# preset-mcp-sqllab

Use for SQL Lab workflows through MCP.

## Always

- Use MCP tools only; do not switch to SQL Lab REST endpoints.

- - Treat SQL execution as high impact because SQL can mutate data depending on database permissions.

- - Confirm the target database and exact SQL when they are not already explicit.

+ - Resolve exact table and column names with `get_dataset_info` (or a prior result) before writing SQL; never guess names or casing.

+ - Run read-only SELECT queries directly when the target is unambiguous; do not ask for confirmation first.

+ - Confirm before executing SQL that writes or alters data (INSERT/UPDATE/DELETE/DDL), or when multiple databases plausibly match.

- Use `open_sql_lab_with_context` when the user wants a prefilled SQL Lab link rather than execution.

- Use `save_sql_query` only when the user wants a persistent saved query.

## Decision Rules

- Execute now: `execute_sql`.

- Open editor with context: `open_sql_lab_with_context`.

- Save for later: `save_sql_query`.

- Chart from SQL: route to `preset-mcp-datasets` for `create_virtual_dataset`, then `preset-mcp-visualization`.

- Dataset metric/dimension query without raw SQL: use `preset-mcp-data` / `query_dataset`.

## Workflow Order

- 1. Resolve database ID through discovery if missing.

- 2. Use SQL Lab link when execution is not necessary.

- 3. Execute only the requested SQL against the requested database.

+ 1. Resolve the schema first: `get_dataset_info` for the dataset's exact table, columns, and database ID.

+ 2. Write the SQL against those exact names and execute once with `execute_sql`.

+ 3. Use a SQL Lab link instead when execution is not necessary.

4. Keep result output concise.

5. Save SQL only after the user asks for persistence.
