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 This Admin API endpoint is superseded by /v1/tunnels on the Claude API and will be removed after a migration window.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

Query parameters
include_archived: optional boolean

Include archived tunnels in the results. Archived tunnels are excluded by default.

defaultfalse
limit: optional number

Maximum number of tunnels to return in a single page.

default20
maximum1000
minimum1
page: optional string

Opaque pagination cursor from a previous response's next_page. Omit to fetch the first page.

workspace_id: optional string

Return only tunnels in this Workspace. Accepts a wrkspc_-prefixed Workspace ID; omit to list tunnels across all Workspaces.

Headers
"anthropic-beta": array of AnthropicBeta

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