What formats does this MCP support?

The MCP handles validation and checks for JSON, XML, CSV, and Protocol Buffers.

How does it help with data loss?

It provides a fidelity score and a detailed breakdown of why specific data might be lost during conversion.

Can I use this with Cursor or Windsurf?

Yes, you can connect this MCP to any compatible client including Claude, Cursor, and Windsurf.

What is a fidelity score?

It is a metric used to quantify how much of the original data's integrity is preserved during the serialization process.

Does this MCP host the data?

Vinkius hosts and manages the MCP, so you only need to connect your client once to start using the capabilities.

How does the capability measure data loss?

The capability calculates a data fidelity score by comparing the original data's depth and type precision against the serialized version. You can use analyze_fidelity_loss to get a detailed breakdown of type, precision, or structure loss.

What formats are supported?

The checker supports JSON, XML, CSV, and PROTOCOL_BUFFERS.

Can I find the best format for my data?

Yes, you can use suggest_optimal_format to receive a recommendation based on your specific priorities like compactness, readability, or strict typing.

Connect Output Serializability Checker to ChatGPT and Claude

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Stop losing data when converting AI outputs to structured formats.

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 Output Serializability Checker.

01
Suggest optimal format
This capability recommends the best target format for your data structure. It looks at complexity and specific requirements to pick the most efficient option.
02
Analyze fidelity loss
This capability provides a breakdown of exactly why data fidelity dropped during a serialization attempt. It helps you understand which specific parts of your data structure were lost.
03
Check serializability
This capability evaluates if a specific dataset can be safely converted into your chosen target format. It catches errors before they hit your database or API.

Real work

What teams actually run

Automated Data Pipelines

Your agent validates that generated JSON can be safely converted to CSV for bulk processing.

API Integration

Verify that an AI's output matches the strict requirements of a Protocol Buffers-based API.

Data Migration

Check if moving data from one format to another will result in significant information loss.

Agentic Workflow Testing

Test how well an agent handles complex, nested data structures before deployment.

One connector, every AI

Output Serializability Checker 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 Output Serializability Checker 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.

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 Output Serializability Checker, so you can see the experience inside your AI.

It does not authenticate your account with Output Serializability Checker. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
