Common questions
Is Ganter Lab 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
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 (1.0.3) reached the registry 22 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?

Ganter Lab MCP
Connect Claude, Codex or any assistant with MCP to Ganter Lab, the SCADA station that runs on your computer. The assistant reads live values and history, configures devices, logic and screens, and operates only the areas the station allows.
Ganter Lab must be installed and running on the same computer. This repository holds only the pieces an assistant uses to reach it: the Claude Desktop bundle, the Claude Code plugin and the registry entries. Ganter Lab itself is downloaded from ganterlab.com.
What it does
Ganter Lab is a SCADA station for Windows: it talks to PLCs, meters and sensors over Modbus, OPC UA, Siemens S7, MQTT and other drivers, keeps their history, raises alarms and draws operation screens. Its built-in MCP server lets an assistant work on that station:
- browse the connected equipment and read live values with their quality;
- look through what the station recorded;
- create devices, tags, logic, alarms and screens;
- in the areas you allow, write values and run actions;
- answer questions about the program from the documentation of the version installed.
Nothing leaves the computer. The server listens on the loopback interface only (http://127.0.0.1:18181/mcp, Streamable HTTP) and exists only while the station runs. The station's Agent page decides, area by area behind a master switch, what an assistant may read, configure or operate, and every change an assistant makes is written to the station's event journal under its own name.
Before you connect
- Install Ganter Lab from ganterlab.com and start it.
- Open its Agent page and turn on Enable agent access (MCP). It is off on a fresh install.
- Under Allowed areas, choose what an assistant may do. Reading and most configuring are open as soon as agent access is on; everything that reaches live equipment stays off until you turn it on.
- Note the address the page shows. The default is
http://127.0.0.1:18181/mcp; the port is the page's Port field.
Connect a client
Claude Desktop
Download ganter-lab.mcpb from the latest release and open it: Claude Desktop shows its install dialog. If the station's port is not 18181, set the MCP endpoint field to the address the Agent page shows. The Node runtime the bundle needs comes with Claude Desktop. The station's Agent page offers the bundle too (Install in Claude Desktop).
Claude Code
Through the plugin in this repository:
claude plugin marketplace add ganterlab/ganter-lab-mcpclaude plugin install ganter-lab@ganter-lab
Or with one command and no plugin:
claude mcp add --transport http ganterlab http://127.0.0.1:18181/mcpAnother port. The plugin's MCP endpoint setting holds the station's address, filled in with the default, http://127.0.0.1:18181/mcp. If the Agent page shows another port, change that setting to the address the page shows: Claude Code asks for it when the plugin is enabled, and /config lists it afterwards.
Codex
Add the station to ~/.codex/config.toml:
[mcp_servers.ganterlab]url = "http://127.0.0.1:18181/mcp"
Any other MCP client
Any client running on the same computer that takes a Streamable HTTP server address connects to http://127.0.0.1:18181/mcp (the port is the one the Agent page shows). Clients that reach servers from the internet, such as ChatGPT connectors or the Gemini web chat, are not supported: the station listens on this computer only.
The assistant guide covers every client and every area: www.ganterlab.com/en/docs/agent.
What is in this repository
| File | What it is |
|---|---|
bridge.mjs | The Claude Desktop bundle's bridge: it speaks MCP over stdio to Claude Desktop and forwards each message to the station's endpoint. Built-in Node only, no dependencies. When the station restarts (an update relaunches it), the bridge opens a new session and replays the call, so Claude Desktop needs no restart. For debugging it runs alone: node bridge.mjs http://127.0.0.1:18181/mcp |
manifest.json, icon.png | The bundle's manifest and mark. With bridge.mjs they make ganter-lab.mcpb, attached to each release |
plugin/ | The Claude Code plugin, in a folder of its own: what Claude Code installs and Anthropic's directory lists |
.claude-plugin/marketplace.json | The plugin marketplace of this repository, which points Claude Code at plugin/ |
server.json | The entry in the official MCP Registry, io.github.ganterlab/ganter-lab |
glama.json | The maintainers, for Glama |
.github/workflows/publish-registry.yml | Publishes server.json to the MCP Registry from GitHub Actions, run by hand after a release |
This package has a version number of its own, which changes only when the bridge, the manifest or the plugin changes, not with every version of Ganter Lab.
