Query SQL Tool
This tool is used to generate a sql query against the LookML model. The
model, explore, and fields list must be specified. Pivots,
filters and sorts are optional.
The model can be found from the get_models tool. The explore
can be found from the get_explores tool passing in the model.
The fields can be found from the get_dimensions, get_measures,
get_filters, and get_parameters tools, passing in the model
and the explore.
Provide a model_id and explore_name, then a list
of fields. Optionally a list of pivots can be provided.
The pivots must also be included in the fields list.
Filters are provided as a map of {"field.id": "condition",
"field.id2": "condition2", ...}. Do not put the field.id in
quotes. Filter expressions can be found at
https://cloud.google.com/looker/docs/filter-expressions.
Sorts can be specified like [ "field.id desc 0" ].
An optional row limit can be added. If not provided the limit
will default to 500. "-1" can be specified for unlimited.
An optional query timezone can be added. The query_timezone to
will default to that of the workstation where this MCP server
is running, or Etc/UTC if that can't be determined. Not all
models support custom timezones.
The result of the query tool is the sql string.
