About Iris
Iris is an open-source local control plane designed for Claude Code that sits on 127.0.0.1 between the CLI tool and Anthropic. It provides real-time visibility into outgoing context payloads, breaking down token costs across system prompts, tool schemas, and chat history. Iris also helps optimize token usage by pruning inactive tool schemas and enforces security boundaries by evaluating tool calls against deterministic Allow, Ask, or Deny rules before actions execute.
