About
MCP server for IQMS (DELMIAworks) ERP — manufacturing, inventory, production, and quality.
Security Report
The iqms-mcp server enforces fail-closed HMAC-based S2S authentication on HTTP, rejects placeholder secrets, scopes per-request credentials via AsyncLocalStorage, and uses Oracle read tools plus gated WebAPI writes that match its ERP purpose. Only minor concerns remain: the stateless transport design requires ongoing review, and the snippet of server-dispatch tests is truncated so its dispatch logic could not be fully verified. No malicious patterns, hardcoded secrets, or shell execution were found in the provided code. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 1 high severity).

iqms-mcp
MCP server for IQMS / DELMIAworks (EnterpriseIQ), the manufacturing ERP from Dassault Systèmes.
Status: Read tools issue queries through
@wyre-technology/node-iqmsagainst the Direct Oracle path (always available). Write tools route through the licensed DELMIAworks WebAPI module — an optional add-on — and throwDriverNotConfiguredErroruntilX-IQMS-WebAPI-Base-URLcredentials are supplied.
Why this exists
EnterpriseIQ doesn't have a public REST API. The realistic integration paths are:
- Direct Oracle (universal at every install) — read-only queries
- 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 domainiqms_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 \

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
