List Tunnels

Deprecated

GET/v1/organizations/tunnels

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 This Admin API endpoint is superseded by /v1/tunnels on the Claude API and will be removed after a migration window.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 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.

List the organization's tunnels.

Results span the caller's organization, ordered by creation time (newest first). Use workspace_id to filter to a single workspace; archived tunnels are excluded unless include_archived is set.
