## Auth

Caller's grant must include the `cards:manage` scope. Grants whose scope set is a superset of the required scope are accepted.

## Request examples

<CodeGroup>
  ```bash curl theme={null}
  curl -X POST https://mcp.glide.co/mcp/write \
    -H "Authorization: Bearer $GLIDE_GRANT_TOKEN" \
    -H "Content-Type: application/json" \
    -d '{
      "jsonrpc": "2.0",
      "id": 1,
      "method": "cards.freeze",
      "params": {
        "card_id": "d4e5f6a7-b8c9-0123-defa-234567890123",
        "reason": "anomaly"
      }
    }'
  ```

  ```ts TypeScript theme={null}
  import { GlideClient } from './glide-client';

  const client = new GlideClient({ grantToken: process.env.GLIDE_GRANT_TOKEN! });

  const result = await client.call('cards.freeze', {
    card_id: 'd4e5f6a7-b8c9-0123-defa-234567890123',
    reason: 'anomaly',
  });

  console.log(result);
  ```

  ```python Python theme={null}
  from glide_client import GlideClient
  import os

  client = GlideClient(grant_token=os.environ["GLIDE_GRANT_TOKEN"])

  result = client.call("cards.freeze", {
      "card_id": "d4e5f6a7-b8c9-0123-defa-234567890123",
      "reason": "anomaly",
  })

  print(result)
  ```
</CodeGroup>

## Response examples

Success — card frozen:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "card_id": "d4e5f6a7-b8c9-0123-defa-234567890123",
    "frozen_at": "2026-05-04T14:22:10Z",
    "reason": "anomaly"
  }
}
```

Card not found:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32602,
    "message": "no card d4e5f6a7-b8c9-0123-defa-234567890123",
    "data": { "reason_id": "card_not_found" }
  }
}
```

Card belongs to a different vault:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32001,
    "message": "card d4e5f6a7-b8c9-0123-defa-234567890123 does not belong to vault b2c3d4e5-f6a7-8901-bcde-f12345678901",
    "data": { "reason_id": "card_belongs_to_other_vault" }
  }
}
```

| `-32603` | Internal error  | Issuer-side freeze call failed                                        | Retry — freeze is idempotent; a second call is safe        |
