MCP Think Tool Server

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

Overview

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.

Features
