A Model Context Protocol (MCP) server implementing the Zettelkasten knowledge management methodology.
The Zettelkasten MCP Server is a digital implementation of the Zettelkasten method, a knowledge management system developed by Niklas Luhmann. It allows users to create, link, explore, and synthesize atomic notes through Claude and other MCP-compatible clients. The system is based on three core principles: atomicity, connectivity, and emergence, enabling users to dive deeper into specific topics or discover unexpected relationships across different fields. The server supports various note types and link types, creating a rich, multi-dimensional knowledge graph. It uses a dual storage architecture with Markdown files as the source of truth and an SQLite database for efficient querying and search operations. The server integrates with Claude for AI-assisted knowledge management and offers a synchronous operation model for simplified architecture.
Features
- Create atomic notes with unique timestamp-based IDs
- Link notes bidirectionally to build a knowledge graph
- Tag notes for categorical organization
- Search notes by content, tags, or links
- Use markdown format for human readability and editing
