MCTS MCP Server

What is MCTS MCP Server?

The MCTS MCP Server is a Model Context Protocol server that exposes an Advanced Bayesian Monte Carlo Tree Search (MCTS) engine for AI-assisted analysis and reasoning. It enables AI assistants like Claude to systematically explore different angles and interpretations of a topic, question, or text input using a probabilistic MCTS algorithm.

How to use MCTS MCP Server?

Install via the automatic setup script (python setup.py) or manually using UV. Configure API keys in a .env file and add the server’s configuration to Claude Desktop’s config file. Once set up, the AI assistant can call tools like initialize_mcts, run_mcts, generate_synthesis, and set_active_llm to perform deep analysis.

Key features of MCTS MCP Server

• Bayesian MCTS: balances exploration vs. exploitation probabilistically
• Multi-iteration analysis with multiple simulations per iteration
• State persistence across chat turns
• Approach taxonomy classifying thoughts into philosophical families
• Thompson sampling or UCT for node selection
• Surprise detection for novel analysis directions

Use cases of MCTS MCP Server

• Deep analysis of complex topics or questions
• Exploring multiple interpretations of a text input
• Iterative reasoning with state persistence across chat turns
• Comparing analytical pathways generated by different MCTS configurations
• Using local or cloud LLMs to drive MCTS analysis

FAQ from MCTS MCP Server

What runtime and dependencies are required?

Python 3.10+ and the UV package manager. Dependencies are installed automatically by the setup script.

How do I obtain and configure API keys?

Edit the .env file created during setup with your API keys for OpenAI, Anthropic, and/or Google Gemini. For Ollama, no API key is needed.

Does the MCTS server call the LLM directly?

No. The server uses a local inference approach; it does not call the LLM directly. It provides tools that the AI assistant (e.g., Claude) calls to perform MCTS analysis.

What should I do if Claude Desktop does not detect the server?

Verify the config file location and syntax, ensure paths are absolute and correct, restart Claude Desktop completely, and check Claude Desktop logs
