How do I get my AntChain Access Key and Secret Key?

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.

What's the difference between querying a block and querying a transaction?

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.

Can I deploy smart contracts through this MCP server?

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.

About AntChain MCP Server

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.

AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use AntChain tools. Connect 10 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.

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

The AntChain MCP Server exposes 10 tools through the Vinkius. Connect it to AutoGen in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use AutoGen with the AntChain MCP Server

AutoGen provides unique advantages when paired with AntChain through the Model Context Protocol.

Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use AntChain tools to solve complex tasks

Role-based architecture lets you assign AntChain tool access to specific agents. a data analyst queries while a reviewer validates

Human-in-the-loop support: agents can pause for human approval before executing sensitive AntChain tool calls

Code execution sandbox: AutoGen agents can write and run code that processes AntChain tool responses in an isolated environment

AntChain + AutoGen Use Cases

Practical scenarios where AutoGen combined with the AntChain MCP Server delivers measurable value.

Collaborative analysis: one agent queries AntChain while another validates results and a third generates the final report

Automated review pipelines: a researcher agent fetches data from AntChain, a critic agent evaluates quality, and a writer produces the output

Interactive planning: agents negotiate task allocation using AntChain data to make informed decisions about resource distribution

Code generation with live data: an AutoGen coder agent writes scripts that process AntChain responses in a sandboxed execution environment

AntChain + AutoGen FAQ

Common questions about integrating AntChain MCP Server with AutoGen.

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call AntChain tools during their conversation turns.

Can different agents have different MCP tool access?

Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
