Reveal Tunnel Token

post /v1/organizations/tunnels/{tunnel_id}/reveal_token

Return the tunnel's current connection 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

  ID of the Tunnel.

Header Parameters

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

  Required for all Tunnel endpoints.

  • "mcp-tunnels-2026-05-19"

Returns

• id: string

  Stable identifier for the current token value. Changes when the token is rotated.

• tunnel_token: string

  The tunnel's connection token.

• type: "tunnel_token"

  Object type. Always tunnel_token for Tunnel Tokens.

  • "tunnel_token"
