# Read available Google fields

> Find the metrics and dimensions represented in the stored Google data.

Find the metrics and dimensions represented in the stored Google data.

**MCP tool:** `get_ga4_metadata`. **Operation:** read. Uses the authorized connection; no project or content changes are made by this tool.

## Parameters

| Name | Type | Required | Default | Meaning and accepted values |
| - | - | - | - | - |
| `project_id` | string | Yes | `Required` | Project ID from list\_projects. Select the project in the intended workspace and environment. |

## Example call

Replace ID placeholders and example selections with values from your account. This is the `params` object for MCP `tools/call`.

```json theme={null}
{
  "name": "get_ga4_metadata",
  "arguments": {
    "project_id": "PROJECT_ID"
  }
}
```

## Read the response

Returns `linked`, `dimensions`, and `metrics`, including field names and descriptions when linked.

### Fields to use

These selected fields explain the example and the result to preserve. Field presence depends on the response; this is not a complete response schema.

| Field | Meaning and use |
| - | - |
| `linked` | Whether a property link exists. |
| `dimensions` | Available dimension metadata. The observed unlinked response contains no entries. |
| `metrics` | Available metric metadata. An empty list is not a report of zero measurement values. |

## Response example

Selected fields from an observed IQRush Dev response. Lists are shortened and project/run IDs are placeholders. Omitted fields remain available in the actual response.

```json theme={null}
{
  "project_id": "PROJECT_ID",
  "linked": false,
  "dimensions": [],
  "metrics": []
}
```

This observed example has no linked Google property. It demonstrates the unavailable-integration response; it is not a zero-traffic report.

## Important behavior

The metadata describes the available store. The report tool does not accept arbitrary dimensions and metrics as a generic Google API request.

Check tool and payload errors before using the result. [Response handling](/developers/guides/09-responses-and-metrics) explains estimates and empty results; [errors and recovery](/developers/guides/13-errors) covers invalid requests and temporary failures.

HTTP equivalent: [Read available Google fields](/developers/http/http-get-ga4-metadata). HTTP parameters and defaults can differ.
