AI agents call get_notes to retrieve information from MCP Bear 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 notes without creating, modifying, deleting, or executing any operations. It has no side effects and presents minimal risk—the worst outcome is information disclosure limited to the user's own notes within their Bear application.
From the tool's definition Tool name 'get_notes' and description 'Get all notes from Bear' indicate a retrieval operation. The server description confirms this tool operates via SQLite for 'data retrieval' (contrasted with 'x-callback-url for modifications').
