What is an opportunity cost?

It is the value of the next best alternative you give up when you make a choice. It is not just about money, but also time, resources, and future flexibility.

How does this MCP prevent AI tunnel vision?

It uses a 6-pivot structure that requires the agent to explicitly name a discarded alternative and quantify the cost of that rejection.

Can I use this with Cursor or Windsurf?

Yes, this MCP is compatible with any MCP-compatible client including Claude, Cursor, and Windsurf.

What happens if the AI's math is wrong?

The capability will return a verdict that rejects the decision, forcing the agent to fix the logic or the calculation before proceeding.

Does this work for non-technical decisions?

Yes, the logic applies to any domain, from engineering and software design to career moves and financial investments.

Why can't 'doing nothing' be the discarded alternative?

Because comparing a solution against 'doing nothing' is a false dichotomy used to artificially inflate the value of the solution. The engine forces the AI to compare its idea against the next best active technical strategy.

Why does the prover require an irreversible tradeoff analysis?

Because decisions are classified into two categories: type-1 (irreversible, one-way doors) and type-2 (reversible, two-way doors). If an AI suggests a type-1 decision without acknowledging its permanent nature (e.g. schema changes, switching databases), it creates technical debt that cannot be undone.

What does 'quantify lost opportunities' mean in practice?

It means assigning a concrete cost (such as engineering velocity, infrastructure costs, or latency) to what you lose by choosing the path. For example, choosing custom development instead of a SaaS integration has an opportunity cost of slower time-to-market.

Connect Opportunity Cost Prover to ChatGPT and Claude

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Stop your AI from making one-sided decisions.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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.

Capability set01 / 01

1 capability in this set.

Part of 1 available through Opportunity Cost Prover.

01
Validate opportunity cost
This capability forces a structured reflection on any major decision by requiring six specific pivots: chosen path, discarded alternative, direct cost, opportunity cost, irreversibility, and math verification. It rejects any analysis that lacks a concrete alternative or fails to prove that gains outweigh the total costs.

Real work

What teams actually run

Cloud Architecture

Comparing serverless functions against containerized clusters to weigh latency against maintenance savings.

Resource Allocation

Deciding whether to hire a new specialist or invest that budget into marketing or R&D.

Strategic Planning

Evaluating a new market entry by calculating the lost revenue from focusing on existing products.

Capital Investment

Analyzing if buying new equipment provides more value than investing the same cash into a high-yield account.

Automate a task

Put Opportunity Cost 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

Opportunity Cost 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 Opportunity Cost 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.

Preview access · not provider authentication

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

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