Think MCP

🚀 Think MCP Tool

Think MCP is a project that implements an MCP (Model Context Protocol) server, offering a "think" tool for structured reasoning and enhancing the reasoning ability of agents in agent-based AI workflows. Inspired by Anthropic's engineering article The "think" tool: Enabling Claude to stop and think in complex tool use situations.

According to the references, adding the "think" tool can improve the model's evaluation metrics, enabling it to perform reasoning even without native advanced reasoning skills.

🚀 Quick Start

What is the "Think" Tool?

The "think" tool allows AI agents to pause and record a clear thought during complex reasoning or multi-step tool use. It doesn't modify the environment or database but appends the thought to the log, helping the agent process information, backtrack, or adhere to detailed policies.

This approach is particularly suitable for:

• Tool output analysis (processing the results of previous tool calls)
• Policy-intensive environments (verifying compliance with guidelines)
• Sequential decision-making (each step builds on the previous one)

✨ Features

• Implements the "think" tool described in Anthropic's research.
• Based on the standard MCP server, using mcp[cli].
• Ready to be integrated into Claude or other agent-based large language models.

💻 Usage Examples

Basic Usage

MCP Server Configuration

Add this MCP server to your favorite agent.

"mcpServers": {
    "think-mcp": {
        "command": "uvx",
        "args": ["think-mcp"],
        "enabled": true
    }
}

Tool Definition

The definition of the "think" tool is as follows:

• Input: thought (string) — A thought to be considered.
• Action: Append the thought to the log for structured reasoning.

Advanced Usage

Add other tools for your agent to use:

• Criticism
• Planning
• Search

"mcpServers": {
    "think-mcp": {
        "command": "uvx",
        "args": ["think-mcp", "--advanced"],
        "enabled": true,
        "env": {
            "TAVILY_API_KEY": ... YOUR TAVILY API KEY HERE ...
        }
    }
}
