Read content of an existing Obsidian note
AI agents call read_obsidian_note to retrieve information from Obsidian Translation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation to retrieve note content from Obsidian. It does not create, modify, delete, or execute any actions — only reads existing data. The low severity reflects minimal risk: an AI agent misusing this tool could only access information already stored in Obsidian notes, with no capability to alter state or cause harm beyond potential unauthorized information disclosure.
From the tool's definition Tool name is 'read_obsidian_note' and description states 'Read content of an existing Obsidian note' — explicitly a retrieval operation with no modification or side effects.
