Canonical: https://chikaraintel.com/docs/mcp/tools/get_company_ownerships

Group: Companies. Read only.

## When to use

Use it to map a group structure, or to list the funds behind an asset manager. Both directions come back in one call.

Call `search_companies` first.

## Parameters

- `reference` (uuid, body, required) The company's reference UUID.

## Example

Prompt: "What does Ashcombe Capital Partners own?"

  "id": 1,
  "method": "tools/call",

      "reference": "1a2b3c4d-5e6f-4a7b-8c9d-0e1f2a3b4c31"
    }
  }
}
```

Result (invented records):

```json
{
  "organisation": {
    "reference": "1a2b3c4d-5e6f-4a7b-8c9d-0e1f2a3b4c31",
