## Description

MCP Think Tool Server implements Anthropic's 'think' tool for Claude, providing a dedicated space for structured reasoning during complex problem-solving tasks. Developed by cgize, this TypeScript server maintains a timestamped log of thoughts that Claude can record, retrieve, clear, and analyze through four specialized tools. The implementation is particularly valuable for scenarios requiring complex tool chains, policy adherence, sequential decision making, and multi-step analysis, allowing Claude to break down problems methodically and improve performance in reasoning-intensive tasks without switching contexts.
