AI agents call kibela_get_note_from_path to retrieve information from MCP Kibela without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing note content without creating, modifying, or deleting data. It is a read-only query operation with no side effects, making it a classic Read category tool. Severity is low because retrieving information poses minimal risk unless the notes contain highly sensitive data, but that is a data-sensitivity issue rather than a tool-capability issue.
From the tool's definition Tool description states 'Get note content by note path' — a retrieval operation with no modification or deletion. Server description confirms this is part of 'search and access information' capabilities.
