Who it is for
Analytics teams that maintain a governed semantic layer and want business questions answered against it.
Overview
What OWOX Data Marts does
OWOX Data Marts connects ChatGPT or Codex to an analytics layer that data analysts have defined in advance. Each data mart fixes its own metrics, dimensions, and join logic, and it sits on top of the company's existing warehouse, whether that is BigQuery, Snowflake, Databricks, Redshift, or Athena.
From the conversation, a natural language search locates the right mart, its fields can be inspected, and the query runs against governed data. Totals are computed server side from the definitions the analyst wrote rather than assembled out of raw tables. Recurring report schedules can also be managed. The data stays in the warehouse and OWOX does not retain it.
What stands out
Answers come from analyst-defined metrics and joins instead of improvised queries over raw tables, and nothing is copied out of the warehouse.
Availability
Where OWOX Data Marts is listed
OWOX ships this on both marketplaces: OWOX Data Marts is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
OWOX Data Marts publishes 18 tools to Claude, deeper than 65.6% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Data & Analytics publishes 12, so this one runs 6 tools above its bucket's median and ranks 54th of 198 by tool count.
It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.
OWOX Data Marts publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

OWOX Data Marts is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
How OWOX describes it
OWOX Data Marts connects Claude to your company's governed analytics layer. Data Analysts define trusted Data Marts — metrics, dimensions, and join logic — on top of your own warehouse (BigQuery, Snowflake, Databricks, Redshift, Athena). From Claude you can: • Discover the right data mart for any question with natural-language semantic search • Inspect a mart's fields, metrics, and joinable dimensions • Query governed data and get answers with server-side totals — computed from analyst-defined metrics and joins, never guessed from raw tables • See available destinations and manage recurring report run schedules Every answer comes from analyst-approved definitions, so metrics stay consistent and joins are never hallucinated. Your data stays in your own warehouse — OWOX connects to it but never retains it.
