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. That is what the zettelkasten mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
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:
The server publishes 14 tools. What each one is for:
zk_create_note — Create a new note with a title, content, and optional tagszk_get_note — Retrieve a specific note by ID or titlezk_update_note — Update an existing note's content or metadatazk_delete_note — Delete a notezk_create_link — Create links between noteszk_remove_link — Remove links between noteszk_search_notes — Search for notes by content, tags, or linkszk_get_linked_notes — Find notes linked to a specific notezk_get_all_tags — List all tags in the systemzk_find_similar_notes — Find notes similar to a given notezk_find_central_notes — Find notes with the most connectionszk_find_orphaned_notes — Find notes with no connectionsSetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Configuration is passed through the environment: ZETTELKASTEN_NOTES_DIR, ZETTELKASTEN_DATABASE_PATH, ZETTELKASTEN_LOG_LEVEL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Zettelkasten's toolset — zk_create_note, zk_get_note, zk_update_note and 11 more — is a fair guide to whether it matches your workflow. It is maintained by entanglr; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
Issue tracking at the speed of conversation — Linear's official hosted server with OAuth and zero install.
Search and read your Drive — Docs, Sheets and files become context your assistant can actually use.
Your assistant inside the workspace — read channels, search history, post messages and tame the noise.
Metabase ships its own MCP endpoint — search your BI content, build and run queries, and save questions and dashboards without leaving the chat.
Stop letting your assistant hallucinate n8n node parameters — this server hands it the real schemas, templates and validation.
