opcua_browse_nodes

MCP tool from Opcua MCP by mwieczorkiewicz

Recursively browse from a node up to a depth limit, nesting children under their parent.

How to use it

Project documentation lists opcua_browse_nodes for the Opcua MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

Install Opcua MCP

$docker run -p 8080:8080 -e SERVER_TRANSPORT=http -e OPCUA_ENDPOINT=opc.tcp://your-server:4840 opcua-mcp
