The Retrieval-Augmented Thinking MCP Server enhances AI models with structured, adaptive reasoning processes. Key capabilities include:
Maintains adaptive thought chains with branching and revision capabilities
Generates and validates hypotheses through iterative cycles
Preserves context coherence across non-linear reasoning paths
Supports dynamic scope adjustment and trajectory refinement
Manages parallel reasoning paths with branch identifiers
Implements recursive refinement through structured revision cycles
Validates solutions through multi-step verification protocols
Tracks thought chain metrics for quality assessment
Analyzes reasoning patterns for structure and coherence
Enables iterative hypothesis generation and validation cycles through structured thought processes, supporting creation, testing, and refinement of hypotheses with verification checkpoints.
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
Verify Installation
Test that the installation worked:
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
After adding the configuration, restart Claude Desktop to load the RAT server.
Usage
The server provides a single rat
tool for processing structured thoughts:
