abhinav-mangla/think-tool-mcp
A Model Context Protocol (MCP) server that implements the "think" tool for enhancing complex reasoning capabilities in Large Language Models (LLMs). This tool provides LLMs with a dedicated space for structured thinking during problem-solving tasks, significantly improving performance in complex scenarios requiring policy adherence and multi-step reasoning.

}The Think Tool MCP server is based on Anthropic's research demonstrating that providing LLMs with a dedicated "thinking space" dramatically improves performance on complex tasks. This tool allows any compatible LLM (Claude, GPT-4, and others) to:
Structured Thinking Space: Provides LLMs with a dedicated environment for complex reasoning
Memory Aid: Helps maintain context during long chains of tool calls
Policy Verification: Enables careful policy adherence checking
Problem Decomposition: Supports breaking down complex problems into steps
Lightweight: Minimal overhead with efficient MCP implementation
Easy Integration: Simple setup with popular AI platforms (Cursor, Claude Desktop, etc.)
TypeScript: Built with TypeScript for type safety and better development experience
Universal Compatibility: Works with any LLM that supports the Model Context Protocol
