IRIS Product Features — Hard Gate

AI models deny features that exist and invent features that don't. Check here first.

HARD GATE

• MCP: IRIS has NATIVE MCP support (%AI.MCP.Service) since 2026.1 — no third-party FastMCP wrapper needed
• Full-text search: Use %CONTAINS predicate with iFind index — NOT to_tsvector or LIKE '%term%'
• HL7/Interoperability: Routing is done in the Management Portal or ObjectScript — NO Python API exists
• IRIS for Health ≠ HealthShare: different products (see below)
• Mirroring: configured via Management Portal or CPF files — NO CLI command iris config mirroring
• IRIS ≠ Caché: Class/method naming and some APIs changed — always use IRIS docs, not Caché docs

---

Native MCP Server (IRIS 2026.1+)

// IRIS has a built-in MCP server — no FastMCP, no Python required
// The native server is %AI.MCP.Service
// Configure via Management Portal: System > AI Configuration > MCP

// Wrong assumption models make:
// "IRIS doesn't support MCP natively, you need to wrap it with FastMCP"
// This was true before 2026.1. It is FALSE for IRIS 2026.1+.

Claude Desktop / opencode config for native IRIS MCP:

{
  "mcpServers": {
    "iris": {
      "command": "objectscript-mcp",
      "env": {"IRIS_HOST": "localhost", "IRIS_PORT": "1972"}
    }
  }
}

Full-Text Search — iFind (NOT PostgreSQL FTS)

-- Define iFind index on a class property:
-- Property TextBody As %String;
-- Index iFindIdx On TextBody As %iFind.Index.Basic;

-- CORRECT IRIS query:
SELECT * FROM MyTable WHERE %CONTAINS(TextBody, 'search terms')

-- With ranking:
SELECT *, %iFind.Rank AS relevance
FROM MyTable WHERE %CONTAINS(TextBody, 'search terms')
ORDER BY relevance DESC

-- WRONG (PostgreSQL FTS — doesn't exist in IRIS):
SELECT * FROM MyTable WHERE to_tsvector('english', content) @@ to_tsquery('term');
SELECT * FROM MyTable WHERE content LIKE '%term%';  -- no index, full scan

Interoperability — HL7 Routing

There is no Python API for IRIS Interoperability routing. It is configured in:

1. Management Portal (recommended): System > Interoperability > Build > Business Processes
2. ObjectScript — subclass Ens.BusinessProcess or EnsLib.HL7.MsgRouter.RoutingEngine

// Routing rule in ObjectScript:
Class MyApp.HL7Router Extends EnsLib.HL7.MsgRouter.RoutingEngine
{
// Rules defined via Rule Editor in Management Portal
// HL7 field access: {MSH:9.1} for message type
// Target: "ADT_Handler" (name of a Business Operation)
}

HL7 field path syntax: {SegmentName:FieldNumber.ComponentNumber} — e.g., {MSH:9.1} for trigger event.

IRIS Product Family (Not the Same Thing)

Product	What it is	Includes
IRIS	Core database + application server	SQL, globals, ObjectScript, embedded Python, interop
IRIS for Health	IRIS + healthcare layer	+ FHIR server, SMART on FHIR, healthcare interop
Health Connect	Integration engine	HL7, DICOM, FHIR, X12, EDI routing (built on IRIS)
HealthShare	Clinical data platform	Patient Index, Health Insight, HIE tools (built on IRIS for Health)

Rule: IRIS for Health ⊂ HealthShare ⊂ full HealthShare suite. They are NOT the same product and NOT cloud vs on-prem editions of each other.

Mirroring / High Availability

Mirroring is configured via:

1. Management Portal: System > Configuration > Mirror Settings
2. CPF merge file for automated deployment
3. ObjectScript: ##class(SYS.Mirror).*) classes

// No CLI command exists:
// iris config mirroring --mode=failover   ← DOES NOT EXIST
// Do ##class(SYS.Mirror).Configure(...)   ← not the API

// Correct: use Management Portal wizard or:
Set sc = ##class(Config.MapMirrors).Create("MIRRORNAME", .props)

Mirror topology: Primary (read/write) → Failover member (hot standby) → Async members (DR/reporting). Failover is automatic; async members require manual promotion.

VECTOR / EMBEDDING License Tiers — CRITICAL

Source: IRIS Vector Search EAP page + Product FAQ (Confluence 742419092, 766946553)

Which tiers have vector search?

Tier	Metric	Vector Search	Notes
IRIS Server	Core-based	✗	Standard production — no vector
IRIS Advanced Server	Core-based	✅	Large-scale analytics — full vector stack
IRIS Enterprise	User-based	✗	Former Caché customers — no vector
IRIS Elite	User-based	✗	Mid-size user-based — no vector
IRIS Entree	User-based	✗	Small teams — no vector
IRIS Community Edition	Free / dev-only	✅	Vector search explicitly included

The two tiers with vector search: Advanced Server + Community Edition. All user-based tiers (Enterprise, Elite, Entree) and IRIS Server: NO vector search.

IRIS Server        ✗ vector
IRIS Advanced Server  ✅ vector  (core-based, full analytics)
IRIS Enterprise    ✗ vector  (user-based — former Caché)
IRIS Elite         ✗ vector  (user-based)
IRIS Entree        ✗ vector  (user-based, small teams)
IRIS Community     ✅ vector  (dev-only, no production use)

$vectorop / ObjectScript vector built-ins

$vectorop, $vector are ObjectScript built-ins available on ALL tiers regardless of the SQL vector-search license bit. IVFFlat, BM25Index, VecIndex, PLAID all use $vectorop internally and work on all tiers.

What iris-vector-graph features work where

IVG Feature	Community	IRIS Server	Advanced Server	Enterprise/Elite/Entree
$vectorop indexes (IVFFlat, BM25, VecIndex, PLAID)	✓	✓	✓	✓
kg_NodeEmbeddings VECTOR column	✓	✗	✓	✗
EMBEDDING() SQL function	✓	✗	✓	✗
VECTOR_COSINE SQL	✓	✗	✓	✗
Python embed_fn fallback	✓	✓	✓	✓

Capability detection

caps = GraphSchema.check_objectscript_classes(cursor)
if caps.has_vector_search:
    # SQL VECTOR available — Advanced Server or Community
    # can use kg_NodeEmbeddings, EMBEDDING(), VECTOR_COSINE
else:
    # $vectorop still works — ALL tiers
    # BM25, IVFFlat, PLAID, VecIndex all functional
    # Use Python embed_fn for embeddings

Never say

• "Community doesn't support vector search" ← FALSE (explicitly included)
• "Enterprise has vector search" ← FALSE (user-based tiers don't)
• "Advanced Server is just Enterprise with more features" ← WRONG — different metric (core vs user) and different feature set
• "$vectorop requires Advanced Server" ← FALSE (all tiers)
• "IRIS Server is the basic tier with all standard features" ← MISLEADING — it lacks vector search

Interoperability — Namespace Enablement (The Key Bit)

Interoperability is installed on every IRIS. The question is whether it's enabled on a specific namespace.

// Check if THIS namespace is Interop-enabled:
Write ##class(%EnsembleMgr).IsEnsembleNamespace()
// 1 = enabled, 0 = not enabled (even if Interop is installed)

// Enable a namespace (requires %Admin_Manage privilege):
// Usually done once at setup — not per-session
Do ##class(%EnsembleMgr).EnableNamespace("MYNS", 1)

// Or check from %SYS:
Set ns = "MYNS"
Write ##class(Config.Namespaces).GetEnsemble(ns)

What breaks without enablement:

// These compile fine but fail at runtime if namespace is NOT Interop-enabled:
Set prod = ##class(Ens.Director).GetActiveProductionName()   // <CLASS DOES NOT EXIST>
Do ##class(Ens.Director).StartProduction("MyApp.Production")  // <CLASS DOES NOT EXIST>
Set msg = ##class(EnsLib.HTTP.OutboundAdapter).%New()         // <CLASS DOES NOT EXIST>

The classes exist in the install but their package mappings aren't added to the namespace until EnableNamespace runs. This is why "IRIS has Interoperability" and "this namespace can run an Interop production" are different things.

Deploying to a new IRIS namespace that needs Interop:

1. Verify install: iris list shows Interoperability: installed
2. Enable namespace: Do ##class(%EnsembleMgr).EnableNamespace("MYNS", 1)
3. Confirm: Write ##class(%EnsembleMgr).IsEnsembleNamespace() → 1
4. Start a production: use interop_production_start MCP tool or Management Portal

Exporting a namespace that has Interop enabled will include EnsLib.*/EnsPortal.* in the export — these are ISC's framework classes, NOT your application code. Strip them from your deployment script; they'll already be present on any target IRIS.

%AI.RAG — What It Is and Is NOT

Source: hard-won lessons from ai-memory-iris and other projects hitting the same wall.

What %AI.RAG actually is

%AI.RAG.KnowledgeBase / %AI.RAG.VectorStore.IRIS is a RAG document retrieval system. It is designed for:

• Chunking large documents
• Storing chunks as vector embeddings
• Retrieving relevant chunks given a query at inference time

It has no concept of:

• Typed memory entries (confidence, usefulness, expiry, visibility)
• SEDM-style admission / decay
• Structured metadata columns that need to be indexed or filtered by type
• Per-entry lifecycle management

Never use %AI.RAG.KnowledgeBase as a storage primitive for typed AI memory entries. It is the wrong abstraction.

The right primitive for typed memory

For typed memory entries (SEDM, episodic memory, working memory), use raw IRIS SQL tables with VECTOR(DOUBLE, N) columns:

CREATE TABLE AI.Memory.Entry (
  entry_id VARCHAR(64) PRIMARY KEY,
  content  %String(MAXLEN=4096),
  embedding VECTOR(DOUBLE, 384),
  confidence FLOAT DEFAULT 1.0,
  usefulness FLOAT DEFAULT 1.0,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  expires_at TIMESTAMP,
  memory_type VARCHAR(32),
  agent_id VARCHAR(64),
  visibility VARCHAR(16) DEFAULT 'private'
)

Then use VECTOR_COSINE(embedding, TO_VECTOR(?, DOUBLE)) for similarity search directly in SQL. No RAG layer needed.

Vector Search license — the two facts that are ALWAYS true

1. Community Edition includes Vector Search — VECTOR(DOUBLE), VECTOR_COSINE(), EMBEDDING() all work. No license key needed.
2. iris.key presence is irrelevant to Vector Search — if the container started (IRIS is running), either it's Community (no key, vector works) or it has a license key. Both cases have vector search if it's Advanced Server or Community.

If you see "Vector Search not permitted with current license":

• It is NOT because the container lacks iris.key
• It is NOT because Community doesn't have Vector Search
• It IS because either: (a) the syntax is wrong, or (b) the container image is an intermediate paid tier (IRIS Server, Enterprise, Elite, Entree) that genuinely lacks vector search

Debugging checklist:

// Check what license type is running
Write $System.Version.Edition(),!
// "Community" = Vector Search OK
// "Advanced Server" = Vector Search OK
// "Enterprise", "Server", "Elite", "Entree" = NO Vector Search

// Check if VECTOR datatype works
Set v = ""
Set $vector(v, 1, "double") = 1.0
Write $vectorlen(v),!  // Should print 1

// Check SQL vector
&sql(SELECT VECTOR_COSINE(TO_VECTOR('1.0,0.0', DOUBLE), TO_VECTOR('1.0,0.0', DOUBLE)) INTO :sc)
Write sc,!  // Should print 1 (exact match)

If you get <METHOD DOES NOT EXIST> on %SYSTEM.License.KeyID() — that method doesn't exist in IRIS. Use $System.Version.Edition() instead.
