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.

V8 Isolate01

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.

Kill Switch02

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.

FinOps per User03

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.

Automate a task

Put TzKT to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

TzKT 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.

Building your own app? The connector is yours to use.

You don't need a client to put TzKT 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.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 25 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 TzKT, so you can see the experience inside your AI.

It does not authenticate your account with TzKT. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions TzKT owners ask.

  • 01

    Do I need a TzKT API key?

    It is optional. You can use the MCP without one, but providing a key allows for higher rate limits.

  • 02

    Which networks are supported?

    The MCP supports Tezos Mainnet, Ghostnet, and Shadownet.

  • 03

    Can I use this with Cursor?

    Yes, you can connect this MCP to Cursor or any other MCP-compatible client.

  • 04

    How do I check smart contract code?

    You can ask your agent to use the get_contract_code capability to pull Michelson or Micheline code.

  • 05

    Is the data real-time?

    Yes, the MCP connects to the TzKT indexer to provide live on-chain data.

  • 06

    Can I see how an account's balance has changed over time?

    Yes! Use the get_account_balance_history capability with the account address. It will return a historical record of balance changes for that specific Tezos address.

  • 07

    How do I check the current state or storage of a smart contract?

    You can use the get_contract_storage capability by providing the contract's KT1 address. This will retrieve the current data stored in the contract's state.

  • 08

    Is it possible to list transactions for a specific sender or target?

    Absolutely. Use the list_transactions capability and apply filters like sender or target to narrow down the results to specific addresses or interaction flows.
