Clear Thought

Provides 11 specialized cognitive tools including mental models, design patterns, debugging approaches, and scientific reasoning frameworks for systematic problem-solving and enhanced analytical thinking.

A systematic thinking and problem-solving MCP server built by Chirag Singhal that provides 11 specialized cognitive tools for enhanced reasoning capabilities. The implementation offers mental models (First Principles, Opportunity Cost, Occam's Razor), design patterns for software architecture, programming paradigms, debugging approaches, sequential thinking with revision support, collaborative reasoning with multi-persona simulation, structured decision frameworks, metacognitive monitoring for knowledge assessment, scientific method tools for hypothesis testing, dialectical argumentation, and visual reasoning for diagrammatic problem-solving. Each tool uses TypeScript with comprehensive input validation, colored console output via chalk, and structured JSON responses, making it useful for complex analysis tasks, architectural decisions, systematic debugging, and multi-step reasoning workflows where different cognitive approaches can be applied based on the problem type.
