Get all your highlighted passages from bookmarks.
AI agents call get_highlights to retrieve information from Krill To MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing highlighted passages from the user's bookmarks without creating, modifying, deleting, or executing any actions. It is a straightforward read operation with minimal risk—the worst case is unauthorized access to the user's bookmark highlights, which would be a data privacy concern rather than a destructive or systemic risk.
