Call `generate_chart` with your dataset, chart config, a `chart_name`, and `save_chart=False`. It returns an `explore_url` backed by a cached `form_data_key`, which lets Explore open the unsaved chart without a database row [[1]](https://app.dosu.dev/a28d3c7e-a9d3-459e-9fb6-3a6f9ff4f357/documents/0ba1c006-df67-4b5e-860a-193e06b1e5a7) [[2]](https://github.com/apache/superset/pull/36539). 2. Open that link. It's the same unsaved preview in both 3a and 3b. 3a. No tool in the agent's toolset reads back edits you make by hand in Explore. The MCP tools only know what was passed to them (or to `update_chart_preview`), not what you click or type in the UI afterward. If you add axis titles directly in Explore, click Explore's own Save button there. That persists exactly what you edited, name included [[3]](https://github.com/apache/superset/pull/39908). To stay in chat instead, skip editing in Explore and tell the agent the axis-title change. It calls `update_chart_preview` with the `form_data_key` and the updated config, which returns a new preview and `form_data_key` for you to review [[4]](https://github.com/apache/superset/pull/40077) [[5]](https://github.com/apache/superset/pull/39383). 3b. No changes are needed, so go straight to step 4. 4. To save from chat (after 3b, or after iterating with `update_chart_preview` in the chat-driven 3a variant), ask the agent to persist the chart. It calls `generate_chart` again with `save_chart=True` and the same (or updated) config and `chart_name`, which creates the saved chart row [[1]](https://app.dosu.dev/a28d3c7e-a9d3-459e-9fb6-3a6f9ff4f357/documents/0ba1c006-df67-4b5e-860a-193e06b1e5a7) [[2]](https://github.com/apache/superset/pull/36539). This creates a new chart rather than converting the original preview into a saved record, because previews are cached form data with no database identity. `update_chart` only works once a chart has an `identifier`, meaning after it's saved, so it isn't part of this pre-save flow [[6]](https://github.com/apache/superset/pull/41922). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Share context across your team and agents.
