Perplexity

Headless block inspection with Claude Code

Run `get_block` through your terminal to retrieve specific block details. Claude Code pipes this data directly into your scripts or logs. This lets you automate data extraction for CI/CD pipelines. You get the block metadata without a browser, keeping your workflow strictly in the shell.

Retrieve token data via this MCP Server

Use `get_erc20_token_address` to check balances for specific assets. Claude Code executes this as part of a larger script to verify deployment results. It removes the need for manual API calls or web-based lookups. You get the balance as a simple output string ready for your next command.

Streamline chain stats into your terminal

Invoke `get_blockchain_stats` to monitor network conditions from the command line. Claude Code parses the output so you can trigger alerts based on block time or fees. This is ideal for SRE tasks where you need to watch chain health. The agent handles the query and feeds the output into your existing diagnostic tools.
