What can this MCP validate in my .env files?

It validates structural integrity, data type accuracy, and security hygiene, such as checking for exposed secrets or unused variables.

Which AI clients can I use with this MCP?

You can use this MCP with any compatible client, including Claude, Cursor, Windsurf, and VS Code.

How does it help with security?

The audit capability identifies potential security risks like secret exposure and helps you find unused variables that clutter your configuration.

No, Vinkius hosts and manages the MCP for you. You just connect your client and start using the capabilities.

How can I check if my .env file is missing any required keys?

You can use the validate_env_structure capability by providing your .env content and a list of the keys that must be present.

Can this capability detect if I accidentally committed an API key?

Yes, the audit_config_health capability performs heuristic pattern matching to identify potential secret exposure in your configuration values.

How do I verify that my numeric variables are actually numbers?

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 · 3 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Env Variable Config Validator.

01
Audit config health
This capability scans your .env file for security risks and identifies any unused variables. It helps you find exposed secrets or dead config entries that should be removed.
02
Validate env structure
This capability checks the structural integrity of your .env files. It ensures all required keys are present and identifies duplicate definitions.
03
Verify data integrity
This capability enforces type constraints on your environment values. It verifies that variables match their expected types, such as ensuring a port is a number.

Real work

What teams actually run

Pre-deployment Audits

Run a full health check on your production environment variables before pushing code.

Local Development Setup

Ensure your local .env file matches the expected structure of the application.

Security Scanning

Use the agent to scan for accidentally committed secrets or sensitive data in config files.

Config Cleanup

Identify and remove old, unused variables that have accumulated in your environment files.

One connector, every AI

Env Variable Config 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 Env Variable Config 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 Env Variable Config Validator, so you can see the experience inside your AI.

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