Overview

Matryoshka Mind Map MCP server connects AI agents to the Matryoshka Mind Map app, allowing them to read and modify nested mind maps and TODOs. Agents can list maps, turn conversational ideas into structured nodes, complete tasks, and import notes or Markdown. It runs locally through an MCP client and uses a Matryoshka account authenticated with Google, Apple, or email. Reach for it when conversations need to become organized plans, task lists, or reusable map content.

Use cases

  • Organize trip-planning ideas into a nested map
  • Add conversation-derived tasks to an existing map
  • Mark completed TODOs from natural-language updates
  • Import Markdown notes into a structured map

Key features

  • List Matryoshka maps
  • Create nested map content
  • Add tasks to maps
  • Complete TODO items
  • Import notes and Markdown
  • Local account authentication

How Matryoshka Mind Map works

What Matryoshka Mind Map does

Matryoshka Mind Map MCP server lets an AI agent work with maps stored in the Matryoshka Mind Map app. The app supports nested mind maps and TODOs, so an agent can help organize information into hierarchical topics, add tasks beneath existing nodes, and mark completed work.

Typical requests include listing the maps in an account, adding a named task to a selected map, converting ideas from a conversation into nested structure, and importing long notes or Markdown. An agent can also update a TODO when the user reports that a task is finished.

Matryoshka Mind Map is available through a web app and mobile apps for iOS and Android. The MCP connection operates on the user's own Matryoshka account rather than a shared workspace.

How it works

The server runs on the user's computer while the user interacts with an AI agent. It communicates with the selected MCP client over the local server command, and reads or writes map data directly in the authenticated Matryoshka account.

Authentication can be initiated by asking the agent to sign in. Claude Desktop opens a browser for Google or Apple approval, or for email-and-password sign-in. Terminal users can authenticate with the mmm-login command and choose google, apple, or email. Anonymous-only Matryoshka accounts cannot be used; the account must be linked to one of those supported sign-in methods.

When a map is read for the first time, Claude requests permission. The server is not an always-on service: it runs only during interaction with the agent. Login information remains on the local computer, and map titles and contents are not sent to the developer. On days when the server writes to maps, it records only the date and a count of such days in the account.

Setup and configuration

Claude Desktop users can download the mmm-mcp-server.mcpb package from the project's latest GitHub release, open it, and select Install. After installation, ask Claude to sign in to Matryoshka and approve the browser authentication flow.

For Claude Code and other MCP clients, Node.js 18 or newer is required. Register npx -y mmm-mcp-server@latest as the server command. Claude Code can be configured with:

Terminal
claude mcp add mmm -- npx -y mmm-mcp-server@latest

Authentication can also be started from a terminal:

Terminal
npx -y -p mmm-mcp-server@latest mmm-login login --method google

Replace google with apple or email when appropriate. Other MCP clients should register the same npx command according to their server configuration format.

Tools and capabilities

  • List the user's Matryoshka maps.
  • Read map content through the connected account.
  • Create nested map content from an ongoing conversation.
  • Add tasks to a named map.
  • Mark TODO items as complete.
  • Import long notes or Markdown into a map.

Limitations and notes

The integration requires a Matryoshka account linked to Google, Apple, or an email address; anonymous accounts are unsuitable. Map access is subject to client permission prompts, including the first read of a map in Claude. The server is local and session-based rather than an always-running remote service. Usage telemetry for write activity is limited to dates and counts, while map titles and contents remain outside the developer's view.
