MindManager MCP Server by robertZaufall - MCP Server

MindManager MCP Server

A Model Context Protocol (MCP) server implementation for the mindm library, providing a standardized interface to interact with MindManager on Windows and macOS.

Overview

This server allows you to programmatically interact with MindManager through the Model Context Protocol (MCP), a standardized way to provide context and tools to LLMs. It leverages the mindm library to manipulate MindManager documents, topics, relationships, and other mindmap elements.

Animated examples (using Codex in VSCode on Windows)

Example Refining a single topic including tags, icons for the new topics:

get the current Mindmanager mindmap as mermaid (full), refine the given topics at least two levels deep (not just topics), add a tag "Important" to the 3 top most important topics and add corresponding stock icons to every topic but the central topic and create the new MindManager mindmap

Example Refining a single topic including generating text in notes for the new topics:
Example Cloning a map including all supported topic properties:

Other examples

Client

get the current MindManager mindmap, translate every topic to German and create a new MindManager mindmap (simple).

get the current MindManager mindmap, refine each topic 2 levels and create a new MindManager mindmap (simple).

Shell:

codex exec "get the current MindManager mindmap, add a meaningful emoji to every topic and create new MindManager mindmap (simple)"

remark: emojis only work on macOS.

Features

Retrieve mindmap structure and central topics
Export mindmaps to Mermaid, Markdown, JSON formats to be used in LLM chats
Create MindManager mindmaps directly from Mermaid (full or simplified syntax)
Fetch MindManager and package versions for quick diagnostics
Get information about MindManager installation and library folders
Get current selection from MindManager

Planned Features

Add, modify, and manipulate topics and subtopics without Mermaid roundtrips
Add relationships between topics
Add tags to topics
Set document background images

            "VIRTUAL_ENV": "/Users/master/git/mindm-mcp/.venv"
        }
      }
  }
}

Hint: If the MCP server does not show up with the hammer icon on Windows, close Claude Desktop and kill all background processes.

macOS: Support for topics, notes, and relationships (limited support compared to Windows)

Integration with Claude and other LLMs

This MCP server can be installed in Claude Desktop or other MCP-compatible applications, allowing LLMs to:

Access mindmap content
Manipulate mindmaps (coming)
Create new mindmaps based on LLM-generated content (coming)

Troubleshooting

Ensure MindManager is running before starting the server
For macOS, make sure you allow Claude Desktop to automate MindManager
