Logical Thinking

A Model Context Protocol (MCP) server for ChatGPT Apps that helps structure and visualize logical thinking processes through interactive issue trees.

What is this?

This MCP server enables ChatGPT to help you break down complex problems into structured issue trees. It provides tools for creating, organizing, and visualizing logical hierarchies, making it easier to analyze problems systematically.

Key Features

• Issue Tree Management: Create and manage hierarchical issue trees to structure your thinking
• Interactive Breakdown: Break down complex issues into smaller, manageable sub-issues
• Visual Tree Representation: View your issue tree with an interactive React-based UI in ChatGPT
• Persistent Storage: Issue trees are automatically saved locally and persist across sessions
• ChatGPT Apps Integration: Designed specifically for ChatGPT Apps with native widget support

Available Tools

The server provides the following MCP tools:

• issue: Create and manage root issues
• breakdown: Break down an issue into multiple sub-issues
• child-issue: Add a single child issue to an existing issue
• tree: Retrieve and visualize the complete issue tree

Usage Example

Once configured in ChatGPT, you can interact naturally:

You: "Help me think through how to improve customer retention"

ChatGPT will use the MCP tools to:
1. Create a root issue
2. Break it down into logical sub-issues
3. Visualize the tree structure in an interactive widget
4. Help you analyze each branch systematically

The issue tree is displayed in a visual widget that updates as you add and refine issues.

Data Storage

Issue trees are stored locally at:

• Default: <system-temp-dir>/mcp-logical-thinking/logical-tree.json
• Configurable via the persistence layer
