memos-n8n-vectorsearch-mcp

The system exposes Memos API functionalities (create, search, update, delete, upload) to AI assistants via an n8n Model Context Protocol (MCP) server. This requires careful security configuration of the n8n instance, the AI assistant, and the Memos API token to prevent unauthorized access or misuse. The 'Delete Memo' tool carries an explicit warning, emphasizing its destructive nature. All API calls rely on Bearer token authentication for Memos and the MCP server. CRITICAL RISK: The 'Memos vector search tool' workflow uses an unauthenticated 'Chat Trigger' webhook, meaning anyone with the webhook URL can interact with the AI agent and consume OpenAI tokens, potentially leading to unauthorized usage and cost. The hardcoded 'https://notes.littlepear.org/' example URL in the 'Notes vector store schedule update.json' for memo URLs must be updated to the user's Memos instance to prevent unintended data links or privacy exposure. Workflows do not use 'eval' or obvious obfuscation.
