Iqms

MCP server for IQMS / DELMIAworks (EnterpriseIQ), the manufacturing ERP from Dassault Systèmes.

Status: Read tools issue queries through @wyre-technology/node-iqms against the Direct Oracle path (always available). Write tools route through the licensed DELMIAworks WebAPI module — an optional add-on — and throw DriverNotConfiguredError until X-IQMS-WebAPI-Base-URL credentials are supplied.

Why this exists

EnterpriseIQ doesn't have a public REST API. The realistic integration paths are:

1. Direct Oracle (universal at every install) — read-only queries
2. WebAPI module (paid licensed add-on) — transactional writes

This MCP server exposes both behind a single decision-tree-navigated tool surface.

Tools

Initial discovery surface (always available):

• iqms_navigate — list tools in a domain
• iqms_status — credential / connection check

Domains: workorders, inventory, boms, sales_orders, purchase_orders, schedule, quality.

Read tools (Oracle, available always):

Tool	Purpose
iqms_workorders_list	Open / in-progress work orders
iqms_workorders_get	Full work order detail incl. routings
iqms_inventory_onhand	On-hand by item / location / lot
iqms_inventory_lot_trace	Lot genealogy walk
iqms_boms_explode	BOM explosion
iqms_boms_where_used	Where-used reverse lookup
iqms_sales_orders_list	Open SOs / ship status
iqms_purchase_orders_list	Open POs / expected receipts
iqms_schedule_capacity	Machine schedule + capacity load
iqms_quality_ncrs	Non-conformances / CARs / CAPAs

Write tools (WebAPI, gated):

Tool	Purpose
iqms_workorders_create	Create a new work order
iqms_workorders_post_production	Post qty made / scrapped
iqms_inventory_adjust	Inventory transaction
iqms_quality_create_ncr	Open a non-conformance record

Run modes

Local (stdio)

IQMS_ORACLE_USER=eiq_ro \
IQMS_ORACLE_PASSWORD=… \
IQMS_ORACLE_CONNECT_STRING=eiq-db.example.com:1521/EIQ \
npx -y github:WYRE-AI/iqms-mcp

Gateway (HTTP, stateless)

CONDUIT_S2S_SECRET is required. If it is empty or a known placeholder (changeme, placeholder, your-s2s-secret, and the other example values rejected at startup), the HTTP server logs an error and exits non-zero. It never prints the secret. Set MCP_ALLOW_INSECURE_DEV=1 only for local development to start without the secret; the process logs a warning, does not check X-Gateway-S2S, and binds 127.0.0.1 only. A non-loopback MCP_HTTP_HOST (including 0.0.0.0) is ignored in that mode and the override is logged. A placeholder secret still refuses to start.

MCP_HTTP_HOST is honored when CONDUIT_S2S_SECRET is set, and defaults to 0.0.0.0 when unset. With no secret, the listener is 127.0.0.1. The container image sets MCP_HTTP_HOST=0.0.0.0 and AUTH_MODE=gateway.

CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
MCP_TRANSPORT=http \
MCP_HTTP_PORT=8080 \
AUTH_MODE=gateway \
node dist/http.js

Local HTTP without a secret is development-only and always binds 127.0.0.1:

MCP_ALLOW_INSECURE_DEV=1 npm run start:http

X-Gateway-S2S

With MCP_TRANSPORT=http and a real CONDUIT_S2S_SECRET, every /mcp request must include X-Gateway-S2S:

t=<unix seconds>,v1=<hex hmac-sha256>

The signature is HMAC-SHA256 of the literal message t=<unix seconds> (the same t= prefix that appears in the header), keyed with CONDUIT_S2S_SECRET, and hex-encoded. A missing or invalid header returns 401. /health stays unauthenticated and does not read vendor credentials. The stdio transport does not use CONDUIT_S2S_SECRET.

In AUTH_MODE=gateway, /mcp also requires the Oracle headers below. Those headers are the only credential source for that request. A request missing any of them returns 401 and does not fall back to IQMS_* in the process environment.

Header	Required	Notes
X-Gateway-S2S	yes, when CONDUIT_S2S_SECRET is set	t=<unix seconds>,v1=<hmac-sha256 hex of t=...>
X-IQMS-Oracle-User	yes	Oracle DB user
X-IQMS-Oracle-Password	yes	Oracle DB password
X-IQMS-Oracle-Connect-String	yes	Easy Connect or TNS
X-IQMS-WebAPI-Base-URL	no	Enables write tools when all three WebAPI headers are present
X-IQMS-WebAPI-User	no
X-IQMS-WebAPI-Password	no

Single-tenant HTTP (AUTH_MODE=env)

/mcp still requires a valid X-Gateway-S2S header. Vendor credentials come from IQMS_ORACLE_USER, IQMS_ORACLE_PASSWORD, and IQMS_ORACLE_CONNECT_STRING. Optional IQMS_WEBAPI_* variables enable write tools. This mode is separate from the gateway Compose service, which does not inject those variables.

Docker

The image listens on 0.0.0.0 inside the container and defaults to AUTH_MODE=gateway. Publish the port on loopback and pass the S2S secret. In gateway mode, IQMS credentials arrive on each request as headers; they are not read from the environment.

docker build -t iqms-mcp .
docker run \
  -e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
  -p 127.0.0.1:8080:8080 \
  iqms-mcp

Compose refuses to start when CONDUIT_S2S_SECRET is unset, sets AUTH_MODE=gateway, publishes 127.0.0.1:8080:8080, and does not inject static IQMS_* credentials:

CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" docker compose up
