An MCP server implementation that enhances AI model capabilities with structured, retrieval-augmented thinking processes.
RAT MCP Server (Node.js)
Retrieval Augmented Thinking MCP Server - A reasoning tool that processes structured thoughts with metrics, branching, and revision capabilities.
Installation
Simple 3-Step Process
git clone https://github.com/stat-guy/retrieval-augmented-thinking.git
cd retrieval-augmented-thinking
npm install -g .
Verify Installation
Test that the installation worked:
npx mcp-server-rat-node --help
Success indicator: If you see RAT MCP Server (Node.js) running on stdio, your installation is ready!
Claude Desktop Configuration
Add to your Claude Desktop configuration file:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json
{
"mcpServers": {
"retrieval-augmented-thinking": {
"command": "npx",
"args": ["mcp-server-rat-node"]
}
}
}
After adding the configuration, restart Claude Desktop to load the RAT server.
Usage
The server provides a single rat tool for processing structured thoughts:
// Basic usage
{
"thought": "I need to analyze this problem step by step...",
"nextThoughtNeeded": true,
"thoughtNumber": 1,
"totalThoughts": 3
}
// With revision
{
"thought": "Let me reconsider my previous analysis...",
"nextThoughtNeeded": false,
"thoughtNumber": 2,
"totalThoughts": 3,
"isRevision": true,
"revisesThought": 1
}
// With branching
{
"thought": "Alternative approach: what if we consider...",
"nextThoughtNeeded": true,
"thoughtNumber": 2,
"totalThoughts": 4,
"branchFromThought": 1,
"branchId": "alt-path-1"
}
Tool Parameters
Required
thought(string): The thought content to processnextThoughtNeeded(boolean): Whether another thought is needed to continuethoughtNumber(integer): Current thought number in the sequencetotalThoughts(integer): Total expected thoughts (adjustable)
Optional
isRevision(boolean): Whether this revises a previous thoughtrevisesThought(integer): The thought number being revisedbranchFromThought(integer): Thought number to branch frombranchId(string): Unique identifier for this branchneedsMoreThoughts(boolean): Extend beyond totalThoughts if needed

}
Troubleshooting
If Installation Fails
The installation process includes automatic permission fixes. If you encounter issues:
- Ensure you have Node.js and npm installed
- Try the alternative installation method:
npm install -g git+https://github.com/stat-guy/retrieval-augmented-thinking.git - For rare permission issues:
chmod +x $(npm bin -g)/mcp-server-rat-node
Verification Steps
Before configuring Claude Desktop, always verify:
npx mcp-server-rat-node --help
If this shows "RAT MCP Server (Node.js) running on stdio", you're ready to configure Claude Desktop.
