Zettelkasten MCP Server A Model Context Protocol (MCP) server that implements the Zettelkasten knowledge management methodology, allowing you to create, link, explore and synthesize atomic notes through Claude and other MCP-compatible clients. What is Zettelkasten? The Zettelkasten method is a knowledge management system developed by German sociologist Niklas Luhmann, who used it to produce over 70 books and hundreds of articles. It consists of three core principles: Atomicity: Each note contains exactly one idea, making it a discrete unit of knowledge Connectivity: Notes are linked together to create a network of knowledge, with meaningful relationships between ideas Emergence: As the network grows, new patterns and insights emerge that weren't obvious when the individual notes were created What makes the Zettelkasten approach powerful is how it enables exploration in multiple ways: Vertical exploration: dive deeper into specific topics by following connections within a subject area. Horizontal exploration: discover unexpected relationships between different fields by traversing links that cross domains.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
