Get notes with optional filters
AI agents call get_notes to retrieve information from Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves notes (presumably from Google Keep based on the server description) and applies optional filters for search/retrieval purposes. It does not create, modify, delete, or execute any operations—it only reads and returns data. The potential blast radius is minimal, as misuse would only expose information the agent already has access to read.
From the tool's definition Tool name 'get_notes' and description 'Get notes with optional filters' indicate a retrieval operation with no side effects. The verb 'get' is characteristic of read operations that query existing data.
