## MCP tool

`manitu_vserver_vnc_disable`

### Description for the model

Switches off the VNC console of a virtual server (vServer), by its vserver_id from manitu_vserver_list. The server itself keeps running; only the console can no longer be reached. Switched on again later, it gets a new password. Refused with a conflict (vnc_already_disabled) when it is off already. Runs in the background: the answer is the workflow started (see pending_workflow_list of manitu_vserver_get for its progress). Refused with a conflict while another workflow runs on the vServer (blocked_by names it - wait for it, do not retry at once) or while it cannot be changed.

### Arguments

- `vserver_id` (integer | string, required) - The vserver_id from manitu_vserver_list - never guess one. (pattern `"^[1-9][0-9]*$"`; minimum `1`)

### Example

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "manitu_vserver_vnc_disable",
    "arguments": {
      "vserver_id": 12345
    }
  }
}
```

## REST

`POST https://api.manitu.de/v1/vserver/vnc/disable`

### Authentication

One of `X-API-Key`, `Authorization: Bearer …` - never more than one in a request.

### Request body

JSON; unknown fields are refused.

- `vserver_id` (integer | string, required) - The vserver_id from manitu_vserver_list - never guess one. (pattern `"^[1-9][0-9]*$"`; minimum `1`)

### Response

In `data`; the rest of the body as on every call.

- `workflow` (string, required) - What is being done, e.g. a reboot. (one of `"create"`, `"destroy"`, `"power_start"`, `"power_stop"`, `"power_reboot"`, `"reinstall"`, `"ptr_set"`, `"vnc_enable"`, `"vnc_disable"`, `"rescuesystem_enable"`, `"rescuesystem_disable"`, `"snapshot_create"`, `"snapshot_delete"`, `"snapshot_delete_all"`, `"snapshot_revert"`, `"telemetry_await"`, `"iso_eject"`)
- `workflow_id` (string, required) - The id of this run of the workflow.
- `created_at` (string | null, required) - When it was asked for. (format `date-time`)
- `started_at` (string | null, required) - When it started; null while it waits for the next run - usually a minute or two, at times longer. Nothing to tell the customer unless asked. (format `date-time`)
- `workflow_token` (string | null, required) - Pass it to manitu_workflow_get to see how far the workflow is - as it is, never built or changed. A secret of this workflow: do not show it to anyone. null if there is none.
- `task` (object, required) - The task the customer panel polls for its progress.
  - `task.id` (integer, required)
  - `task.auth` (string, required)

### Statuses

- `200` Success.
- `400` The request does not match the declared input schema.
- `401` No credential was presented, or it was not recognised.
- `403` The credential is not permitted to use this operation.
- `500` The server failed. Nothing about the request was wrong. Whether a change took effect is not known - check before trying it again.
- `503` The channel this operation forwards through is unavailable.

### Example

```sh
curl -X POST 'https://api.manitu.de/v1/vserver/vnc/disable' \
  -H 'X-API-Key: $API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"vserver_id":12345}'
```
