Rotate Tunnel Token

$client->beta->tunnels->rotateToken(string tunnelID, ?string reason, ?list<AnthropicBeta> betas, ?string workspaceID): BetaTunnelToken
POST/v1/tunnels/{tunnel_id}/rotate_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.

Rotates a tunnel's connector token. Rotation invalidates the current token for new connections and returns a fresh value; established connections are not severed. A connector restarted after rotation must use the new value.

Parameters
tunnelID: string
reason?:optional string

Optional free-text reason for the rotation, recorded for audit.

betas?:optional list<AnthropicBeta>

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

workspaceID?:optional string
Returns
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.
