Common questions
Is TiaLink 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: TIALINK_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 (0.1.1) reached the registry 16 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?

TiaLink — TIA Portal MCP Gateway
TiaLink is a TIA Portal MCP gateway by 汇智网 (hubwiz.com). It lets any MCP-capable AI agent operate Siemens TIA Portal projects directly.
📄 Product page: https://tia.hubwiz.com/tia-link
What it does
TiaLink exposes Siemens TIA Portal capabilities as MCP tools, so an AI agent can:
- Configure hardware & networks — add devices and modules, assign IP addresses, create subnets and IO systems
- Work with programs & data — create FB / FC / DB / UDT blocks, write SCL, import SimaticML (including LAD) blocks
- Build — compile, save, export, and archive projects
- Simulate & verify — download to S7-PLCSIM Advanced, read/write variables, run test scenarios
- Read back — project model, block interfaces, and hardware tree for verification
In short: instead of getting a code snippet in a chat window, the agent operates a real TIA Portal project and reads the result back.
How it works
AI agent (MCP client)│ MCP (Streamable HTTP, endpoint /mcp) ▼ TiaLink ──► Siemens TIA Portal Openness ──► TIA Portal project
- Protocol: MCP (Model Context Protocol), Streamable HTTP, endpoint
/mcp - Underlying: Siemens TIA Portal Openness
- Agent-agnostic: TiaLink does not bind to any specific model or vendor. Any MCP client that supports Streamable HTTP and can send a Bearer header can connect.
Getting started
- Check the machine — Windows, a licensed TIA Portal V19, V20 or V21 (V21 requires TiaLink 1.5.0 or later, verified on real hardware), and the Windows account in the local *Siemens TIA Openness* group. Full checklist: [install.md](./install.md).
- Buy and download — TiaLink is paid software: ¥99/month (China). Buy on the product page; the download link and the setup steps appear immediately after the WeChat Pay payment. Keep the order number — the licence request needs it.
- Point your MCP client at the gateway — ready-made configurations for Claude Code, Cursor, VS Code and Claude Desktop are in [examples/](./examples/README.md).
- Verify — list the tools, read a scratch project, then create one block and require the compile result. If step three fails, see the troubleshooting table in install.md.
If your client only speaks stdio
TiaLink serves Streamable HTTP. Most clients handle that directly, but some desktop hosts and one-click bundles can only launch stdio servers. For those there is a small adapter in this repository, [`server/index.js`](./server/index.js) — it forwards JSON-RPC between stdio and the gateway and adds no functionality of its own.
⚠️ The adapter is not the product. It needs a licensed TiaLink gateway
already running. Without one it fails on the first request — by design.
# Run the adapter against a local gatewayTIALINK_URL=http://127.0.0.1:8080/mcp npx tialink-mcp
Pre-flight: is the gateway reachable, is the token right, which tools exist?
TIALINK_URL=http://192.168.1.78:8080/mcp TIALINK_TOKEN=... npx tialink-mcp --check
| Path | What you get |
|---|---|
npx tialink-mcp | stdio ↔ HTTP adapter (npm, no dependencies, Node ≥ 18) |
manifest.json + .mcpb | one-click desktop bundle — npx @anthropic-ai/mcpb pack . |
Dockerfile | the same adapter in a container, for Linux CI and sandboxed agents |
Configuration is by environment variable: TIALINK_URL (default http://127.0.0.1:8080/mcp), TIALINK_TOKEN, TIALINK_TIMEOUT_MS (default 600000 — compile and download calls are slow on purpose).
Deployment
- TiaLink runs on the same Windows machine as TIA Portal (Openness only runs where TIA Portal is installed).
- The MCP client can run on another machine and connect over the LAN — for example,
http:// :8080/mcp. - Project data never leaves the local network. Suitable for offline and on-premises environments.
- Recommended: configure an API token; the MCP client sends it as a
Bearerheader.
Supported clients
Any MCP client that supports Streamable HTTP and can send a Bearer header, for example:
- Claude Code
- Cursor
- VS Code
TiaLink is not tied to a specific vendor — the same gateway works with different agents (including Tencent WorkBuddy and other MCP clients).
Example MCP configuration
{"mcpServers": { "tialink": { "type": "http", "url": "http://192.168.1.78:8080/mcp", "headers": { "Authorization": "Bearer " } } } }
Replace 192.168.1.78 with the IP or hostname of the machine running TiaLink, and with your configured token. Configurations for specific clients — including one that reads the token from an environment variable instead of the file — are in examples/.

FAQ
What is TiaLink? TiaLink is a TIA Portal MCP gateway by 汇智网 (hubwiz.com). It lets any AI agent operate Siemens TIA Portal projects through the MCP protocol.
Does TiaLink require internet access? No. TiaLink runs on the same machine as TIA Portal, all operations happen locally, and project data stays on-prem.
Does the MCP gateway have to be on the same computer as TIA Portal? The gateway itself must run on the same machine as TIA Portal (Openness requires it). The MCP client, however, can run on a different machine and connect over the LAN.
Is TiaLink tied to one AI vendor? No. TiaLink is agent-agnostic — any MCP client that supports Streamable HTTP with a Bearer header can use it.
Can AI-generated PLC code be used directly? AI handles the verifiable software part, but safety functions must be implemented in hardware (safety relay / safety PLC), hard interlocks must be pneumatic or electrical, and time/sensor tuning must be done on the real machine. TiaLink does not replace safety responsibility.
What does it cost? ¥99/month (China). Multi-seat, floating and air-gapped enterprise deployments are quoted on request — write to support@hubwiz.com.
Is TiaLink open source? No. TiaLink is commercial, closed-source software — the gateway and its engine are not open source. What *is* MIT-licensed is the stdio↔HTTP transport bridge in server/, a thin adapter that does nothing without a licensed, running gateway. Documentation in this repository is CC BY 4.0.
How do I buy it and get a licence? Buy on the product page: after the WeChat Pay payment, the page immediately shows the download link and the setup steps — no account or form required. Install TiaLink as a normal user, open http://localhost:8080/, and send the machine code plus the generated .tlreq request file to support@hubwiz.com. The machine-bound .lic is issued for that machine and works fully offline.
