AI agents call kibela_get_note_content 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 note content without side effects. It is a read-only operation that queries and returns data from Kibela. No data is created, modified, deleted, or executed. The low severity reflects minimal risk: even if an AI agent calls this repeatedly or retrieves sensitive notes, the worst outcome is information disclosure, not irreversible damage or financial impact.
From the tool's definition Tool description states 'Get note content by note ID' - a retrieval operation with no modification or deletion. The server description also lists 'retrieval' as a primary capability alongside search and access.
