IVGraphAI agents and MCP
AI agents can now read and edit a Notion workspace through MCP, the Model Context Protocol, and a language model can keep a personal wiki up to date from your sources. These guides show how to set that up and what to watch out for. They cover the official Notion MCP server and its setup for Claude, ChatGPT, Codex and Cursor, five Claude Code workflows for a second brain that maintains itself, and Andrej Karpathy's LLM wiki pattern with a Notion version of it. The GraphRAG guide explains when a knowledge graph gives a model better context than vector search.
An agent that writes to your workspace adds pages and links faster than you can review them in a list. A graph view helps here: IVGraph shows a Notion workspace as one connected map, so you can check what the agent added, what it linked and which pages it left disconnected.
