Retrieve a specific note by ULID or filename
AI agents call get_note to retrieve information from Notes MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches an existing note by identifier without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius if misused by an AI agent—worst case, it accesses unintended note content.
From the tool's definition Tool name 'get_note' and description 'Retrieve a specific note' indicates data retrieval with no modifications or side effects.
