MCP 服务器

Thinking Tools

Provides five rigorous reasoning protocols (debate, red team, audit_argument, threat_model, check_study) that run on the AI you're already using, requiring no extra API keys or costs.

Thinking Tools 🧠

Five rigorous reasoning protocols for Claude & ChatGPT. Free, open-source, and zero extra credits — they run on the AI you're already talking to.

One MCP server. Works in both Claude and ChatGPT.

Tool	What it does
`debate`	Convenes an expert panel derived from your question, argues it out (steelman → attack), then delivers a verdict with the strongest dissent preserved and what evidence would flip it
`red_team`	Steelmans your plan, then hunts hidden assumptions, failure modes, misuse, scaling breakpoints and single points of failure. 12-month pre-mortem. Risks ranked by likelihood × impact, each with the cheapest fix or a falsifying test
`audit_argument`	Reconstructs any text's argument, names quote-anchored fallacies, biases and rhetoric, shows what evidence is missing — and rates argument quality and conclusion truth separately
`threat_model`	Defensive STRIDE review: assets, actors, trust boundaries, data flows → rated threats, each with a named, located control. Hardening only, never exploits
`check_study`	Extracts design/N/baseline/effect size/CI/p from a study or statistic; flags p-hacking, missing controls, survivorship bias, relative-risk inflation; verdict separates weak study from false claim

How it's free

The server runs no AI. Each tool returns an expert-designed protocol as plain text; your own Claude/ChatGPT reads it and does the reasoning in the same turn. No API key, no second bill.

That's also why you invoke it explicitly ("Debate this: ..."). An MCP server can't intercept your message before the AI sees it — that's a platform rule, not a missing feature.

Design principles baked into every protocol

Steelman before attacking — never critique a weaker version than you'd defend
Quote before accusing — no quote, no fallacy claim
Never fake consensus — dissent is preserved, split verdicts are reported as split
Invent nothing — no fabricated stats, sources, or citations; uncertain recall is labelled
Separate "bad argument" from "false conclusion" — a bad argument can have a true conclusion
