Models
class BetaTunnel { $type = 'tunnel'; $id; $archivedAt; /* 3 more */ }
"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.

class BetaTunnelToken { $type = 'tunnel_token'; $id; $tunnelToken; }
"tunnel_token" type
string id

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

string tunnelToken

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