What is the Think Tool MCP Server?

Empowers Claude to improve complex reasoning through a dedicated structured thinking space.

What the server does

A Model Context Protocol (MCP) server implementing the "think" tool for improving Claude's complex reasoning capabilities.

This MCP server implements the "think" tool as described in Anthropic's blog post, which provides Claude with a dedicated space for structured thinking during complex problem-solving tasks. The think tool has been shown to significantly improve performance in complex tasks requiring policy adherence and reasoning in long chains of tool calls.

  • Structured Thinking Space — Provides Claude with a dedicated place to break down complex problems
  • Thought History — Maintains a log of all thoughts with timestamps for reference
  • Statistics and Analysis — Offers metadata about thinking patterns
  • Clean Slate Option — Allows clearing thought history when starting fresh
