You are signing in to the Citadel MCP server, a personal knowledge management tool that gives AI assistants such as Claude a long-term memory.
Citadel stores your notes, project context and todos, organised into rooms. Once signed in, you can manage them in your browser, and your AI assistant can read and update them through the Model Context Protocol (MCP), so it remembers your projects from one conversation to the next. Citadel is an independent project and is not affiliated with any other company.
