      "command": "python",
      "args": [
        "path/to/opcua_mcp/main.py"
      ],

    }
  }
}

You deploy the OPC UA MCP Server to bridge OPC UA-enabled industrial systems with MCP clients, enabling real-time monitoring, analysis, and control through AI-driven workflows.

How to use

Use this MCP server with your MCP client to read and write OPC UA nodes, browse the namespace, and execute batch operations. You can query a single node’s value, set a node to a new value, read multiple nodes at once, or write several nodes in a single step. These capabilities let you build AI-powered automation and monitoring workflows around your industrial assets.

How to install

Prerequisites include Python 3.13 or higher and access to an OPC UA server (real or simulated). Install the server dependencies and run the MCP client configuration as shown.

Step 1: Install dependencies and clone the project.

git clone https://github.com/kukapay/opcua-mcp.git
cd opcua-mcp
pip install mcp[cli] opcua cryptography

Step 2: Prepare the MCP client configuration to connect to your OPC UA server.
