Use Superset MCP tools for dataset inspection, semantic-layer querying, and virtual dataset creation. 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-datasets Use for dataset-centered MCP workflows. ## Always - Use `list_datasets` and `get_dataset_info` for dataset discovery. - Respect permission-denied responses; do not work around them with chart, dashboard, SQL, or API calls. - Use saved metrics and dimensions from `get_dataset_info`; `query_dataset` accepts saved metrics only, not ad-hoc expressions. When no saved metric fits, compute the aggregate with `execute_sql` (route to `preset-mcp-sqllab`) instead of guessing metric names or stopping to ask. - Use `query_dataset` for semantic-layer data results. - Use `create_virtual_dataset` only when the user wants to save SQL as a chartable dataset. ## Decision Rules - Metadata only: `list_datasets`, `get_dataset_info`. - Result table from metrics/dimensions: route through `preset-mcp-data` / `query_dataset`. - SQL-to-chartable-dataset workflow: `create_virtual_dataset`. - Visualization from dataset: route to `preset-mcp-visualization`. - Database discovery: use `list_databases` and `get_database_info` through discovery. ## Workflow Order …

How to install
mdr add preset-io/agent-skills/preset-mcp-datasets@sha256:b8f7701ae00f7cbbThe 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.
