This MCP server implements the Zettelkasten knowledge management methodology, focusing on atomic notes that are interconnected to form a knowledge graph. It allows users to create different note types—such as fleeting, literature, permanent, and structure notes—and establish semantic links like references, support, contradict, and related. The system offers features like bidirectional linking, tagging, markdown editing, and searching capabilities, all stored in Markdown with an index for efficient traversal. Integrated with Claude and MCP clients, it supports AI-assisted knowledge exploration, synthesis, and discovery, making it an effective tool for researchers, students, and knowledge workers to organize and analyze complex information networks.
