Connect Cronoscan Cronos Block Explorer to your AI
Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Query on-chain transactions and contract code through your AI client.

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.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Cronoscan 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 Cronoscan, so you can see the experience inside your AI.
It does not authenticate your account with Cronoscan. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Yes, the MCP includes capabilities to retrieve ERC721 token transfer events by address.
- 04
Does this support Ethereum-style calls?
Yes, it includes proxy capabilities for standard calls like eth_call and eth_estimateGas.
- 05
Can I check multiple balances at once?
Yes, the get_balance_multi capability allows you to check CRO balances for multiple addresses in one request.
- 06
Can I check the CRO balance of multiple wallet addresses in a single request?
Yes! Use the get_balance_multi capability by providing a comma-separated list of addresses. The AI will return the current balance for each address in the list.
- 07
How do I retrieve the source code of a verified smart contract on Cronos?
You can use the get_source_code capability with the contract's address. If the contract is verified on Cronoscan, the AI will fetch the source code, compiler version, and other optimization details.
