Every filter is optional. This read serves stored ads and does not collect new ones.

  --header "Authorization: Bearer $PEEKPANDA_TOKEN" \
  --header 'x-genviral-tenancy: personal'
```

## MCP request

Call get_ads with action rails. Path fields go in params, filters in query, and a write body in body.

```
{
  "name": "get_ads",
  "arguments": {
    "request": {
      "action": "rails"
    }
  }
}

```

## Response

rails is empty when nothing is stored. totals uses the same counts as the ranking read.
