Server-Side Request Forgery is a vulnerability where an attacker forces a server or agent to make requests to unintended locations, often internal ones.

Which AI clients can use this MCP?

It works with Claude Desktop, Cursor, Windsurf, VS Code, and any other MCP-compatible client.

How does it block internal IPs?

It uses 32-bit integer math to check if an IP address falls within private or loopback ranges.

Does this MCP host the data?

Vinkius hosts and manages the MCP so it is ready to use immediately upon connection.

Can it block file access?

Yes, it validates URL schemes to prevent access to local files through protocols like file://.

How does this capability prevent SSRF attacks?

The validate_url capability checks the URL scheme to ensure it is web-safe and uses bitwise integer math to block any requests targeting private or loopback IP ranges.

Which IP ranges are blocked?

It blocks loopback addresses, Class A, B, and C private networks (10.x.x.x, 172.16.x.x, 192.168.x.x), and 0.0.0.0.

Can I use this with Claude Desktop?

Yes, this MCP server is compatible with Claude Desktop and other MCP-compliant clients via Vinkius Edge.

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.

3 capabilities in this set.

Part of 3 available through URL SSRF Prevention Validator.

01
Check ip safety
This capability checks if a specific IP address falls within a private network range.
02
Parse URL components
This capability breaks a URL down into its individual parts for inspection.
03
Validate URL
This capability performs a full safety check on a URL to ensure it is a safe, public resource.

Real work

What teams actually run

Agentic Web Browsing

Use this when your agent needs to fetch data from the web but shouldn't touch your local network.

Automated Security Auditing

Run your agent through various URLs to see if it correctly identifies and rejects unsafe targets.

Safe Capability Integration

Add this to your AI workflow to validate any URL before passing it to a fetching capability.

Internal Network Protection

Prevent an AI client from being used to scan for open ports on your internal servers.

One connector, every AI

URL SSRF Prevention 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 URL SSRF Prevention 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.

Preview access · not provider authentication

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

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