# List Tunnels

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.

# Query parameters

include_archived: optional boolean

Whether to include archived tunnels in the results. Defaults to false.
limit: optional number

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

format: int32
page: optional string

Opaque pagination cursor from a previous list_tunnels response.
