Query live blockchain data in Claude Desktop

The BlockCypher MCP Server connects Claude Desktop directly to Bitcoin and Ethereum networks so you can inspect live on-chain metrics without leaving your chat window. Your agent uses `get_blockchain` to retrieve network health and `get_block_by_height` or `get_block_by_hash` to dig into specific blocks instantly. You don't need to keep block explorers open in twenty browser tabs. Just ask Claude to check a wallet balance via `get_address_balance` or grab full transaction histories with `get_address`, and the data feeds right into your active conversation.

Draft and broadcast transactions

The BlockCypher transaction interface lets your AI agent build, sign, and broadcast transactions across multiple chains using simple chat prompts. Claude coordinates the sequence by calling `new_transaction` to generate the raw skeleton and `send_transaction` to push the signed payload to the live network. If you are testing smart contracts, the agent deploys them with `create_eth_contract` or executes specific logic using `call_eth_contract_method`. You control the keys and signing process locally while Claude handles the heavy lifting of API formatting.

Spin up test environments and webhooks

The BlockCypher webhook and funding system gives Claude Desktop the ability to configure live event monitoring and fund test wallets on the fly. Your agent sets up real-time notifications by triggering `create_webhook` to watch specific addresses for incoming payments. For development cycles, you can instantly fund test addresses using `fund_bcy_test_address` or `fund_beth_test_address` without searching for sketchy web faucets. You get a fully functional sandbox environment managed entirely through natural language commands.
