One connector, every AI
Rail Physics Engine works with the most popular AI clients.
These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Rail Physics Engine to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client
One URL. Every client.
Activate the Connector, copy your link, and paste it into the client you already use. 4 capabilities arrive ready to run.
Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Rail Physics Engine, so you can see the experience inside your AI.
It does not authenticate your account with Rail Physics Engine. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions Rail Physics Engine owners ask.
- 01
How does the equipment type affect the calculation?
The calculation adjusts friction resistance based on whether you use a jib or a board, as they have different contact surface areas.
- 02
What is the difference between flat and kinked entry?
A flat entry assumes a continuous level surface, while a kinked entry accounts for an immediate angular change which increases initial resistance.
- 03
Can I get a full report of the rail impact?
Yes, you can use the analyze_feature_efficiency capability to get a holistic overview including approach speed, speed loss, exit speed, and momentum retention.
