Atom of Thoughts (AoT) MCP Server

What is Atom of Thoughts (AoT)?

An MCP server implementing Atom of Thoughts, a decomposition-based reasoning framework from the research paper “Atom of Thoughts for Markov LLM Test-Time Scaling” (Teng et al., 2025). It structures problem‑solving into atomic units (premise, reasoning, hypothesis, verification, conclusion) with explicit dependencies and confidence scores, offering two tools: the full AoT for deep analysis and AoT‑light for faster, shallower reasoning.

How to use Atom of Thoughts (AoT)?

Register the server in your Claude Desktop or Cline MCP settings with a JSON configuration that points to the built index.js file. Example: { "mcpServers": { "atom-of-thoughts": { "command": "node", "args": ["/ABSOLUTE/PATH/TO/PARENT/FOLDER/atom-of-thoughts/build/index.js"] } } }. Alternatively, install via Smithery: npx -y @smithery/cli install @kbsooo/mcp_atom_of_thoughts --client claude. After configuration, restart the client and use the provided tools (AoT, AoT‑light, atomcommands).

Key features of Atom of Thoughts (AoT)

• Decomposition‑contraction mechanism: break atoms into sub‑atoms and contract after verification.
• Automatic termination when max depth is reached or a high‑confidence conclusion is found.
• Five atom types: premise, reasoning, hypothesis, verification, conclusion.
• Full AoT tool with a maximum depth of 5; AoT‑light with depth 3 for speed.
• Command tool (atomcommands) to control decomposition, depth, and retrieve status.
• Explicit confidence evaluation (0–1) and dependency tracking between atoms.

Use cases of Atom of Thoughts (AoT)

• Solving complex problems requiring multi‑step reasoning.
• Generating and verifying hypotheses from multiple perspectives.
• Deriving high‑confidence conclusions for accuracy‑critical tasks.
• Minimizing logical errors in decision‑making with rigorous verification.
• Quick brainstorming with AoT‑light when speed is prioritized.
