Anthropic has officially launched the Claude Apps Gateway for Amazon Bedrock and Google Cloud, coinciding with Claude models becoming generally available on Microsoft Foundry via Azure, establishing a unified enterprise control plane across all three major hyperscalers. The gateway functions as a plug-and-play proxy that lets developers use agentic tools like Claude Code without managing fragmented API keys, risking security leaks, or running up unmonitored token bills. Its core mechanism relies on a single configuration hook, as Claude Code and the Anthropic SDK look for an environment variable called ANTHROPIC_BASE_URL, intercepting traffic transparently and dynamically mapping workloads to the preferred cloud backend. The gateway introduces native infrastructure controls including identity mapping and audit trails that log the human developer and scope tool execution to specific conversations; per-developer, per-team, or organization-wide budget ceilings that enforce hard cutoffs and automatically revoke access; protocol dialect translation allowing tools built for the Anthropic SDK to interface with Vertex AI or Bedrock without code changes; and zero-latency data compliance for PHI/PII in highly regulated environments.
