Credentials it needs

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_ALLOW_UNAUTHENTICATEDSet to 1 to run a non-loopback bind with NO API key on purpose (lifts the startup refusal; the network is then your boundary)
IRIS_DB_PATHSQLite database path
IRIS_LOG_LEVELLog level: debug, info, warn, error
IRIS_HOMEDirectory for the database, custom rules and preferences (default ~/.iris)
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_LLM_JUDGE_MAX_COST_USD_PER_EVALHard cap on the worst-case cost of one judge or citation call (default 0.25)
IRIS_CITATION_ALLOW_FETCHLet verify_citations fetch URLs (off by default)
IRIS_DASHBOARDStart the dashboard alongside the server (same as --dashboard)
IRIS_DASHBOARD_PORTDashboard port (default 6920); IRIS_PORT is the MCP HTTP transport port (default 3000)
IRIS_PORTMCP HTTP transport port (default 3000); only used with --transport http

IRIS_CITATION_DOMAINSComma-separated domain allowlist for verify_citations fetches (only consulted when IRIS_CITATION_ALLOW_FETCH is on)
IRIS_TRANSPORTTransport: stdio (default) or http; same as --transport
IRIS_HOSTBind host for the HTTP transport (default 127.0.0.1); only used with --transport http
IRIS_ALLOWED_ORIGINSComma-separated Origin allowlist for the HTTP transport and dashboard CORS (default http://localhost:*)
