Dual-Cycle Reasoner

MCP Dual-Cycle Reasoner

A Model Context Protocol (MCP) server implementing the Dual-Cycle Metacognitive Reasoning Framework for autonomous agents. This tool empowers agents with greater self-awareness and reliability through intelligent loop detection and experience acquisition.

Description

The MCP Dual-Cycle Reasoner is a sophisticated tool designed to enhance the autonomy and reliability of AI agents. By implementing a dual-cycle metacognitive framework, it provides agents with the ability to monitor their own cognitive processes, detect when they are stuck in repetitive loops, and learn from past experiences to make better decisions.

The framework consists of two main components:

• Sentinel: Monitors the agent's actions and detects anomalies, such as action repetition, state invariance, and progress stagnation.
• Adjudicator: Manages a case base of past experiences, allowing the agent to store and retrieve solutions to previously encountered problems.

This server is built with TypeScript and leverages high-performance libraries for statistical analysis, natural language processing, and semantic similarity, enabling advanced features like entropy-based anomaly detection, NLI-based text analysis, and intelligent case management.

Key Features

• 📊 Advanced Statistical Analysis: Entropy-based anomaly detection and time series analysis.
• 🧠 Enhanced Case-Based Reasoning: Semantic similarity matching with NLI-based text analysis.
• 🎯 Multi-Strategy Detection: Statistical, pattern-based, and hybrid loop detection.
• 📈 Time Series Analysis: Trend detection and cyclical pattern recognition.
• 🔧 Configurable Detection: Domain-specific thresholds and progress indicators.
• 🎨 Intelligent Case Management: Quality scoring, deduplication, and usage-based optimization.
• 🚀 High-Performance Libraries: Built with simple-statistics, natural, compromise, and HuggingFace Transformers.
