Product Update: What's New in UAC 8.0

Discover Robi AI in UAC 8.0, with LLM-powered workflows, root cause analysis, natural language automation, and MCP integration, plus 25+ customer-requested enhancements and UDMG 3.3 updates.

Robi AI is the reason UAC 8.0 matters. Gwyn Clay calls it the biggest jump in Universal Automation Center in the past ten years, and it's the product of about two years of work. An early version was demonstrated at UserVerse in late 2024, then substantially rebuilt as the underlying standards moved, MCP among them. The name comes from the mascot that has been sitting on the Stonebranch shield for years.

Five design principles shaped it. The architecture is modular, because AI standards are still moving and the platform has to survive that. The design is transparent, since this ships on premises as well as SaaS and customers need to see what's behind each feature and how to extend it. It's optional, installed alongside UAC rather than forced on anyone. It's private: each customer gets their own instance, no customer data is shared, and no model training happens on your data. Your LLM is yours, so any training is your model on your data. And there's a human in the loop at every step, with a manual confirmation before anything moves forward.

You choose the model. Azure OpenAI, Amazon Bedrock, Google Vertex, and Claude all work, as does a self-hosted model if you'd rather stay offline entirely. Robi AI has a one-to-one relationship with UAC and the AI server.

The architecture is deliberately conventional. A separate AI service sits alongside UAC. Stonebranch built the Robi orchestration layer. Below it sit the AI services: the LLM and vector database, plus the standard pieces, tools, RAG, and memory. An agentic layer supports AI agents, which will open up to partners and customers. And an MCP client and server let you reach Robi AI from elsewhere, whether from an LLM directly or from one embedded in a platform like ServiceNow or SAP, while the client can call out to other MCP servers.

Three contexts: build, run, and integrate.

Integrate is the foundation. The MCP server carries the tools and capabilities that let Robi interact with UAC, other tools, and AI endpoints. Alongside it is a new AI-powered extension builder that has cut extension development from days to hours. It's being demonstrated to select customers now and will roll out more broadly.

Run is where most people will meet it. Point Robi at your LLM and load the documentation into your vector database, then enable it in the administration section. Only then does the assistant icon appear at the top right. Everything in the chat happens in the context of your logged-in user, including your permissions, so Robi cannot do anything you couldn't do yourself.

David walks through three examples. Launching a task: type the request, Robi asks the reason for audit purposes, spots the task's variables, asks whether to use the defaults or change them, takes natural language edits, confirms the final set, launches, and hands back a button to open the task instance. Querying status: ask for all tasks with an EOD prefix in a problem state over the last twelve hours and Robi knows what problem state means, returning a list with direct links. Then ask for the same results as CSV for an Excel import and it reformats with a copy button, which is the LLM doing work UAC alone couldn't.

Root cause analysis is the one to watch. Right-click a failed task in the activity window and choose Analyze Now. Robi reads the output, identifies the root cause, in the demo a script that needed to be time zone aware, then offers to analyze the script in more detail. It presents a fix, tells you what it intends to change, shows you the exact portion of the script, then offers to update it and rerun the task. Run it against a workflow and it finds every failed task down through the sub-workflows, with an analyze button on each. It can also generate an action URL you can send to a colleague that drops them straight into the failed workflow.

Build is documentation and LLM knowledge in one place. Ask how to create a workflow containing three specific existing tasks running in sequence and you get step-by-step instructions plus a documentation link. Notably, the workflow build tool isn't in the MCP yet, and it's a near-term priority; once it lands, a button appears offering to build it for you. Ask for an example of offsetting a date by a year with a function and Robi finds the right function and shows the usage. The strongest example combines everything: ask how to create custom days via the REST API for every public holiday in England in 2026 and generate the JSON for each, and Robi pulls the holidays from the LLM, the API call from the documentation, and the JSON format from both, delivering copy-ready output. Ask for a Python script to convert date formats and it writes one you can paste into the script library, where root cause analysis will help you fix it if it misbehaves.

About 25 customer-requested enhancements also shipped. MS Graph support arrives for outbound email connections, driven by customers no longer permitted to use SMTP, with inbound support to follow for the email monitor. Object versions can now be diffed, either two versions against each other or one version against the current active one, with changes highlighted. The approval task from 7.9 gains connector conditions so a task can fire when an approval enters approval-required status, which is how you'd wire in a ticketing or messaging system, plus an operational memo field to record why something was approved or rejected. Date functions no longer have to resolve against the server time zone; you can now use the task's own, which matters for globally distributed workloads. Web service API additions cover report interaction, selecting steps for rerun on z/OS, promotion schedule and reschedule, and task instance and trigger improvements. On security, agent registration with an OMS can be restricted to members of the same business service. For z/OS: TLS 1.3 sessions, agent file monitor filtering by job name, SNC connections to SAP from USAP on z/OS, which previously worked only on Windows and Linux, and z/OS 3.2 certification, which required adjustments for changed default ciphers in System SSL. IBM i adds job log retrieval, PDF conversion for email notifications, and variables in job names.

UDMG 3.3 rounds out the session. Robert Oslin frames the split: Universal Data Mover handles transfers inside your organization, while UDMG handles B2B exchange with partners at the network edge, with Secure Proxy moving data through the DMZ. The release focuses on automation, innovation, and core managed file transfer.

On automation, UDMG could previously only trigger a UAC workflow when files were received. Now it triggers on staged files, on transfer errors, and on files retrieved by a partner, covering UDMG acting as both client and server. A new run command action executes locally on the UDMG system before or after publishing an event, so you can rename, delete, or decrypt a file in place, and run commands and publish events can both be stacked.

The innovation piece is a new cloud endpoint type joining SFTP, AS2, and local file system. UDMG can receive a file and stream it straight to Google, AWS, or Azure without it ever touching the UDMG filesystem. The partner sees what looks like a local directory. That turns UDMG from a point solution into an actual gateway and removes a two-step hop into the cloud. Business services tags add a layer of access control on top of the existing role and permission model, so different business units can be scoped to different endpoints and pipelines.

Secure Proxy adds a direct pass-through mode alongside session break, with the tradeoffs documented and a blog post coming. Active-active clusters get built-in health checks so the load balancer can route around an unhealthy node, and Microsoft SQL Server joins Oracle and the built-in SQLite as a database option. Elsewhere: wildcard support for remote get and remote put, which were single-file operations before, log segregation by type for troubleshooting, security controls moved out of configuration files into the UI, new password complexity policies covering reuse and repeating characters, and continued performance work aimed at customers moving millions of files a day.

Key Takeaways:
