List Tunnels
GET /v1/organizations/tunnels
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 This Admin API endpoint is superseded by /v1/tunnels on the Claude API and will be removed after a migration window.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 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.
Query parameters
include_archived: optional booleanInclude archived tunnels in the results. Archived tunnels are excluded by default.
default: false
limit: optional numberMaximum number of tunnels to return in a single page.
default: 20, maximum: 1000, minimum: 1
page: optional stringOpaque pagination cursor from a previous response's
next_page. Omit to fetch the first page.workspace_id: optional stringReturn only tunnels in this Workspace. Accepts a
wrkspc_-prefixed Workspace ID; omit to list tunnels across all Workspaces.

Archive a tunnel. Archival is irreversible.
Every non-archived certificate on the tunnel is archived in the same operation, the hostname is retired and never re-allocated, and the tunnel token is invalidated. Retrying against an already-archived tunnel returns the existing record unchanged.
