Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 2 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-02

2 capabilities in this set.

Part of 2 available through Critical Thinking Prover.

  1. 01

    Validate critical thinking

    This capability forces your agent to validate its reasoning against five specific pivots: surfacing assumptions, applying competing frameworks, weighing evidence, mapping consequences, and bounding confidence. It rejects conclusions that lack depth or rely on one-sided evidence.

  2. 02

    Validate task completion

    This capability verifies that an agent actually finished a task by mapping requirements to specific file changes and providing execution logs. It catches incomplete work, unverified code changes, and placeholder implementations.

Real work

What teams actually run

01

Technical Architecture Reviews

Validate whether a proposed infrastructure change actually solves the identified bottleneck.

02

Business Strategy Stress-Testing

Check if a market entry plan ignores behavioral or organizational consequences.

03

Code Migration Verification

Ensure an agent has actually completed all requirements and verified the build.

04

Policy and Risk Assessment

Map the second-order effects of a new organizational policy or rule.

Automate a task

Put Critical Thinking Prover to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Critical Thinking Prover works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Critical Thinking Prover to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 2 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Critical Thinking Prover, so you can see the experience inside your AI.

It does not authenticate your account with Critical Thinking Prover. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Critical Thinking Prover owners hand off.

This MCP is for professionals who rely on AI agents for high-stakes decision making and technical execution.

  • 01

    Software Architects

    They use it to validate technical migrations and system design decisions.

  • 02

    Product Managers

    They use it to stress-test product roadmaps and feature assumptions.

  • 03

    Strategic Consultants

    They use it to ensure business recommendations aren't based on mono-perspective reasoning.

FAQ

Questions Critical Thinking Prover owners ask.

  • 01

    How is this different from a system prompt?

    System prompts are suggestions that agents often ignore. This MCP uses a capability schema that makes validation an obligation, meaning the agent must provide specific data to pass.

  • 02

    What happens if the agent's reasoning is rejected?

    The capability returns a rejection with specific feedback, such as identifying assumption blindness or confirmation bias, forcing the agent to re-evaluate.

  • 03

    Can I use this for coding tasks?

    Yes. The validate_task_completion capability is specifically designed to verify that code changes are real, mapped to files, and backed by execution logs.

  • 04

    Does this work with any AI client?

    It works with any MCP-compatible client, including Claude, Cursor, and Windsurf.

  • 05

    What is 'false precision'?

    False precision is when an agent provides a specific, confident answer without acknowledging the uncertainty or the conditions under which that answer might change.

  • 06

    Does Critical Thinking Prover generate answers to complex problems?

    No. Critical Thinking Prover performs zero content generation. It forces the AI agent to structure its own reasoning into verifiable fields. assumptions, frameworks, evidence, consequences, confidence bounds. then validates that the reasoning is logically consistent. The agent does all the thinking. The capability catches blind spots.

  • 07

    How is this different from Sequential Thinking?

    Sequential Thinking structures thoughts in a linear chain. step 1, step 2, step 3. It's domain-agnostic and doesn't validate reasoning quality. Critical Thinking Prover is orthogonal: it doesn't sequence thoughts, it validates that the reasoning addresses five specific cognitive failure modes. assumption blindness, mono-perspective, confirmation bias, scope neglect, and false precision. You can use both together: Sequential Thinking to decompose the problem, Critical Thinking Prover to validate the conclusion.

  • 08

    What types of problems does this apply to?

    Any complex problem where the answer is not obvious and the reasoning matters more than the conclusion. Technical architecture decisions, business strategy, policy design, ethical dilemmas, resource allocation, organizational restructuring, risk assessment, investment analysis, product prioritization. If the problem has competing frameworks, hidden trade-offs, and uncertain outcomes. this capability forces the agent to reason through them instead of pattern-matching to a confident-sounding answer.

  • 09

    Can the agent still reach a 'wrong' conclusion after passing validation?

    Yes. and that's by design. Critical Thinking Prover validates reasoning PROCESS, not reasoning OUTCOMES. A conclusion can be well-reasoned and still turn out wrong. that's the nature of complex problems. What the capability guarantees is that the reasoning considered assumptions, multiple perspectives, counterevidence, consequences, and uncertainty bounds. A well-structured wrong answer is infinitely more useful than a confidently stated right one. because you can see WHERE the reasoning might break.
