Think Tool

Provides a dedicated space for structured reasoning during complex problem-solving tasks, enabling models to maintain timestamped thought logs that can be reviewed, cleared, and analyzed for improved performance in tasks requiring long chains of reasoning.

The MCP Think Tool Server implements Anthropic's 'think' tool for Claude and other LLMs, providing a dedicated space for structured reasoning during complex problem-solving tasks. It maintains a timestamped log of thoughts that can be reviewed, cleared, or analyzed for statistics, enabling models to break down problems systematically, ensure policy adherence, and process complex tool outputs. Built using FastMCP, the server exposes four tools: think for recording thoughts, get_thoughts for retrieving the thinking history, clear_thoughts for resetting, and get_thought_stats for analyzing thinking patterns - making it particularly valuable for improving performance in tasks requiring long chains of reasoning.
