Connect WebSocket Event Schema Validator to your AI
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 malformed socket messages from breaking your application logic.
Developed, maintained, and hosted by Vinkius.

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.

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.
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.
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.
01-03
3 capabilities in this set.
Part of 3 available through WebSocket Event Schema Validator.
- 01
Audit schema registry
This capability scans your entire schema registry to find integrity issues. It identifies incomplete or empty definitions that could lead to broken event handling.
- 02
Validate event payload
This capability checks a specific WebSocket event payload against your registry. It catches missing fields or incorrect data types immediately.
- 03
Verify event registration
This capability confirms whether a specific event name is officially recognized in your registry. It prevents the use of unregistered or misspelled event types.
Real work
What teams actually run
Real-time Debugging
You paste a suspicious WebSocket payload into your AI client to see why it failed validation.
Schema Maintenance
You run an audit to find event definitions in your registry that lack structural rules.
Integration Testing
Your agent verifies that a new event type is correctly registered before testing the full data flow.
Data Integrity Monitoring
You use the validator to ensure all incoming messages adhere to the deterministic registry.
One connector, every AI
WebSocket Event Schema 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.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put WebSocket Event Schema 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.

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 WebSocket Event Schema Validator, so you can see the experience inside your AI.
It does not authenticate your account with WebSocket Event Schema Validator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for
Built for the work WebSocket Event Schema Validator owners hand off.
This MCP is built for engineers managing real-time, event-driven systems where data consistency is critical.
- 01
Backend Engineers
They hand off socket payloads to the AI to verify they match the expected backend schema.
- 02
QA Automation Engineers
They use the MCP to validate that event-driven test suites are sending correctly formatted data.
- 03
System Architects
They use the auditing capabilities to ensure the schema registry remains clean and complete.
FAQ
Questions WebSocket Event Schema Validator owners ask.
- 01
What does this MCP actually validate?
It validates the structure, field presence, and data types of WebSocket event payloads against a schema registry.
- 02
Can I use this with Cursor or VS Code?
Yes, you can connect this MCP to any compatible client including Claude, Cursor, Windsurf, and VS Code.
- 03
How does it help with schema errors?
It uses the audit capability to find incomplete or empty definitions within your registry, helping you catch errors early.
- 04
Does it work with Socket.io?
Yes, it is designed to handle event-driven communications including those using Socket.io.
- 05
Do I need to host the MCP myself?
No, Vinkius hosts and manages the MCP for you. You just connect your client and start using the capabilities.
- 06
How does the validator identify which schema to use?
The validate_event_payload capability extracts the event type directly from the provided payload and then performs a lookup in your provided schemaRegistry to find the matching rules.
- 07
Can I use this for Socket.io or native WebSockets?
Yes, it works with any WebSocket-based communication, including Socket.io and native WebSockets, as long as you provide the payload and the corresponding registry.
- 08
What happens if an event is not in my registry?
If the event type found in the payload does not exist in your schemaRegistry, the validator will return unregisteredEvent: true and mark the payload as invalid.
