AI agents call subscribe_live_chart 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 retrieves and streams real-time chart data from the mempool.space API. It performs no write operations, does not execute arbitrary code, does not delete data, and has no financial impact. Subscribing to a data feed is fundamentally a read operation. The severity is low because misuse would only expose publicly available Bitcoin network statistics without side effects.
From the tool's definition subscribe_live_chart subscribes to real-time 2-hour chart data. The description and name indicate passive data retrieval/streaming of chart information with no modification, creation, or deletion of data.
