Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00997 | $0.00997 |
| Opus 5 | $0.00498 | $0.00498 |
| Sonnet 5 | $0.00199 | $0.00199 |
| Haiku 4.5 | $0.00100 | $0.00100 |
Grade A, and why
mcp-atom-of-thoughts CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mcp-atom-of-thoughts (v3)
MCP server for structured reasoning via Atom of Thoughts. Decomposes problems into atomic units (premise → reasoning → hypothesis → verification → conclusion) with confidence tracking, session scoping, and on-demand D3 visualization.
Architecture
index.ts — MCP server entry, tool dispatch, viz attachment, approval server
atom-server.ts — Full AoT (depth 5, decomposition-contraction) with session-scoped state
atom-light-server.ts — AoT-fast (depth 3) — extends atom-server, lighter response shape
tools.ts — MCP tool definitions (3 tools)
types.ts — AtomData, Session, GraphNode, GraphLink, ApprovalResult
config.ts — CLI arg parsing (--mode, --viz, --max-depth, --output-dir, --downloads-dir)
visualization.ts — D3.js interactive graph renderer (callback URL embedded)
graph-export.ts — JSON export of atom graph
approval.ts — File-based approval polling (fallback path)
approval-server.ts — Local 127.0.0.1 HTTP listener for browser → server callbacks
d3-bundle.ts — D3 asset bundler
MCP Tools (3)
| Tool | Purpose |
|---|---|
AoT-fast |
Default reasoning. Depth 3, auto-suggests conclusions. Set viz:true during planning |
AoT-full |
Deep reasoning with decomposition-contraction. Depth 5. Same shape as AoT-fast, plus decomposition controls |
atomcommands |
Lifecycle/meta: decompose, complete_decomposition, termination_status, best_conclusion, set_max_depth, export, check_approval, new_session, switch_session, list_sessions, reset_session |
Atom Types
premise (P) → reasoning (R) → hypothesis (H) → verification (V) → conclusion (C)
Each atom: atomId, content, atomType (required), dependencies (default []), confidence (default 0.7), optional viz (default false), optional sessionId (default active session).
Sessions
- All atom state scoped to a
sessionId(default"default"). - Auto-archive on
shouldTerminate; auto-spawn freshdefault-Non next zero-dep atom. - Two reasoning problems in the same MCP process do not collide.
- Every response includes
sessionId.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp-atom-of-thoughts CLAUDE.md is an instructions file published in the GitHub repository dioptx/mcp-atom-of-thoughts (90 stars, last pushed 4mo ago), licensed MIT. It adds 997 tokens to every session, about $0.0050 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
