Blastscan MCP. Analyze token movements & contract state.

Blastscan connects your agent straight into the Blast blockchain state. You'll use it to check balances, track tokens across multiple standards, and deep-dive into contract logic right from your client.

Balances & Supply Tracking:
You can check the current native Ether balance for a single address using get_ether_balance, or you'll get the balances for several addresses at once with get_ether_balance_multi. For ERC20 tokens, use get_erc20_token_balance to see an account’s holdings in a specific token contract. To track overall market movement, it provides the last known ETH price via get_eth_price, and calculates both the total circulating supply of Ether (get_eth_supply) and the total circulating supply for any ERC20 contract using get_erc20_token_supply.

Tracing Token Movements:
It tracks all major token standards. You'll list standard ERC20 transfers with get_erc20_transfers, get records of unique NFT movements (ERC721) through get_erc721_transfers, and track multi-token events using get_erc1155_transfers. Beyond specific transfer types, you can fetch general event logs emitted from the chain for an address or a range using get_logs.

Transaction History & Status:
You get a standard transaction history with get_normal_transactions, but you'll also find detailed records of internal transactions that happen through an address’s activity via get_internal_transactions. When you need to verify a specific movement, it retrieves all metadata and details for a given hash using proxy_eth_gettransactionbyhash or fetches the full receipt—including gas used and event logs—for a completed transaction with proxy_eth_gettransactionreceipt.

You can check if any transaction hash successfully processed using get_transaction_receipt_status, or determine if a smart contract interaction succeeded or failed outright via get_transaction_status.

Contract Logic & Code Inspection:
Want to know how a contract works? Use get_contract_source_code to pull the actual, human-readable source code for verified contracts. You can also retrieve the Application Binary Interface (ABI) needed to interact with a contract's logic using get_contract_abi. For deeper inspection, it checks and returns the raw bytecode stored at an address via proxy_eth_getcode, or reads the value of a specific storage slot key within a contract using proxy_eth_getstorageat.

Network State & Gas Calculations:
It gives you real-time network metrics. You'll find the current latest block number with proxy_eth_blocknumber. If you need to know how long it is until the next block, use get_block_countdown. It calculates the estimated gas needed for any action using proxy_eth_estimategas, and tells you the recommended base price of gas on the network via proxy_eth_gasprice.

For historical data, you can find all data inside a specific block number with proxy_eth_getblockbynumber, or get general information about a past block using proxy_eth_getblockbynumber.

Advanced Querying:
For transaction details, it allows you to simulate calling a contract function without actually spending gas or changing the state through proxy_eth_call. You can also check which blocks were mined by an address over time with get_mined_blocks, and get general data about any specific historical block number using proxy_eth_getblockbynumber.
