Query
Which customers ordered less this month?
ERP analytics without the warehouse tax
You do not need a six-figure data stack to ask your ERP a question.
Cetari connects to legacy ERP systems, transforms the data into open Parquet, and exposes it through DuckDB, ODBC/JDBC, and MCP — so people, BI tools, and AI agents can all query the same governed data layer.
The modern data stack is overkill for most ERP reporting problems.
Most companies are not trying to build a data platform for its own sake. They are trying to answer operational questions trapped inside the ERP.
Query
What inventory is aging past 60 days?
Query
Which vendors are late most often?
Query
What did we ship by region last quarter?
Query
What changed in margin by product line?
One managed query layer for humans, dashboards, and AI agents.
Cetari turns legacy ERP data into a clean, queryable layer. Plain-English answers are one surface. The core product is the governed infrastructure underneath.
A Natural-language surface
Ask in plain English
Operations users ask questions and get charts, tables, or numbers without waiting for a new report cycle.
B ODBC/JDBC endpoints
Connect BI tools
Power BI, Tableau, Looker, Hex, Excel, and similar tools connect through ODBC/JDBC.
C DuckDB SQL access
Query with SQL
Analysts and technical users can query modeled ERP data through DuckDB.
D MCP server
Connect AI tools through MCP
AI assistants and agent workflows query governed ERP data instead of relying on stale spreadsheets, unsafe direct ERP access, screenshots, or one-off exports.
Give AI agents a governed path to ERP data.
Cetari’s MCP server lets AI tools query modeled ERP data through a controlled layer — without direct production ERP access, spreadsheet uploads, or hallucinated business metrics.
Why it matters
AI is only useful when it can reach the right operational data.
- No raw production ERP access
- No stale spreadsheet uploads
- No one-off analyst extracts
- No hallucinated business metrics
- One governed query layer over modeled ERP data
Open data. Fast queries. No warehouse tax.
Cetari extracts ERP data, models it into open Parquet files, stores it in single-tenant cloud storage, and exposes it through DuckDB, ODBC/JDBC, and MCP.

Cetari is not trying to replace every enterprise data platform for every use case. It is built for ERP analytics and operational reporting where the usual stack is more machinery than the problem requires.

High recurring platform cost
Simpler managed pricing
Built for the people stuck waiting on reports.
Operations, finance, IT, and analysts all work from the same governed ERP data layer instead of passing extracts, screenshots, and report tickets around the business.
For Operations
Ask what is happening in inventory, fulfillment, purchasing, shipping, and customer activity.
For Finance
Get faster visibility into revenue, margin, order trends, and operational performance.
For IT
Modernize ERP reporting without stitching together a fragile stack of vendors.
For Analysts
Use the same clean datasets in Power BI, Tableau, Looker, Hex, Excel, SQL, or AI workflows.
