-## Create Tunnel
+**POST** `/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.
 
 Creates a tunnel. Creation allocates a fresh hostname and provisions the tunnel; it is not idempotent. The new tunnel rejects MCP traffic until at least one CA certificate is added.
