This June, Dewey has added improvements to how you access data and launched the MCP in the ChatGPT app store.
Get data Workflow and Customization Improvements
Users can now download exactly what they need with added text based filters and reduced customization limits on most datasets
- Filter by text columns - Search high-cardinality fields like city or company name using keyword chips. Matching is case-insensitive and finds any value containing your text.
- Row count and file size estimates - See an estimated row count and file size as you apply filters, so you can plan storage before downloading.
- Filters shown when naming a download - Your active filters are displayed when you go to save, making it easier to write an accurate title.
- Rename saved datasets - Edit the title of any saved dataset at any time from your saved datasets list - no re-download needed.

Users can now add the Dewey MCP directly to their ChatGPT interface through the app store.
