# Reveal Tunnel Token

POST /v1/tunnels/{tunnel_id}/reveal_token

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.

Reveals a tunnel's connector token. The value is fetched live on each call; Anthropic does not store it. Repeated calls return the same value until the token is rotated. Exposed as POST so the token does not appear in intermediary access logs.

# Path parameters

tunnel_id: string

# Headers

"anthropic-beta": optional array of AnthropicBeta
