Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.
Your AI does the work. We keep it safe and sound.
No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.
Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

Each Connector runs inside its own sealed environment.
Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.
One switch stops every agent. Instantly.
One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.
Spending limits that pause instead of surprise.
Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.
Three controls, built into the layer your AI connects through.
Curated set · 4 capabilities
We ship only the actions that matter.
01-04
4 capabilities in this set.
Part of 4 available through Transition Metal Chemistry.
- 01
Determine geometry and splitting
This capability identifies the most likely molecular geometry and the specific nature of the crystal field splitting.
- 02
Get electron configuration
Use this to find the exact d-electron count for a specific metal and its oxidation state.
- 03
Predict magnetic properties
This capability determines if a complex is paramagnetic or diamagnetic and calculates the magnetic moment.
- 04
Predict optical properties
This capability predicts the observed color of a complex based on its electronic transitions.
Real work
What teams actually run
Predicting Complex Color
Use the optical capabilities to determine what color a specific metal complex will appear in a lab setting.
Analyzing Magnetism
Determine if a new coordination compound will be paramagnetic or diamagnetic.
Geometry Verification
Check if a specific metal configuration will result in a Jahn-Teller distortion.
Oxidation State Analysis
Quickly find d-electron counts for various metal ions and oxidation states.
One connector, every AI
Transition Metal Chemistry 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 Transition Metal Chemistry 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.

Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Transition Metal Chemistry, so you can see the experience inside your AI.
It does not authenticate your account with Transition Metal Chemistry. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
