What kind of breaking changes does this MCP detect?

It detects field deletions, type mutations, and changes in field nullability.

How do I use this with my AI client?

You connect your client to Vinkius once, and then you can give your agent instructions to use the capabilities directly.

Does it work with any GraphQL SDL?

Yes, as long as the SDL is syntactically valid, the capability can process and compare it.

Can I check if my schema is valid without comparing it?

Yes, you can use the validate_syntax capability to check for structural correctness alone.

Do I need to host the MCP myself?

No, Vinkius hosts and manages the MCP so it is ready to use immediately upon connection.

What constitutes a breaking change in this capability?

A breaking change is any modification that violates the existing contract, such as removing a type or field, changing an argument, or transitioning a field from nullable to non-null.

Can I use this to verify my new schema before deployment?

Yes, by using compare_schemas with your current production schema as the base and your proposed changes as the next version, you can identify all potential regressions.

Does it support all GraphQL features?

The capability parses and compares types, fields, arguments, and enums. It specifically monitors nullability constraints and type mutations.

Connect GraphQL Schema Breaking Change Detector 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 breaking your API clients with unexpected schema changes.

Waiting for input…

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 GraphQL Schema Breaking Change Detector.

01
Inspect schema
This capability reveals the internal structure of your GraphQL types and fields. Your agent uses it to map out the parsed schema for deeper analysis.
02
Validate syntax
This capability checks your GraphQL SDL for structural correctness. It ensures the schema is valid before you attempt any comparisons.
03
Compare schemas
This capability identifies breaking changes by comparing two different GraphQL schemas. It flags deletions, type changes, and nullability shifts.

Real work

What teams actually run

CI/CD Integration

Your agent can check a proposed schema change against the current production schema to block breaking updates.

Refactoring Verification

Verify that renaming or changing a type doesn't inadvertently break existing field definitions.

Schema Auditing

Use the inspection capability to get a clear view of the current type hierarchy.

Regression Testing

Compare a new schema version against a known baseline to find unexpected deletions.

One connector, every AI

GraphQL Schema Breaking Change Detector 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 GraphQL Schema Breaking Change Detector 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 GraphQL Schema Breaking Change Detector, so you can see the experience inside your AI.

It does not authenticate your account with GraphQL Schema Breaking Change Detector. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
