List Tunnels

$ ant beta:tunnels list

GET/v1/tunnels

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.

Lists tunnels. Results are ordered by creation time, newest first; archived tunnels are excluded unless include_archived is set.

Parameters

--include-archived: optional boolean

Query param: Whether to include archived tunnels in the results. Defaults to false.

--limit: optional number

Query param: Maximum number of tunnels to return per page. Defaults to 20, maximum 1000.
