Overview

AI-generated overview

Connects an AI assistant to a Matryoshka Mind Map account so it can write nested to-dos and diagrams and read back your edits.

What you can do
  • Write nested to-dos and Mermaid diagrams into your maps
  • Read your maps back, including edits and check-offs you made in the app
  • Work on maps as the signed-in user, under the app's own access control
  • No tool list is published, so exact operations are not documented here
When to use it
Useful if you keep tasks and ideas in Matryoshka Mind Map and want an assistant to turn conversations or meetings into nested to-dos and diagrams, then pick up your changes on the next turn.
Requirements
A remote MCP endpoint at mmm.spheres.jp over streamable HTTP, with OAuth sign-in required. A Matryoshka Mind Map account and the app (web, App Store or Google Play) are needed; the app is free to start. No environment variables or headers are declared.
Before you install
The assistant can write to your maps, not just read them. The first read of a map's contents prompts for your permission. Map contents are not stored on the server, but content passed to your AI is subject to that provider's terms. You can disconnect from your AI's settings, and deleting your account removes the grants.

Installation

In SourceWeft

  1. Open Matryoshka Mind Map in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.nhorie-canal%2Fmmm-mcp-server/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Matryoshka Mind Map MCP Server

English | 日本語

Work with your AI in maps, not text. Your usual AI, such as Claude, writes nested to-dos and Mermaid diagrams into Matryoshka Mind Map. You look, edit and check things off in the app, and the AI reads your changes back.

[Asking an AI agent to plan a trip fills a Matryoshka map, and "I booked the hotel" checks it off]

The app (free to start): Web · App Store · Google Play

From preparing the app to connecting your AI, the recommended instructions and everyday use, in order.

Privacy

  • It reads and writes your maps as you, only when your AI asks. The same access control as the app applies
  • Map contents are not stored on the server or written to logs. The server keeps only connection grants (hashed) and daily call counts (deleted after 3 days)
  • The days you wrote (dates and a count only) and your device's time zone are kept in a part of your account only you can read. The former is used only to count users
  • The first time a map's contents are read, the AI asks for your permission
  • You can disconnect from your AI's settings. Deleting your account removes the grants. Content passed to your AI is subject to its provider's terms

See Privacy for details.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
