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.

Cursor's Agent mode turns AntChain into an in-editor superpower. Ask Cursor to generate code using live data from AntChain and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

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 Cursor 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 Cursor with the AntChain MCP Server

Cursor AI Code Editor provides unique advantages when paired with AntChain through the Model Context Protocol.

Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context

Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards

MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment

VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

AntChain + Cursor Use Cases

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

Code generation with live data: ask Cursor to generate a security report module using live DNS and subdomain data fetched through MCP

Automated documentation: have Cursor query your API's tool schemas and generate TypeScript interfaces or OpenAPI specs automatically

Infrastructure-as-code: Cursor can fetch domain configurations and generate corresponding Terraform or CloudFormation templates

Test scaffolding: ask Cursor to pull real API responses via MCP and generate unit test fixtures from actual data

AntChain MCP Tools for Cursor (10)

AntChain + Cursor FAQ

Common questions about integrating AntChain MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
