Use Superset MCP data-returning tools for chart data, chart previews, rendered chart SQL, and dataset query results. Use only for MCP tool workflows; do not use for direct API work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# preset-mcp-data Use when the user needs data returned through MCP tools. ## Always - Use MCP tools only; do not switch to REST chart-data, SQL Lab, or dataset endpoints. - Treat returned rows, rendered SQL, chart previews, and dataset query results as potentially sensitive. - Keep row limits, selected columns, metrics, filters, and formats narrow. - Use discovery tools first when identifiers, metrics, columns, or chart IDs are unknown. - Do not use data tools as a workaround after data-model permission denial. ## Decision Rules - Use `get_chart_data` for existing chart result data. - Use `get_chart_preview` for renderable existing chart previews. - Use `get_chart_sql` to inspect rendered chart SQL without executing it. - Use `query_dataset` for semantic-layer metrics, dimensions, filters, and time ranges (saved metrics only; route ad-hoc aggregates to `preset-mcp-sqllab`). - Route chart creation to `preset-mcp-visualization`. ## Workflow Order 1. Classify which output the request needs: result data, preview content, SQL text, or semantic-layer output. Do not ask the user to re-confirm an explicit data request. 2. Resolve the object and schema through discovery if needed. …

How to install
mdr add preset-io/agent-skills/preset-mcp-data@sha256:9433f6d353f54115The line at the top of this page pins the label git:20260611.c022218, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
