## Reveal Tunnel Token

**post** `/v1/organizations/tunnels/{tunnel_id}/reveal_token`

Return the tunnel's current connection token.

The value is fetched live on each call; Anthropic does not store it.
Repeated calls return the same value until the token is rotated.
Exposed as `POST` so the token does not appear in intermediary
access logs.

### Path Parameters

- `tunnel_id: string`

  ID of the Tunnel.

### Header Parameters

- `"anthropic-beta": array of "mcp-tunnels-2026-05-19"`

  Required for all Tunnel endpoints.

  - `"mcp-tunnels-2026-05-19"`

### Returns

- `id: string`

  Stable identifier for the current token value. Changes when the token is
  rotated.

- `tunnel_token: string`

  The tunnel's connection token.

- `type: "tunnel_token"`

  Object type. Always `tunnel_token` for Tunnel Tokens.

  - `"tunnel_token"`
