Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 14 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Manually tracking asset ownership is a nightmare of tabs and APIs.

Today, checking an address's full holdings means jumping between the native coin tracker, then finding the ERC-20 section, switching to the NFT marketplace view, and maybe running a separate API call just for governance tokens. You copy-paste addresses into five different web pages, risking data mismatch every time.

With this MCP, you ask your agent one question: 'Show me all assets at address X.' The system consolidates everything—the native balance, the list of ERC-20s, and the NFTs—and presents it in a single output. It’s an instant audit.

Using `list_token_balances` gives you a complete picture of all asset types.

Before, you'd have to run separate queries for standard tokens versus non-fungible assets. You'd get one list and then another list, forcing you to mentally merge the data points to know the true scope of holdings.

Now, running `list_token_balances` aggregates all those types into a single payload. It’s simple; it cuts out the multi-step process.

What your AI can actually do with this

Need to know what's happening on a smart contract? This MCP lets you ask complex blockchain questions using natural language. Forget switching between multiple explorer tabs; just ask your agent directly for the raw data. You can get native balances for any wallet or contract address, list every ERC-20 and NFT token an address holds in one go, and pull detailed information about specific transactions—including gas usage and decoded input data.

Want to audit a smart contract? Use this toolset to fetch verified ABIs and source code directly from the chain. It's deep on-chain analysis delivered through simple conversation. By connecting Blockscout via Vinkius, you get a single point of access to read block metadata and check indexing status for immediate verification.

Questions you might have

How do I find out if an address holds NFTs using list_token_balances? +

The list_token_balances tool covers all token types, including ERC-721s and ERC-1155s. It returns a grouped list that tells you exactly how many non-fungible tokens the address owns.

Can I get contract source code using get_contract_source_code? +

Yes, get_contract_source_code pulls the original code from the explorer. This is critical for verifying that a deployed contract matches its intended design.

What's the difference between get_account_transactions and get_account_internal_transactions? +

Use get_account_transactions to see every transaction initiated by the address. Then, use get_account_internal_transactions to trace any calls made by contracts that were called during those transactions.

Should I use get_transaction or json_rpc for raw data? +

get_transaction is best for viewing a specific, known transaction's status and gas. Use json_rpc only when you need to execute an obscure, standard Ethereum method not covered by the dedicated tools.

How do I check rate limits or increase my query allowance when using `get_account_balance`? +

You improve your rate limits by providing a dedicated API Key during setup. This key authenticates you and allows the MCP to make more requests without hitting standard usage caps. Use this if you plan on running large-scale audits or querying many addresses.

What does `get_indexing_status` tell me about the data I'm pulling? +

This tool confirms whether the Blockscout instance is fully synced with the blockchain. If the status reports 'synced,' you know that all transaction and block data up to the latest confirmed height is available for querying.

Does `get_address` give me more details than just a native coin balance? +

Yes, it provides key metadata about an address. Beyond the current native balance, you get essential data points like its associated ENS name and the total count of transactions linked to that wallet.

If a specific tool doesn't exist, can I still query custom methods using `json_rpc`? +

Absolutely. The json_rpc tool lets you execute any standard Ethereum JSON-RPC 2.0 method directly. This gives you access to niche or highly specialized data calls not covered by the predefined tools.

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

Yes. By using the list_token_balances tool 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 tool 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 tool. This provides the Application Binary Interface required for decoding transactions or making contract calls.
