Built-in capabilities (10)

deploy_contract

Requires the contract bytecode (compiled bytecode in hex format) and optionally the ABI (Application Binary Interface) for interaction. Returns the deployed contract address and deployment transaction details. The contract will be available under the specified name. Deploy a smart contract on AntChain

get_chain_list

Returns chain IDs, names, creation dates, status, and basic configuration. Use this to discover which blockchains you have access to before performing operations. List all available blockchain networks in your AntChain account

invoke_contract

Provide the contract name, method name, and any required arguments. Returns the execution result including return values, gas consumption, and transaction status. Use this to interact with deployed contracts. Invoke a smart contract method on AntChain

query_account

Use this to inspect account state and activity. Query account information on AntChain

query_account_balance

Returns the available balance and any locked/pending amounts. Useful for checking if an account has sufficient funds for transactions or contract interactions. Query account balance on AntChain

query_block

Returns block metadata including timestamp, transaction count, hash, and previous block reference. Use either blockHeight or blockHash to identify the block. Query block details from an AntChain blockchain

query_contract

Useful for inspecting contract configuration before invocation. Query smart contract information on AntChain

query_latest_transactions

Useful for monitoring network activity, auditing recent transactions, or getting a snapshot of current blockchain operations. Returns a list of recent transactions with their status and metadata. Query the latest transactions on an AntChain blockchain

query_network_info

Useful for monitoring blockchain infrastructure health. Query blockchain network information on AntChain

query_transaction

Returns transaction status, sender, receiver, gas used, block inclusion, and execution result. Useful for verifying transaction finality and inspecting transaction details. Query a transaction on AntChain

What this connector unlocks

Connect your AntChain (蚂蚁链) BaaS platform account to any AI agent and gain complete visibility and control over your enterprise blockchain operations through natural conversation. AntChain is Alibaba Group's blockchain-as-a-service platform, designed for consortium chains, enterprise smart contracts, and secure decentralized applications.

What you can do

Block Exploration — Query detailed information about any block by height or hash, including transaction counts and timestamps
Transaction Tracking — Inspect individual transactions by hash or ID, verifying status, gas consumption, and execution results
Smart Contract Management — Deploy new contracts, invoke contract methods, and query contract metadata and ABIs
Account Inspection — Check account balances, nonce values, and metadata for any wallet address on the chain
Network Monitoring — View network topology, node status, consensus state, and chain health metrics
Chain Discovery — List all blockchain networks available to your organization with their configurations
Recent Activity — Monitor the latest transactions and network activity in real-time

How it works

1. Subscribe to this server
2. Enter your AntChain Access Key and Secret Key
3. Start querying your blockchain networks from Claude, Cursor, or any MCP-compatible client

Your AI agent becomes your blockchain operations center, handling contract deployment, transaction verification, and network monitoring without complex CLI tools.

Who is this for?

Blockchain Developers — Deploy and interact with smart contracts directly from your IDE using natural language
Enterprise Ops — Monitor consortium chain health, node status, and network metrics through conversational queries
Auditors & Compliance — Verify transaction finality, inspect account balances, and audit contract executions
Product Teams — Query blockchain data for dApps without writing boilerplate API integration code

Frequently asked questions

Log in to the AntChain BaaS console, navigate to the API Management or Developer Center section, and create a new API credential pair. You'll receive an Access Key (public identifier) and a Secret Key (used for HMAC-SHA256 signature generation). The Secret Key is shown only once — save it immediately. These credentials authenticate all your API requests.

A block query returns information about the container itself — block height, hash, timestamp, transaction count, and the previous block hash. A transaction query returns details about a specific operation within a block — sender/receiver addresses, gas used, execution status, return values, and whether the transaction succeeded or reverted. Use blocks to explore the chain structure, and transactions to verify individual operations.

Yes! Use the deploy_contract tool to upload and deploy compiled smart contract bytecode to your AntChain network. You'll need the contract bytecode (in hex format), a name for the contract, and optionally the ABI for future interactions. After deployment, you can invoke contract methods using the invoke_contract tool. Make sure your account has sufficient permissions and balance for deployment.
