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

3 capabilities in this set.

Part of 3 available through Outbound Network Firewall Validator.

  1. 01

    Validate outbound request

    Checks a specific outbound URL against your defined security policies to ensure it is safe to call.

  2. 02

    Check domain membership

    Verifies if a given hostname is part of your authorized domain allowlist.

  3. 03

    Evaluate ip risk

    Analyzes an IPv4 address to determine if it poses a security risk based on its range.

Real work

What teams actually run

01

Agent Sandboxing

You run an agent in a production environment and need to ensure it only talks to approved APIs.

02

Internal Network Protection

You prevent an agent from scanning or accessing your local database or management consoles.

03

Data Leakage Prevention

You stop an agent from sending sensitive information to an unapproved third-party domain.

04

Compliance Enforcement

You maintain a strict audit trail of allowed network egress for security audits.

One connector, every AI

Outbound Network Firewall Validator 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 Outbound Network Firewall Validator 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 Outbound Network Firewall Validator, so you can see the experience inside your AI.

It does not authenticate your account with Outbound Network Firewall Validator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Outbound Network Firewall Validator owners ask.

  • 01

    What is this MCP used for?

    It is used to validate outbound network requests to prevent unauthorized data egress and SSRF attacks.

  • 02

    How does it prevent SSRF?

    It blocks requests to private IP ranges, preventing agents from reaching internal infrastructure.

  • 03

    Which AI clients can use this?

    You can use this with any MCP-compatible client like Claude, Cursor, or Windsurf.

  • 04

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately.

  • 05

    Can I restrict requests to specific domains?

    Yes, the MCP uses an allowlist to ensure requests only go to authorized hostnames.

  • 06

    Can I use it for subdomains?

    Yes, if you allow mysite.org, then api.mysite.org is also authorized via suffix matching.

  • 07

    What happens if a URL is invalid?

    The validate_outbound_request capability will return an error state and the reason for failure.
