Perplexity

Pipe live block heights into terminal scripts

`eth_block_number` and `btc_getblockcount` feed real-time blockchain height data directly into your terminal-based agent. Claude Code runs these queries headlessly, allowing you to build shell scripts that trigger actions when new blocks are mined. You get low-latency chain monitoring without heavy local daemon processes. The CLI agent pipes this block data to other terminal utilities or writes it to local log files. This setup is perfect for lightweight cron jobs or DevOps monitoring scripts.

Broadcast raw transactions via Claude Code

`btc_sendrawtransaction` and `sol_send_transaction` let your terminal agent broadcast pre-signed transaction payloads straight to the network. You generate the transaction offline, pipe the signed hex to Claude Code, and let it handle transmission and receipt verification. You keep your private keys strictly offline while maintaining a fast broadcast pipeline. The agent monitors the transaction hash on-chain and returns a non-zero exit code if the broadcast fails. This makes it easy to integrate transaction dispatching into automated CI/CD pipelines.

Analyze Bitcoin PSBTs inside this MCP Server

`btc_analyzepsbt` and `btc_createpsbt` expose raw Bitcoin transaction mechanics to your command-line workspace. Claude Code decodes the partially signed transactions, verifies the input values, and identifies missing signatures. You get a clear, human-readable breakdown of complex multisig payloads before broadcasting. The agent automates the signing coordination by tracking which keys have signed the payload. You avoid manual parsing errors and speed up multisig wallet operations.
