How to Use the Cronoscan (Cronos Block Explorer) MCP in Claude Code

Q: How do I install the Cronoscan (Cronos Block Explorer) server in Claude Code?

Run claude mcp add --transport http cronoscan -- in your terminal. This registers the server in your /.claude.json file.

Q: How does Claude Code handle transaction receipt checks via Cronoscan (Cronos Block Explorer)?

Claude Code calls gettxreceiptstatus with the transaction hash you provide. It immediately parses the status code and outputs whether the transaction succeeded or failed.

Q: Can I query ERC-20 token transfers from the command line?

Yes. Use Claude Code to call gettokentx to fetch transfer events for any token contract address and filter them directly in your shell.

Monitor Cronos network gas, track block rewards, and query contract ABIs directly from your terminal using Claude Code.

Perplexity

Run terminal-based contract audits using this MCP Server

This MCP Server exposes `get_source_code` to pull verified Solidity code directly into your terminal session. Claude Code reads the code, checks the ABI with `get_abi`, and runs static analysis to find vulnerabilities. You can pipe this output straight into local security tools or save the audit reports to your repository. It replaces manual web searches with direct terminal commands.

Monitor gas prices and estimate deployment costs

The `proxy_eth_gas_price` tool fetches the current gas price on the Cronos network directly to your CLI. Claude Code uses this value alongside `proxy_eth_estimate_gas` to calculate the exact CRO cost of running a transaction or deploying a contract. This allows you to write shell scripts that check gas levels before running automated migration scripts. You can set thresholds to avoid deploying during high-congestion periods.

Query block rewards and chain supply metrics

The `get_block_reward` tool retrieves the validator payout and block details for any specific block height on Cronos. Claude Code combines this data with `get_eth_supply` to report on the total circulating supply of CRO. You can run quick terminal queries to check chain inflation or validator performance without opening a browser. The raw JSON output is formatted instantly in your console.
