Understand existing projects
Read topology, rooms, devices, group addresses and links in a structured way – without exports or stale copies.
Version 1.1.0.0 · Release 1
Your AI assistant works right inside the ETS project.
KNX-MCP connects the open ETS project to your AI assistant through MCP. Devices, group addresses, parameters, building structure and bus data become available where you already work – directly in ETS.
Currently available free of charge in the KNX Online Shop.

Inside ETS
Real transparency instead of a black box.
The live monitor shows connected clients, tool calls and telegram activity. Permissions can be set per tool to allowed, confirmation required or blocked.
Architecture
AI and ETS – without an export in between.
The assistant works with the current open ETS project. By default the MCP endpoint stays on localhost.

Default binding is 127.0.0.1; network access must be enabled deliberately and protected with an access key.
In practice
Where KNX-MCP pays off.
From understanding an unfamiliar project to commissioning and troubleshooting.
✓
Check before handover
Collect missing datapoint types, unlinked objects, unusual sender/receiver structures and other findings.
＋
Extend the project
Add rooms, functions and group addresses following the existing scheme and link communication objects.
↯
Commission & troubleshoot
Listen to bus traffic, read current values, send values intentionally, identify devices and scan lines.
☑
Keep track of open items
Read, add and complete ETS to-do items and evaluate them together with project history.
≡
Document
Compile room, device and address information from the actual project for maintenance and acceptance.
Ask naturally
You do not have to remember group address numbers.
KNX-MCP searches by room, trade, name, datapoint type and ETS function – including synonyms, umlauts and common spelling variants.
Which presence detectors on the 2nd floor are not linked to a lighting group yet?
Which hall lighting group addresses have more than one sender?
Create switch, dimming value and status addresses for meeting rooms 2.01 to 2.06.
What is the current temperature in the server room?
Control
The AI can only do what you allow.
Reading works immediately. Changes, telegrams and device programming are controlled separately.
Data
Your project data stays under your control.
KNX-MCP does not operate a cloud service your project data passes through. The app works inside ETS; you decide which assistant processes the data. A locally hosted model is possible as well.
⌂
No KNX-MCP cloud server
The app does not send project data to a Gerald Docenko server. The local log remains on your computer.
◈
Customer data is restricted
Project and contract numbers are only returned on explicit request; security keys are never returned.
∞
Several projects & assistants
ETS5 and ETS6 can expose several open projects through one endpoint; several MCP clients can be connected at the same time.
Community & Support
Questions, bugs and practical experience belong in one public place.
The KNX-MCP Community repository brings together discussions, bug reports, ideas, setup examples and release notes. Please never publish project files, credentials or customer data there.
