Get Tunnel

$client->beta->tunnels->retrieve(string tunnelID, ?list<AnthropicBeta> betas, ?string workspaceID): BetaTunnel
GET/v1/tunnels/{tunnel_id}

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.

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