How do I use this YAML MCP in Claude?

You connect to Vinkius once, and the capabilities become available in your Claude interface. You can then ask your agent to validate or flatten YAML directly.

Can this MCP find duplicate keys in my YAML?

Yes, the validate_yaml_structure capability is designed to detect duplicate keys and other syntax errors.

What is dot-notation flattening?

It is a way to turn a nested YAML structure into a flat list of keys, such as turning 'user: { name: Alice }' into 'user.name: Alice'.

Does this work with Cursor or Windsurf?

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

Will this help with indentation errors?

Yes, you can use the get_indentation_analysis capability to find specific spacing inconsistencies in your files.

How can I check if my YAML file has indentation errors?

You can use the get_indentation_analysis capability to identify specific line numbers where indentation rules are broken or where tabs and spaces are mixed.

Can I convert nested YAML into a flat list?

Yes, the flatten_yaml_structure capability converts hierarchical YAML into a flat mapping of dot-notation keys and their leaf values.

What happens if the YAML is invalid?

The validate_yaml_structure capability will return a list of specific errors, including the exact line number and a description of the violation.

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 YAML Validator & Flattener.

01
Flatten yaml structure
This capability converts nested YAML hierarchies into a flat list of dot-notation key-value pairs. It makes deep data much easier for your agent to read and manipulate.
02
Validate yaml structure
This capability checks the structural integrity of any YAML string. It identifies syntax errors like duplicate keys or incorrect indentation that would otherwise break your code.
03
Get indentation analysis
This capability inspects the specific spacing patterns within a YAML file. It helps you find subtle inconsistencies in how levels are defined.

Real work

What teams actually run

Config File Cleanup

Your agent scans a messy YAML config to find and fix indentation mistakes.

Data Transformation

You tell your agent to flatten a nested YAML file so it can be used in a simpler format.

CI/CD Pre-checks

Your agent validates the structure of a YAML file before it is committed to a repository.

Schema Compliance

Your agent checks that a YAML file does not contain duplicate keys that violate your requirements.

One connector, every AI

YAML Validator & Flattener 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 YAML Validator & Flattener 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 YAML Validator & Flattener, so you can see the experience inside your AI.

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