### Description (declared)

# OPC UA MCP Server 
 
An MCP server that connects to OPC UA-enabled industrial systems, allowing AI agents to monitor, analyze, and control operational data in real time. 
 
This project is ideal for developers and engineers looking to bridge AI-driven workflows with industrial automation systems.

## Features 
 
- **Read OPC UA Nodes**: Retrieve real-time values from industrial devices. 
- **Write to OPC UA Nodes**: Control devices by writing values to specified nodes. 
- **Seamless Integration**: Works with MCP clients like Claude Desktop for natural language interaction. 
 
 
### Tools 
The server exposes two tools: 
- **`read_opcua_node`**: 
  - **Description**: Read the value of a specific OPC UA node. 
  - **Parameters**: 
    - `node_id` (str): OPC UA node ID (e.g., `ns=2;i=2`). 
  - **Returns**: A string with the node ID and its value (e.g., "Node ns=2;i=2 value: 42"). 
 
- **`write_opcua_node`**: 
  - **Description**: Write a value to a specific OPC UA node. 
  - **Parameters**: 
    - `node_id` (str): OPC UA node ID (e.g., `ns=2;i=3`). 
    - `value` (str): Value to write (converted based on node type). 
  - **Returns**: A success or error message (e.g., "Successfully wrote 100 to node ns=2;i=3"). 
 
### Example Prompts 
 
- "What’s the value of node ns=2;i=2?" → Returns the current value. 
- "Set node ns=2;i=3 to 100." → Writes 100 to the node. 
 
## Installation 
 
### Prerequisites 
- Python 3.10 or higher 
- An OPC UA server (e.g., a simulator or real industrial device)
