Overview

Description from the maker (original English)

Build mind maps, kanban boards and whiteboards in your TabTree account, team spaces included.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Other
  • You need to fill in: TABTREE_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: TABTREE_API_KEY, TABTREE_DIR

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • TABTREE_API_KEY secret required env
    Your TabTree connector key: create it in TabTree, Settings → Account → Claude connector (it starts with tt_live_). Claude reads and builds maps and kanban boards in your account — and in the team spa…
  • TABTREE_DIR env

Common questions

Is TabTree safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: TABTREE_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.22.0) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

TabTree

Mind maps, kanban boards and whiteboards — one document, many views, in your account.

Live demo — no signup · tabtree.app · Templates · Claude connector


What it is

TabTree is a mind-mapping, kanban and whiteboard app at tabtree.app. One document reads several ways: mind map, kanban board, Gantt chart, calendar, page of notes, spreadsheet or full-screen presentation. Switch views; nothing is converted and nothing is lost.

Your maps follow your accountSign in on your laptop or your phone and your library is there.
Team spacesInvite people into a space: shared maps and boards, live presence, comments, a daily digest.
TemplatesBusiness Model Canvas, Lean Canvas, OKRs, roadmaps, agent specs… browse them
It leaves the buildingPNG posts, carousel PDFs, MP4 flythroughs, or a shared page anyone can read.
Claude works in itThe connector below lets Claude read your library and build maps, boards and kanbans in it.

This repository

TabTree itself is a commercial product and its source is not published here. This repository is the public face of it, and it holds four things that are useful on their own:

  • [`mcp/`](mcp/) — the full source of the Claude connector, free to use, copy, redistribute and modify (its own licence, no attribution required), and the same code published to npm as tabtree-mcp.
  • [`plugins/tabtree/`](plugins/tabtree/) — the Claude Code plugin: it ties a coding session to one card of a board (your commits land on it), ships the connector, and adds a facilitation skill that ends in a real document. See Claude Code plugin below.
  • [`templates/`](templates/) — template outlines in plain Markdown, each with a link that opens it live. Paste them into TabTree, or into any outliner.
  • [`screenshots/`](screenshots/) — rendered by the real app, not mocked up.

To see the app itself, try the demo — it runs in your browser, with nothing to install and no signup.

Claude connector

Let Claude read your TabTree library and turn a conversation, a transcript or a spec into a real mind map, kanban board or whiteboard — in your account, on every device, and in the team spaces you belong to.

1. Get your connector key. In TabTree: ⚙️ Settings → Account → Claude connector → *Create a connector key*. It is shown once and starts with tt_live_.

2. Claude Desktop — double-click. Download TabTree-Connector.mcpb (or from tabtree.app/connector) and double-click it. Claude Desktop ships its own Node and asks for your key on its install screen.

No install — claude.ai, ChatGPT, Cursor: connect by address, https://tabtree.app/mcp. The app opens a TabTree page where you sign in and press Allow: no key to copy. In claude.ai: Settings → Connectors → Add custom connector, then paste the address.

Claude Code, or any MCP client:

claude mcp add tabtree --scope user -e TABTREE_API_KEY="tt_live_…" -- npx -y tabtree-mcp

Or in your client's config:

{

"mcpServers": { "tabtree": { "command": "npx", "args": ["-y", "tabtree-mcp"], "env": { "TABTREE_API_KEY": "tt_live_…" } } } }

Fourteen tools: list_maps, read_map, search_maps, create_mindmap, plant_project (a brief becomes a tree — roots, branches, birds), create_kanban, create_board (with your own images, and tables), plan_system (a whole system from a brief, built after review), propose_changes, harvest, fill_knowledge, card_prompt, deliver_card, and board_numbers (a kanban's burnup, what is blocking, cycle time and forecast — the numbers of TabTree's dashboard). The connector never overwrites or deletes a map. Safe changes to an existing map (add a card, move it, tick it, assign it, date it, comment on it) are applied by TabTree itself while it is open, and Cmd+Z undoes them; anything that rewrites or removes what someone wrote is shown to you first, as a banner on that map. Full detail in mcp/README.md.

Claude Code plugin

Ties a Claude Code session to one card of a TabTree board. Claude knows which card it is working on — even after /clear — and your commits land on that card as a comment, without you writing anything.

claude plugin marketplace add ai4xedu/tabtree-mcp

claude plugin install tabtree@tabtree

Then give it your connector key (tt_live_…, from TabTree → ⚙️ Settings → Account → Claude connector): inside a Claude Code session, run /plugin configure tabtree@tabtree. From a shell, claude plugin configure tabtree@tabtree --values-stdin reads it as {"api_key":"tt_live_…"} on standard input. The key is kept by Claude Code, never written into a file of your repository.

CommandWhat it does
/tabtree:linkLinks this git repository to one board — writes .tabtree.json (the board's id, no secret), so teammates share the link.
/tabtree:nextPicks the card to work on next, reads its brief, moves it to the in-progress column.
/tabtree:statusSays which board and card this session is tied to.
/tabtree:doneWrites the deliverable onto the card, for your approval in TabTree.
atelier-vision-okrFacilitates a vision / mission / OKR session — in French, the language it was built to run workshops in — and writes the result as a canvas you can present.

Once a repository is linked, each session starts with a one-paragraph summary of the board and the current card, and the commits made during a session become one comment on the card: hash, subject and branch — never a diff, a file or a secret. A hook never blocks a session: when TabTree does not answer, Claude goes on without it. The connector itself ships inside the plugin (the same tabtree-mcp.mjs as on npm), so the twelve tools above are in the session.

Screenshots

The same document as status columns — every card is still a node of the map.

Arrows stay attached to the boxes when you move them.

Licence

Different licences, and the distinction matters:

  • The connector in mcp/ is free to use, copy, redistribute and modify, for any purpose — see mcp/LICENSE.md. It is given away on purpose.
  • The plugin in plugins/tabtree/ carries the connector's licence file, and the workshop skill keeps its own (plugins/tabtree/skills/atelier-vision-okr/LICENSE.md): free on the same terms, commercial workshops included. Each text names what it covers.
  • The app is a commercial service at tabtree.app; its source is not in this repository.
  • The template outlines are yours to copy and adapt freely.
