Zettelkasten Space is an MCP-enabled personal knowledge management platform that connects notes into a living, networked knowledge graph. By integrating the Model Context Protocol with Claude Desktop, it provides context-aware AI that can reason over your entire knowledge base, enabling natural language queries, intelligent discovery, and dynamic synthesis across notes. The MCP integration supports secure authentication with rotating tokens and granular permissions, ensuring you control exactly what the AI can access. Real-time synchronization keeps AI context updated as you add or modify notes, while intelligent caching and batch operations optimize performance. Privacy controls give users full ownership of their data, with the ability to include or exclude notes via tags or rules and to audit AI interactions via a complete activity log. The design emphasizes cloud-plus-local capabilities, mobile readiness, and automatic linking of notes to reveal unexpected connections, helping researchers, professionals, and lifelong learners accelerate insight generation.
