## About

A `bigquery-get-table-info` tool retrieves metadata for a BigQuery table.

`bigquery-get-table-info` accepts the following parameters:

- **`table`** (required): The name of the table for which to retrieve metadata.
- **`dataset`** (required): The dataset containing the specified table.
- **`project`** (optional): The Google Cloud project ID. If not provided, the
  tool defaults to the project from the source configuration.

The tool's behavior regarding these parameters is influenced by the
`allowedDatasets` restriction on the `bigquery` source:

- **Without `allowedDatasets` restriction:** The tool can retrieve metadata for
  any table specified by the `table`, `dataset`, and `project` parameters.
- **With `allowedDatasets` restriction:** Before retrieving metadata, the tool
  verifies that the requested dataset is in the allowed list. If it is not, the
  request is denied. If only one dataset is specified in the `allowedDatasets`
  list, it will be used as the default value for the `dataset` parameter.
