ZettelkastenSpace MCP Server
An AI-enhanced Zettelkasten note-taking app with an MCP integration giving Claude Desktop direct, permission-scoped access to a user's own notes - finding connections, summarizing learning progress, and surfacing research gaps. Use when you keep a networked, tag-linked personal knowledge base and want Claude to answer questions grounded in that specific content. Requires a zettelkasten.space account, not a local-only tool.
What it does
Zettelkasten Space is a personal knowledge-management web app (at zettelkasten.space) built on the Zettelkasten note-linking method, with a Model Context Protocol integration that gives Claude Desktop direct, context-aware access to a user's own notes. Rather than a generic AI chat that knows nothing about your notes, the MCP integration lets Claude answer questions grounded in the user's actual knowledge base - the source gives worked examples like asking Claude to find connections between two topic areas across a user's notes, summarize how a subject's understanding evolved over months of notes, identify unexplored gaps in a topic collection, or suggest how a new piece of research relates to existing notes.
The MCP implementation's stated technical characteristics are secure authentication via rotating tokens with granular permissions, real-time sync so the AI context stays current with the knowledge base, optimized performance through caching and batch operations, and privacy controls letting the user decide exactly what the AI can access. On the privacy/security side specifically: the user retains full control over what data the AI can see, permissions can include or exclude specific notes by tag or rule, tokens rotate automatically, and there's a logged audit trail of AI interactions with the data.
Getting started is a three-step flow: create a knowledge base (sign up at the site, add notes, apply tags and connections), connect to Claude Desktop (generate a secure token from the dashboard's MCP Integration panel and add it to Claude Desktop's configuration), then use natural-language requests to ask Claude about the connected notes. The underlying stack is React, TypeScript, Python, FastAPI, PostgreSQL, Supabase, Vercel, and Render, and the product credits its conceptual lineage to Niklas Luhmann's Zettelkasten method, Andy Matuschak's writing on note-taking, and Tiago Forte's Building a Second Brain.
When to use - and when NOT to
Use this when you already keep (or want to start keeping) a networked, tag-linked personal knowledge base and want Claude to answer questions, find connections, or surface gaps grounded in that specific content, rather than generic knowledge. It requires an account on the hosted zettelkasten.space service and a note collection large enough to make cross-note discovery meaningful - it isn't a local-only or self-hosted note tool, and the source doesn't publish a specific MCP client-configuration snippet, only that a token is generated and copied into Claude Desktop's settings. The source also frames it as useful for sharing curated knowledge with colleagues or a team, not only solo use, since notes can be selectively exposed rather than kept purely private.
Capabilities
Answers natural-language questions grounded in the user's own connected notes: finding cross-topic connections, summarizing how understanding of a subject evolved over time, identifying gaps in a topic collection, and relating new material to existing notes - all scoped by the user's own tag/rule-based access permissions.
How to install
Sign up at zettelkasten.space, generate a secure token from the dashboard's MCP Integration panel, and add that token to Claude Desktop's MCP configuration (the source describes this as a one-click/token-copy setup rather than publishing a specific JSON snippet). Tokens rotate automatically for security, and access can be scoped by tag or rule before connecting. Further reference material is split across a Project Overview document, a dedicated MCP Integration guide, and a Technical Guide for developers. The project's own License & Attribution note does not name a specific license family - it states only that the project is built with respect for user privacy, data ownership, and the open-source community.
Who it's for
Researchers doing literature reviews and thesis work, knowledge workers building project documentation and institutional memory, and lifelong learners tracking skill development and reading notes - anyone who wants Claude to reason over their own accumulated notes instead of starting from a blank context every conversation.
