UA-.NETStandard
OPC Unified Architecture .NET Standard
UA-.NETStandard is the OPC Foundation's official reference implementation of OPC Unified Architecture for .NET, providing a certified cross-platform stack for industrial automation protocols. The project includes an MCP server that exposes OPC UA client operations as tools for LLMs and AI assistants like Claude and GitHub Copilot, enabling intelligent agents to discover, browse, read, write, and control industrial devices and systems. It also ships a migration agent skill that guides coding agents through upgrading projects from version 1.5 to 2.0. The stack supports client, server, PubSub, GDS, and numerous companion specifications used across manufacturing, energy, robotics, and IoT deployments.
Key Features
Use Cases
- 01Enable LLMs and Copilot to autonomously discover, monitor, and control industrial OPC UA devices and servers
- 02Build AI-assisted manufacturing automation workflows that read sensor data and execute robotic commands
- 03Automate migration of legacy OPC UA .NET projects from 1.5 to 2.0 using coding agents and automated analyzers
- 04Develop intelligent predictive maintenance agents that subscribe to industrial equipment telemetry and alarms
- 05Create vision-guided robotics applications with AI model management and ISA-95 job orchestration
- 06Integrate AI assistants into energy systems, IoT gateways, and industrial control environments via standard OPC UA protocols

UA-.NETStandard — FAQ
What is the UA-.NETStandard MCP server?+
It's a .NET tool and container that exposes OPC UA client operations—browsing servers, reading/writing nodes, subscribing to data changes, and calling methods—as MCP tools that LLMs like Claude and GitHub Copilot can invoke. The MCP server libraries can also be embedded into custom applications alongside other MCP tools.
How do I install the OPC UA MCP server for Claude or other MCP clients?+
Install the .NET tool globally with 'dotnet tool install -g Opc.Ua.Mcp', then configure your MCP client (Claude Desktop, etc.) to launch it as an MCP server. The tool's README at tools/Opc.Ua.Mcp/README.md contains detailed configuration steps for each client.
How do I install the migration agent skill for Copilot or Claude?+
Run 'copilot plugin marketplace add OPCFoundation/UA-.NETStandard' followed by 'copilot plugin install opcua-v20-migration@opcua-dotnet'. The skill automatically guides the agent through installing analyzers, applying fixes, and handling manual migration patterns with context-aware documentation.
What are the prerequisites for using the OPC UA MCP server?+
You need the .NET 8 or later runtime installed to run the MCP server tool. No API keys are required. To connect to industrial OPC UA servers, you'll need their endpoint URLs and appropriate security credentials (certificates or username/password) as configured by your OPC UA server administrator.
Is UA-.NETStandard free to use?+
Yes, the entire stack is licensed under the OPC Foundation MIT License, making it free for commercial and open-source use. Contributors must sign the OPC Foundation Contributor License Agreement (CLA) when submitting pull requests.
Which AI clients and assistants work with the MCP server and migration skill?+
The MCP server works with any MCP-compatible client including Claude Desktop, Copilot, and other LLM tools that support the Model Context Protocol. The migration skill is designed for GitHub Copilot CLI and Claude coding assistants that can discover and execute agent skills.
