Use Siemens Opcenter with AI via MCP
Opcenter brings manufacturing execution, detailed scheduling and quality management together – exactly the information people ask about most in day-to-day operations. Siemens does not currently offer an MCP server for Opcenter, so the connection to CompanyGPT is built as a custom integration on the existing interfaces of the Opcenter modules.
What is Siemens Opcenter?
Opcenter is the MOM and MES portfolio from Siemens Digital Industries Software. It combines several product lines under one roof: Opcenter Execution for shop floor control, Opcenter APS for detailed scheduling and Opcenter Quality for quality management. The portfolio is part of the Siemens Xcelerator ecosystem and is traditionally operated inside the plant network; Opcenter X adds a cloud-based variant.
For AI agents, Opcenter matters because it documents the current state of production: order progress, resource allocation, inspection results, deviations. Today that data is mostly reachable only through the specialist front ends – anyone without a licence or training ends up calling the shop floor. An assistant that can read the relevant objects and answer in plain language shortens those loops between production, work scheduling and sales.

How to Connect Siemens Opcenter to CompanyGPT
There is currently no MCP server for Opcenter – neither from Siemens nor as a dependable community project. That is not a blocker: the Opcenter modules expose REST and OData interfaces, Opcenter Connect MOM acts as the integration layer towards ERP and automation systems, and Mendix can provide additional services. We build the connection on that foundation as a custom MCP integration.
The approach is deliberately narrow in scope: together with your IT team and your Opcenter owners we define which objects the assistant may read – production orders, operations or inspection lots, for example. Where the interfaces in use come with an OpenAPI description, we generate an MCP server from it and run it as a container inside your CompanyGPT environment. Service accounts and credentials stay there; no detour via third parties is involved.
Which endpoints and authentication methods apply in practice depends on your Opcenter release and deployment: in the Xcelerator and Opcenter X context Siemens works with OAuth2 and OpenID Connect, on-premises typically with dedicated service accounts. We clarify this upfront with your system administration or your Siemens partner. Inside CompanyGPT, role and group settings then determine which departments see the integration at all.
Note for on-premises operation: CompanyGPT runs in your own Azure tenant – so your on-premises network can be connected directly: via a site-to-site VPN (Azure VPN Gateway) or ExpressRoute between your corporate network and the virtual network of your CompanyGPT environment. The system does not need to be publicly reachable; we set up the connection together with your IT team.
Typical Use Cases
How AI agents in CompanyGPT work with Siemens Opcenter
Order status without detours
Work scheduling and sales ask in plain language how a production order is progressing. The agent reads the status from Opcenter Execution and summarizes it with dates and open operations.
Prepare quality data
Quality assurance has inspection results and deviations for a batch collected and returned as a structured draft for the inspection report – sign-off stays with the department.
Explain the schedule
Detailed scheduling queries the resource allocation from Opcenter APS for a given period and receives a readable assessment of capacity, bottlenecks and affected orders.
Frequently Asked Questions
Siemens Opcenter and AI – the most important answers
Is there an official MCP server for Siemens Opcenter?
No. As of August 2026 Siemens does not provide an MCP server for Opcenter, and no mature community project exists either. The connection is therefore built as a custom integration on the documented interfaces of the Opcenter modules.
How is Opcenter connected to CompanyGPT then?
Through the REST and OData interfaces of the modules in use, or via Opcenter Connect MOM. From those API descriptions we generate an MCP server that runs as a container in your CompanyGPT environment and exposes only the objects you approved.
Does Opcenter have to be reachable from the internet?
No. For on-premises installations a secured network link is established between your CompanyGPT environment and the Opcenter system. Exposing the MES publicly is explicitly not required.
What permissions does the AI assistant get in the MES?
Access runs through a dedicated service account whose rights you define. Many projects deliberately start read-only. On top of that, your CompanyGPT administrators control by role and group who may use the integration.
Does production data stay inside the company?
Yes. CompanyGPT runs as an isolated instance in your own cloud tenant, and so does the MCP server for Opcenter. Queried data does not leave that boundary and is not passed on to third parties.
