Routine Network Access Tiers

Security model for Claude Code cloud routines, controlling which external services a running routine can call.

Tiers

Tier Scope Risk Default?
Trusted Anthropic-vetted domain allowlist (Google, GitHub, Anthropic services) Low Yes
Full Any outbound URL Higher (prompt injection risk) No
Custom User-specified domain list Configurable No

Key points

  • Default is Trusted — sufficient for GitHub repo operations, Google services, and Anthropic APIs [010]
  • Full network access required for third-party services not on Anthropic’s allowlist (e.g., Alpaca Markets, Perplexity API) [010]
  • Full mode increases prompt injection risk: a malicious web response could instruct the agent to take unintended actions [010]
  • Custom tier lets teams specify an exact allowlist — best practice for production routines with defined external dependencies [010]
