GET/v1/tunnels/{tunnel_id}/certificates/{certificate_id}

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.

Fetches a tunnel certificate by ID.
