Perplexity

Run terminal-based wallet audits

The `get_transactions` tool lists historical transactions, block heights, and timestamps for any wallet address on a supported chain. You can pipe this raw terminal output directly into grep or jq to filter for specific actions. Combine this with `get_token_transfers` to track exact sender and receiver addresses for individual tokens. No browser, no block explorer, just fast command-line debugging.

Monitor indexer status via CLI with this MCP Server

This MCP Server uses `get_chains_status` to report current block height lag and API availability across all supported networks. You can run this check inside an automated cron job or a bash script to monitor node health. If a network starts lagging, your terminal script can catch it immediately. You get the raw sync status without writing custom web3 provider connections.

Inspect block details on the fly

The `get_block_details` tool resolves parent hashes, timestamps, and transaction counts for any block height you specify. When debugging a transaction failure, you can query the block directly from your terminal to inspect the environment. You can verify supported features on any network using `list_supported_chains` before running your queries. It gives you a clean list of chain IDs and capabilities in seconds.
