Overview

Description from the maker (original English)

Ask your plant: live PLC data, alarms, history, OEE and reports from your on-premises PLCGateway.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: PLCGATEWAY_URL, PLCGATEWAY_TOKEN

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: PLCGATEWAY_URL, PLCGATEWAY_TOKEN

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "plcgateway": {
      "command": "npx",
      "args": [
        "-y",
        "@plcgateway/mcp"
      ],
      "env": {
        "PLCGATEWAY_URL": "your-value",
        "PLCGATEWAY_TOKEN": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add plcgateway --env PLCGATEWAY_URL=your-value --env PLCGATEWAY_TOKEN=your-value -- npx -y @plcgateway/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "plcgateway": {
      "command": "npx",
      "args": [
        "-y",
        "@plcgateway/mcp"
      ],
      "env": {
        "PLCGATEWAY_URL": "your-value",
        "PLCGATEWAY_TOKEN": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "plcgateway": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@plcgateway/mcp"
      ],
      "env": {
        "PLCGATEWAY_URL": "your-value",
        "PLCGATEWAY_TOKEN": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • PLCGATEWAY_URL required env
    Address of your PLCGateway SCADA or Connect, e.g. http://192.168.1.50:8080
  • PLCGATEWAY_TOKEN secret required env
    API token (PLCGateway → Settings → API token), or the MCP configuration token for device/tag setup

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is PLCGateway safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PLCGATEWAY_URL, PLCGATEWAY_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, zanadir

PLCGateway MCP

Connect AI assistants to your plant through PLCGateway.

PLCGateway connects PLCs, CNC machines and controllers (Siemens S7, Modbus, Mitsubishi, Omron, Allen-Bradley, OPC UA and more), and every PLCGateway product has an MCP server built in. This package is a small stdio bridge: MCP clients that start servers as a command (Claude Desktop, Cursor, Cline, Windsurf, …) run it, and it forwards everything to *your* PLCGateway on your network.

AI client ──stdio──▶ @plcgateway/mcp ──HTTP (your network)──▶ PLCGateway on your premises ──▶ PLCs & machines
  • PLCGateway runs on your premises. The bridge talks only to the address you give it; it collects nothing and sends nothing elsewhere.
  • The assistant works with the rights of the token you give it, the same roles as people.

What you can ask

  • "How many alarms did line 3 have in the last 2 hours?"
  • "What was the filler's OEE today, and where did we lose the most time?"
  • "Summarise the last 24 hours of the tank level trend."
  • "Build a report dashboard with production and energy per shift for line 1." *(draft for you to review)*
  • "Add the Modbus TCP meter at 192.168.1.40 as 'Compressor 2 energy meter'." *(needs the MCP configuration token)*

Requirements

  • PLCGateway SCADA or Connect, reachable from the computer running the AI client, with MCP enabled
  • An API token: PLCGateway → Settings → API token (operator rights: read, write, alarm acknowledgement)
  • Node.js 18.17 or newer

For setup work (adding devices and tags) create the MCP configuration token in Settings and switch it off when done.

Setup

Claude Desktop, Cursor, Cline and other stdio clients
{

"mcpServers": { "plcgateway": { "command": "npx", "args": ["-y", "@plcgateway/mcp"], "env": { "PLCGATEWAY_URL": "http://192.168.1.50:8080", "PLCGATEWAY_TOKEN": " " } } } }

Clients that support HTTP MCP directly

You don't need this package; connect straight to PLCGateway:

{ "mcpServers": { "plcgateway": { "type": "http", "url": "http://192.168.1.50:8080/mcp",

"headers": { "Authorization": "Bearer " } } } }

On the PLCGateway computer itself

plcgateway-scada --mcp-stdio (or plcgateway-connect --mcp-stdio) can be added as the command directly.

Configuration

VariableFlagDescription
PLCGATEWAY_URL--urlPLCGateway address, e.g. http://192.168.1.50:8080 (/mcp is added if missing)
PLCGATEWAY_TOKEN--tokenAPI token or MCP configuration token. Prefer the environment variable.
PLCGATEWAY_TIMEOUT--timeoutRequest timeout in seconds (default 120)

For HTTPS with your own certificate authority, set NODE_EXTRA_CA_CERTS=/path/to/ca.pem.

Troubleshooting

The bridge logs to stderr (visible in your client's MCP logs).

MessageWhat to check
PLCGateway not reachableAddress and port, firewall, PLCGateway running
HTTP 401/403The token (Settings → API token); a regenerated token replaces the old one
HTTP 404MCP is disabled in PLCGateway settings, or the URL points elsewhere
