AI agents call get_block_height to retrieve information from MCP Mempool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns the current block height from the Bitcoin blockchain—a read-only operation with no ability to modify data, execute code, or trigger financial transactions. It is purely informational retrieval, consistent with other Read tools on this server like get_mempool_info and get_transaction_info.
From the tool's definition Tool name 'get_block_height' and description '현재 블록 높이를 조회합니다' (retrieve current block height) indicate a query operation that retrieves blockchain data without modification or side effects.
