# Archive Tunnel

`$client->beta->tunnels->archive(string tunnelID, ?list<AnthropicBeta> betas, ?string workspaceID): BetaTunnel`

**POST** `/v1/tunnels/{tunnel_id}/archive`

The Tunnels API is in research preview. It requires the `anthropic-beta: mcp-tunnels-2026-06-22` header and may change without a deprecation period. It supersedes the Admin API endpoints at `/v1/organizations/tunnels`, which remain available during a migration window.

Archives a tunnel. Archival is irreversible: every non-archived certificate on the tunnel is archived in the same operation, the hostname is retired and never re-allocated, and the tunnel token is invalidated. Retrying against an already-archived tunnel returns the existing record unchanged.

## Parameters

- `tunnelID: string` (path parameter)

  ID of the tunnel (`tnl_...`).

- `betas?:optional list<AnthropicBeta>` (header parameter)

  This endpoint is in beta: requests must send `mcp-tunnels-2026-06-22` in this header.

- `workspaceID?:optional string` (header parameter)

  Optional header to select the Workspace for this request. The value is a Workspace ID (for example, `wrkspc_011CZkZaBF1tNoB5wlCeusgy`).

  Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

## Returns

- `class BetaTunnel`

  - `"tunnel" type`

  - `string id`

    Unique identifier for the tunnel, prefixed with `tnl_`.

  - `?\Datetime archivedAt`

    RFC 3339 datetime string indicating when the tunnel was archived. Null if it is not archived.

  - `\Datetime createdAt`

    RFC 3339 datetime string indicating when the tunnel was created.

  - `?string displayName`

    Human-readable name for the tunnel (1-255 characters). Null if unset.

  - `string domain`

    Anthropic-assigned hostname for the tunnel. MCP server URLs whose host is a subdomain of this value are routed through the tunnel. Globally unique and never reused, even after the tunnel is archived.

## Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

use Anthropic\Client;
use Anthropic\Beta\AnthropicBeta;

$client = new Client(apiKey: 'my-anthropic-api-key');

$betaTunnel = $client->beta->tunnels->archive(
  'tunnel_id',
  betas: [AnthropicBeta::MESSAGE_BATCHES_2024_09_24],
  workspaceID: 'wrkspc_011CZkZaBF1tNoB5wlCeusgy',
);

var_dump($betaTunnel);
```
