents data as analytical cubes for browser exploration, SQL queries, dashboards, and AI-agent access. It is for analysts and applications that need to query structured business data through Mondrian, Apache Calcite, REST, or MCP. The catalogue instruction helps agents work with Saiku.

This repository also configures its own agents. See what saiku tells them →
