Compact summary of recent notes by key (snippets + top tags) to prepend as system context.
AI agents call index-bootstrap-summary to retrieve information from MCP Index Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and summarizes note data for contextual purposes. It performs read-only operations (fetching snippets and tags) without creating, modifying, deleting, or executing anything. The low severity reflects minimal blast radius - a summary provided as context cannot cause harm even if misused by an agent.
From the tool's definition Tool description states it provides a 'compact summary of recent notes by key (snippets + top tags)' - purely retrieval and aggregation of existing data with no modification, deletion, or execution capabilities.
