# Commercial Metals Company (CMC)

> Fortune 500 manufacturer, recycler, and fabricator of steel and metal products (rebar, merchant bar,
> wire rod, performance steel, construction products, ground improvement) serving construction, energy,
> and manufacturing across the United States, Europe, and Asia. CMC operates a customer portal (myCMC)
> and a business-to-business Systems Integration program, but publishes **no public developer portal,
> no API reference, and no machine-readable contract** (no OpenAPI, AsyncAPI, GraphQL, gRPC, WSDL, or
> MCP server was found on any CMC host as of 2026-09-05).

## What exists

- **myCMC customer portal** — web portal for inventory, pricing, online ordering, material release,
  document search, and real-time order/delivery status. Access is granted to CMC customers only.
- **Systems Integration program** — CMC's own one-pager states it supports "EDI, API, .CSV, XML, flat
  files, or custom formats" across the Quote-To-Cash process (inventory status, pricing data, purchase
  order placement and acknowledgement, ASN shipping data, MTR/mill-cert data, electronic billing,
  remittance advice, customer inventory advice). Onboarding is via a CMC sales representative or
  ecommerce@cmc.com — there is no self-service signup, no published endpoint, and no published contract.
