getAllNotes
AI agents call getAllNotes to retrieve information from Simple TypeScript 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/queries data (all notes) without creating, modifying, deleting, or executing external operations. No side effects are implied by its name or the server's purpose (note-taking CRUD). It falls clearly into the Read category with low severity.
From the tool's definition Tool name 'getAllNotes' indicates a retrieval operation with no side effects. The sibling context shows CRUD operations (createNote, deleteNote, getNote, updateNote), where getAllNotes logically retrieves all notes without modification.
