Zero hallucinations in the AI you already use. Every number traces to a Data Mart.

When the CEO asks Claude or ChatGPT about revenue, an assistant reading raw tables guesses the joins, and the wrong number lands in the meeting with your name on it. OWOX MCP answers from the Data Marts you published instead.

• The assistant never writes SQL: it picks fields and filters, OWOX builds the query over your joins, and Run History keeps the SQL it ran.
• Only published Data Marts are reachable, each member sees what their role allows, and the assistant cannot add a join you did not define.
• The answer reads the same published Data Mart as your Google Sheets report and Data Studio dashboard; ask for the report in Google Sheets, open the link and keep working there in the OWOX Extension.
• Nothing to switch on: publish a Data Mart, and the assistant can find it.

The CMO asks why the dashboard app and the Google Sheets report disagree on revenue: the app reads the warehouse with its own copy of your SQL. The Data API builds, describes, joins and publishes Data Marts from code, and apps and AI agents read those published Data Marts, with a key that acts as you.

• Every pull, an AI agent's included, is a run in Run History with the request that made it, so a number from a script can be reproduced.
• Apps and agents read only published Data Marts with the joins you declared, the same definition your reports use; a key carries your access, nothing wider.
• Your AI agent or one script creates the drafts, describes every column, declares the joins and publishes; ask again, or rerun the script, after an upstream rename.
