preset-mcp-visualization

name: preset-mcp-visualization description: Use Superset MCP tools for Explore links, chart configuration discovery, chart previews, saved charts, and chart updates. Use only for MCP tool workflows; do not use for direct API work.

Use for chart and Explore workflows through MCP.

Treat "create", "make", or "build" a chart as saved-chart intent: use generate_chart directly. Treat "add" as saved-chart intent only when no dashboard target is named; with a dashboard target, route to preset-mcp-dashboard.
Use generate_explore_link for "show", "visualize", "explore", or "preview" requests with no save intent.
Use get_dataset_info once to resolve exact column and metric names before building the config.
Use get_chart_type_schema only for unfamiliar or complex chart types, or after a config validation error — not for simple bar, line, pie, table, or big-number charts.
Use saved metrics as saved metrics; do not treat metric names as raw columns.
generate_chart request shape: top-level dataset_id (not datasource_id), chart fields nested inside config, and config.chart_type uses the MCP taxonomy, currently common values such as xy, table, pie, pivot_table, mixed_timeseries, handlebars, and big_number — not a Superset viz_type string. If the needed type is not listed or validation fails, trust get_chart_type_schema.
Never fabricate URLs. Use URLs returned by MCP tools.

Creation intent ("create/make/build a chart", or "add a chart" with no dashboard target): generate_chart. Do not substitute an unsaved Explore link.
Preview intent ("show/visualize/explore/preview"): generate_explore_link.
Use update_chart to change an existing saved chart.
Use update_chart_preview only for cached preview form data.
Route adding charts to dashboards to preset-mcp-dashboard.

Resolve the dataset and its exact columns/metrics with one get_dataset_info call.
Build the config and call the tool matching the user's intent (create → generate_chart).
If the call returns a validation error, do not retry the same config blindly: fetch get_chart_type_schema once, fix the config against it, and retry once.
Report success based on the tool response, not assumption.
