Reveal Tunnel Token

$ ant beta:tunnels reveal-token
POST/v1/tunnels/{tunnel_id}/reveal_token

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.

Reveals a tunnel's connector 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.

Parameters
--tunnel-id: string

Path parameter tunnel_id

--beta: optional array of AnthropicBeta

Optional header to specify the beta version(s) you want to use.

--workspace-id: optional string

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
beta_tunnel_token: object{ type: "tunnel_token", id, tunnel_token }

A tunnel's connector token.

type: "tunnel_token"
id: string

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

tunnel_token: string

The connector token used to run the tunnel. Treat as a credential.
