Script headless AntChain deployments from Claude Code

Claude Code brings blockchain administration directly to your terminal session, running `deploy_contract` to push compiled hex bytecode. It pushes your contracts to the network without needing a heavy GUI or web browser. This MCP Server allows you to pipe contract deployment outputs directly into shell scripts. You can run a deployment, grab the address, and immediately kick off a local test suite using that live address.

Run instant terminal-based ledger diagnostics

When a transaction fails in your CI/CD pipeline, Claude Code calls `query_transaction` to pull the exact execution receipt. It dumps the gas usage and failure state directly into your terminal output. You can run `query_block` to inspect block times and transaction density when debugging network latency. It keeps your terminal-focused workflow fast and distraction-free.

Query accounts and balances in headless environments

Managing gas wallets for automated scripts is simple when you check balances using `query_account_balance`. Claude Code uses this data to verify your deployer accounts before running scheduled tasks. If you need to audit account permissions, the agent calls `query_account` to check the ledger state. It gives you raw, clean JSON data that you can pipe into other command-line tools.
