Claude API and Dome

1. 01

   Add the connection

   Any Claude model id works. Add one connection per model you want agents to reach.

   $ dome models add claude-fable \
     --provider anthropic \
     --model claude-fable-5-1 \
     --api-key "$ANTHROPIC_API_KEY" \
     --gateway prod-gateway

2. 02

   Point your agent at the Gateway

   The Anthropic SDK takes the Gateway URL as its base. OpenAI-compatible clients use the same URL with /v1.

   import anthropic
    
   client = anthropic.Anthropic(base_url=GATEWAY_URL, api_key=DOME_AGENT_KEY)
   client.messages.create(
       model="claude-fable",
       max_tokens=1024,
       messages=[{"role": "user", "content": "Draft a reply to this ticket."}],
   )

Commands and rules tested against a Dome workspace on September 30, 2026. For anything about Anthropic itself, see Anthropic's documentation.

forbid (principal, action == Dome::Action::"llm:invoke", resource is Dome::LLMModel)
when { resource has tier && resource.tier == "frontier" }

  principal has act_as &&
  principal.act_as.groups.contains("ml-research")
