Manage AntChain assets in Claude Desktop

Deploy smart contracts by providing bytecode and ABI details directly to your chat interface. You'll use `deploy_contract` to push code to the chain and see deployment addresses instantly. This MCP Server handles the heavy lifting for your project. Your agent executes `invoke_contract` to run methods, letting you test business logic without leaving the app.

Audit AntChain data from your chat

Keep an eye on network health by running `query_network_info` or `query_block` through your agent. You'll grab specific hash data or transaction counts from any block height. Check account statuses using `query_account` and `query_account_balance`. It's the fastest way to confirm funds before firing off a transaction.

Track AntChain activity in real-time

Monitor the latest ledger movements by calling `query_latest_transactions`. You'll see status updates and metadata for recent network events without switching tabs. Verify specific operations with `query_transaction`. It confirms finality and gas usage, ensuring you have the full picture of your blockchain interactions.
