An MCP server facilitating real-time interaction with OPC UA industrial systems, enabling AI agents to monitor and control operational data.
This server is relatively safe for read-only operations. Write operations pose a moderate risk, as they directly influence industrial systems and depend on the OPC UA server's security measures. Proper configuration and validation are crucial to avoid unintended consequences.
Performance is largely dependent on the OPC UA server's responsiveness and network latency. Consider optimizing network configuration for real-time applications.
Cost is primarily associated with the resources consumed by the Python server and the underlying OPC UA infrastructure. There are no direct API call costs.

}read_opcua_nodeRetrieves the current value of a specified OPC UA node.
Read-only operation; no modification of system state.
write_opcua_nodeWrites a specified value to a given OPC UA node.
Modifies system state, but requires explicit node ID and value.
Browse nodesBrowse and list all opcua nodes.
Read-only operation; no modification of system state.
Read multiple OPC UA NodesRead the value of a specific OPC UA node.
Read-only operation; no modification of system state.
Write to multiple OPC UA NodesRead the value of a specific OPC UA node.

Environment Variable
This server is relatively safe for read-only operations. Write operations pose a moderate risk, as they directly influence industrial systems and depend on the OPC UA server's security measures. Proper configuration and validation are crucial to avoid unintended consequences.
Autonomy depends on the configured permissions of the OPC UA server and the specific node IDs accessed.
Production Tip
Implement robust error handling and input validation to prevent unintended consequences in production environments.
The server should be compatible with any standard-compliant OPC UA server.
Configure the OPC UA server with appropriate security settings, including authentication and encryption.
The server attempts to convert values based on the OPC UA node's data type. Standard OPC UA data types are supported.
Implement error handling in your client application to catch and respond to error messages from the server.
Yes, the server supports reading and writing to multiple nodes in a single request.
Use the 'Browse nodes' tool to discover available nodes and their properties.
Python 3.13 or higher is recommended.
