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 · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

One connector, every AI

Business Logic Gatekeeper 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 Business Logic Gatekeeper 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 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 Business Logic Gatekeeper, so you can see the experience inside your AI.

It does not authenticate your account with Business Logic Gatekeeper. 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 Business Logic Gatekeeper owners hand off.

This MCP is built for engineering teams who need to automate the enforcement of business-critical logic.

  • 01

    Backend Engineers

    They use the MCP to ensure new logic doesn't break existing financial or security invariants.

  • 02

    DevOps Engineers

    They implement these rules to maintain system integrity during continuous deployment.

  • 03

    Software Architects

    They define the core business rules that the AI agent must enforce across the codebase.

FAQ

Questions Business Logic Gatekeeper owners ask.

  • 01

    How does the MCP validate code?

    It uses regex-based validation to check if code changes adhere to the business rules you have registered.

  • 02

    What clients can I use with this MCP?

    You can connect it to any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

  • 03

    Can I add new rules at any time?

    Yes, you can use the register_rule capability to add new business rules or invariants to the registry whenever needed.

  • 04

    Does this replace unit testing?

    No, this is a different layer of defense that focuses on business logic invariants rather than functional code execution.

  • 05

    Where are the rules stored?

    The rules are managed within the gatekeeper's registry, which you can query at any time.

  • 06

    How does the gatekeeper validate code?

    It uses the check_compliance capability to match file contents against registered validationRegex patterns defined in business rules.

  • 07

    Can I add custom business rules?

    Yes, you can use the register_rule capability to add new invariants with specific severity levels and affected file paths.

  • 08

    What is a compliance score?

    The compliance score is a value between 0 and 1 representing the ratio of satisfied rules to total applicable rules.
