Atom of Thoughts (AoT) is a Model Context Protocol (MCP) server implementing a decomposition-based reasoning framework. It breaks down intricate problems into smaller, manageable 'atoms' of thought, interconnected by dependencies, to deliver robust and verified solutions. The tool offers both a full-featured version (AoT) for deep analysis and a lightweight version (AoT-light) optimized for speed. AoT facilitates problem-solving, hypothesis generation, and decision-making across various scenarios.
