Returns the total number of bitcoins that have been mined
AI agents call get_total_bitcoins to retrieve information from MCP Blockchain Query Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries blockchain statistics and returns read-only information. It retrieves a single aggregate metric (total BTC mined) without creating, modifying, deleting, or executing any operations. No financial transactions are performed, and the blast radius of misuse is minimal—an AI agent could only receive incorrect or irrelevant blockchain data.
From the tool's definition Tool name 'get_total_bitcoins' and description 'Returns the total number of bitcoins that have been mined' indicate a pure data retrieval operation with no side effects.
