Use only for MCP tool workflows; do not use for direct API work.\n---\n\n# preset-mcp-datasets\n\nUse for dataset-centered MCP workflows.\n\n## Always\n\n- Use `list_datasets` and `get_dataset_info` for dataset discovery.\n- Respect permission-denied responses; do not work around them with chart, dashboard, SQL, or API calls.\n- 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.\n- Use `query_dataset` for semantic-layer data results.\n- Use `create_virtual_dataset` only when the user wants to save SQL as a chartable dataset.\n\n## Decision Rules\n\n- Metadata only: `list_datasets`, `get_dataset_info`.\n- Result table from metrics/dimensions: route through `preset-mcp-data` / `query_dataset`.\n- SQL-to-chartable-dataset workflow: `create_virtual_dataset`.\n- Visualization from dataset: route to `preset-mcp-visualization`.\n- Database discovery: use `list_databases` and `get_database_info` through discovery.\n\n## Workflow Order\n\n1. Find the dataset with one list/search call (use a search filter and sufficient `page_size`); paginate or refine the filter only when the target is not in the returned page.\n2. Inspect columns and metrics with one `get_dataset_info` call before data or chart workflows.\n3. Query semantic-layer results only when the user asks for data.\n4. Save virtual datasets only when persistence is requested.\n\n## Retrieve\n\n- Dataset workflows: [references/dataset-workflows.md](references/dataset-workflows.md)\n"
