## Overview

**ThinkSquare** is an AI chess assistant built as an **MCP Server**. It enables users to:

- Analyze and Annotate PGN Games with AI insights
- Play Chess interactively through any compatible MCP Client (e.g., Claude Desktop, Cline [VSCode extension]) 
- Suggest Strong Moves powered by LLMs and cloud infrastructure  


---

## Tech Stack

- [Gradio](https://gradio.app/)
  - UI + MCP Server interface  
- [Modal](https://modal.com/)
  - For cloud-based compute [This does the heavy lifting by providing on-demand compute for both play_chess and annotate functions.]
- [SambaNova](https://sambanova.ai/)
  - For LLM inference. [ThinkSquare uses the Meta-Llama-3.3-70B-Instruct model]
- [Stockfish](https://stockfishchess.org/)
  - As the core chess engine

---

## How to Use

You can use any compatible MCP Client to connect to ThinkSquare, such as:

- [Claude Desktop](https://claude.ai/download)  
- [Cline](https://cline.bot/) 
- [Cursor](https://www.cursor.com/)  
- Or even another Gradio MCP Client Space  

**ThinkSquare** will automatically respond to tool calls like:  
play_chess, suggest_move, annotate_pgn
