Wincc Unified MCP Xt MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. A Model Context Protocol (MCP) server designed to interface with SIEMENS WinCC Unified SCADA systems via their GraphQL API. This server exposes various WinCC Unified functionalities as MCP tools, enabling AI assistants and.
Once Wincc Unified MCP Xt is connected, these are the calls the assistant has available:
login-user — Logs in with username/passwordbrowse-objects — Browses configured SCADA elementsget-tag-values — Retrieves live tag valuesget-logged-tag-values — Gets historical tag dataget-active-alarms — Lists currently active alarmsget-logged-alarms — Shows previously triggered alarmswrite-tag-values — Updates one or more tagsacknowledge-alarms — Acknowledges alarmsreset-alarms — Resets alarms@modelcontextprotocol/tools on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Wincc Unified MCP Xt's toolset — login-user, browse-objects, get-tag-values and 6 more — is a fair guide to whether it matches your workflow. It is maintained by mrwan84; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
