Environment variables
  • IRIS_API_KEYsecretAPI key for HTTP authentication. Required to bind the HTTP transport or the dashboard beyond loopback (0.0.0.0, a LAN address, a container): without it the server refuses to start
  • IRIS_ANTHROPIC_API_KEYsecretEnables evaluate_with_llm_judge and verify_citations with an Anthropic model. Optional: the deterministic rules never need a key
  • IRIS_OPENAI_API_KEYsecretEnables evaluate_with_llm_judge and verify_citations with an OpenAI model. Optional: the deterministic rules never need a key
  • IRIS_WEBHOOK_SECRETsecretThe signing key of that webhook (any string, or whsec_ + base64); the iris format refuses to run without one

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

[![Iris — listed on Serverdex](https://serverdex.io/brand/badge.svg)](https://serverdex.io/server/io-github-iris-eval-mcp-server?utm_source=badge)

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
