# Reveal Tunnel Token

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

**Deprecated**

**Deprecated.** This Admin API endpoint is superseded by `/v1/tunnels` on the Claude API and will be removed after a migration window. New integrations should use [`/v1/tunnels`](/docs/en/api/beta/tunnels) with the `anthropic-beta: mcp-tunnels-2026-06-22` header and a WIF token carrying the `workspace:manage_tunnels` scope. Existing integrations continue to work with the `mcp-tunnels-2026-05-19` header and `org:manage_tunnels` scope during the migration window.

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.
