What

Claude Code now sends a small background request to GET /v1/me to prepare its sign-in with the Anthropic API. The request runs quietly without waiting for an answer, retries with a growing delay, and gives up after a timeout. It is skipped unless:

  • the provider is Anthropic's own API (firstParty) and not a gateway, and
  • the policy check allow_api_auth_warm passes.

Two new policy entries are denied for organisations under HIPAA rules when no cached answer is available:

  • allow_api_auth_warm (requirement HIPAA-R59), which controls this warm-up request
  • allow_mcp_task_worker_wake (requirement HIPAA-R57), which controls waking an MCP task worker. MCP is the system that connects Claude Code to outside tools.

Why

The warm-up is a network call Claude Code makes on its own in the background. Organisations under HIPAA rules will not get this warm-up or the MCP task worker wake-up.

The writer flagged doubtWhere the worker-restart policy is checked, and so what exactly stops happening, is not confirmed.
