Read blockchain state in Claude Desktop

Stop jumping between your browser and your chat. You can use `get_block` or `get_transaction` to pull live data straight into your workspace. This MCP Server handles the heavy lifting by talking to the chain for you. Claude gets the raw response, so you spend less time digging through explorers.

Analyze smart contracts with Claude Desktop

Grab source code or ABIs on the fly. Simply trigger `get_contract_source_code` or `get_contract_abi` to view the logic behind any address. Your agent parses the bytecode and explains exactly what the contract does. No more manual copying and pasting from block explorers.

Track wallet activity in Claude Desktop

Monitor any address by calling `get_account_transactions` or `get_account_internal_transactions`. You get a clean list of movements without the usual noise. It works for token balances too. Just run `list_token_balances` to see what's actually sitting in a wallet at this second.
