Do I need my own Blockscout instance?

No, but you must provide the Base URL of the Blockscout instance you want to use, such as eth.blockscout.com.

Which AI clients can I use with this MCP?

You can use any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

How do I increase my request limits?

You can provide an API key in the configuration to access higher rate limits provided by your Blockscout instance.

Can I use this for non-Ethereum chains?

Yes, as long as the Blockscout instance you connect to supports the chain you are interested in.

Does this work with Etherscan?

This MCP specifically uses the Blockscout API, though many of the capability functions are designed to be compatible with Etherscan-style endpoints.

Can I see all the different tokens owned by a specific wallet address?

Yes. By using the list_token_balances capability with the wallet's address hash, the agent will return a comprehensive list of all ERC-20, ERC-721, and ERC-1155 tokens associated with that account.

Is it possible to check if the Blockscout explorer is fully updated with the latest chain data?

Absolutely. You can use the get_indexing_status capability to check the synchronization progress, including the indexing ratios for blocks and internal transactions.

Can I retrieve the ABI of a verified smart contract to interact with it?

Yes, for verified contracts, you can use the get_contract_abi capability. This provides the Application Binary Interface required for decoding transactions or making contract calls.

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.

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.

Real work

What teams actually run

Smart Contract Debugging

A developer asks the agent to check the gas used and status of a specific transaction hash to find out why a call failed.

Portfolio Monitoring

A user asks the agent to list all ERC-20 tokens held by a specific wallet to get a quick overview of their assets.

Contract Verification

An analyst pulls the source code and ABI of a contract to verify its logic against a known standard.

Network Health Checks

A developer checks the indexing status and block metadata to ensure the explorer is up to date.

Automate a task

Put Blockscout 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.

How to audit wallet holdings

One connector, every AI

Blockscout 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 Blockscout 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. 14 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 Blockscout, so you can see the experience inside your AI.

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