- Implements the “think” tool as described in Anthropic’s research.
- Minimal, standards‑based MCP server using the mcp[cli] package.
- Adds structured reasoning capabilities to models that lack native advanced reasoning.
- Advanced mode includes extra tools: criticize, plan, and search.
- Easy integration with any MCP‑compatible agent framework.
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Think MCP ToolCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Add the MCP server to your agent’s configuration using uvx with argument think-mcp. For advanced mode, add --advanced and set the TAVILY_API_KEY environment variable. The tool accepts a thought string input and appends it to the log.

Think MCP is an implementation of an MCP (Model Context Protocol) server that provides a "think" tool for structured reasoning in agentic AI workflows. This project is inspired by the Anthropic engineering article: The "think" tool: Enabling Claude to stop and think in complex tool use situations.
According to the referenced article, adding the think tool can lead to improved evaluation metrics by enabling reasoning capabilities even in models that do not natively possess advanced reasoning skills.

What is the "think" tool?
The "think" tool allows an AI agent to pause and record an explicit thought during complex reasoning or multi-step tool use. It does not change the environment or database, but appends the thought to the log, helping the agent process information, backtrack, or comply with detailed policies.This approach is especially useful for:
- Tool output analysis (processing results of previous tool calls)
- Policy-heavy environments (verifying compliance with guidelines)
- Sequential decision making (where each step builds on previous ones)
Features
- Implements the "think" tool as described in Anthropic's research - Minimal, standards-based MCP server using [mcp[cli]](https://pypi.org/project/mcp/) - Ready for integration with Claude or other agentic LLMsUsage

Tool definition
The "think" tool is defined as: - Input:thought (string) — A thought to think about.
- Behavior: Appends the thought to the log for structured reasoning.
Advanced mode
