Unconventional Thinking MCP server

This TypeScript-based MCP server implements an unreasonable thinking system that helps generate unconventional solutions to problems by challenging conventional wisdom, creating different branches of thinking, and organizing thoughts in a structured session.

Installation

To use the Unreasonable Thinking Server with Claude Desktop, you need to add server configuration to your Claude Desktop config file:

On MacOS:

~/Library/Application Support/Claude/claude_desktop_config.json

On Windows:

%APPDATA%/Claude/claude_desktop_config.json

Add the following configuration to your config file:

{
  "mcpServers": {
    "unreasonable-thinking-server": {
      "command": "/path/to/unreasonable-thinking-server/build/index.js"
    }
  }
}

Replace /path/to/unreasonable-thinking-server/build/index.js with the actual path to the built server on your system.

Usage

The Unreasonable Thinking Server provides several tools to help you generate and manage unconventional thoughts:

Generate Unreasonable Thoughts

The generate_unreasonable_thought tool creates new unconventional thoughts that challenge conventional wisdom:

• Takes a problem description as input
• Can build upon or rebel against previous thoughts
• Helps break through conventional thinking patterns

Branch Thoughts

Use the branch_thought tool to create new branches of thinking in different directions:

• Create more extreme versions of a thought
• Generate opposite perspectives
• Explore tangential ideas
• Maintains connection to source thoughts for traceability

List Thoughts

The list_thoughts tool helps you track and organize thoughts in your session:

• View all thoughts generated in the current session
• Filter thoughts by branch
• See relationships between different thoughts

Debugging

If you encounter issues with the server, you can use the MCP Inspector for debugging:

npm run inspector

This will provide a URL to access debugging tools in your browser, which is helpful since MCP servers communicate over stdio and can be challenging to debug directly.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "unreasonable-thinking-server" '{"command":"/path/to/unreasonable-thinking-server/build/index.js"}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "unreasonable-thinking-server": {
            "command": "/path/to/unreasonable-thinking-server/build/index.js"
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "unreasonable-thinking-server": {
            "command": "/path/to/unreasonable-thinking-server/build/index.js"
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
