How does this MCP calculate switching costs?

The MCP factors in both the direct financial cost of moving and the impact of the learning curve on your productivity.

Can I use this with Cursor or VS Code?

Yes, this MCP works with any MCP-compatible client including Cursor, VS Code, Claude, and Windsurf.

What is an efficiency score?

It is a calculated metric that represents the operational value of your capabilities relative to their cost and complexity.

Does this MCP host my data?

Vinkius hosts the MCP and manages the connection, but your agent performs the analysis based on the data you provide.

Can it help me find overpriced software?

Yes, the identify_optimization_targets capability specifically scans your stack to flag capabilities that are over-priced.

How does the efficiency score work?

The efficiency score is a composite metric that balances productivity gains against monetary costs and integration complexity.

Can I simulate replacing a capability before I buy it?

Yes, you can use simulate_stack_evolution to predict how efficiency and costs will change if you replace or remove capabilities.

Does it account for the time it takes to learn new software?

Yes, the evaluate_alternative capability specifically includes a parameter for learning curve impact to account for temporary productivity loss.

Waiting for input…

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.

Curated set · 4 capabilities

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Builder Toolstack Optimization.

01
Evaluate alternative
This capability checks if replacing a specific piece of software with a different option actually makes financial sense.
02
Get stack economics
This capability calculates your total monthly software spend and establishes your current efficiency baseline.
03
Identify optimization targets
This capability scans your entire software list to flag capabilities that are overpriced or underperforming.
04
Simulate stack evolution
This capability predicts how your efficiency score will shift if you add, remove, or swap groups of capabilities.

Real work

What teams actually run

Budget Optimization

Identify which software subscriptions to cancel to reduce monthly burn.

Capability Migration Planning

Determine if the cost of moving to a new platform is offset by its long-term value.

Performance Auditing

Find capabilities that are technically underperforming relative to their price tag.

Stack Evolution Modeling

Simulate how a major change in your tech stack will affect your team's productivity.

One connector, every AI

Builder Toolstack Optimization 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 Builder Toolstack Optimization 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 Builder Toolstack Optimization, so you can see the experience inside your AI.

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