List Tunnels

get /v1/organizations/tunnels

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.

• limit: optional number

  Maximum number of tunnels to return in a single page.

• 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.

Header Parameters

• "anthropic-beta": array of "mcp-tunnels-2026-05-19"

  Required for all Tunnel endpoints.

  • "mcp-tunnels-2026-05-19"
