Does this work in my published apps?

No. Custom MCP connectors are personal chat connectors: they work in your Lovable chat while it builds for you, but visitors can't reach the tool through your published app.

If I connect API Contract Diff Checker to Gemini, can I use the same connection in Claude or ChatGPT later?

Yes, and that's the point: the connection is yours, not Gemini's. You paste the same link in any AI you use, and there's nothing new to set up or pay again. Connect a new AI and API Contract Diff Checker is already there.

What does Lovable need to connect to API Contract Diff Checker?

Just the link. Choose No authentication as the auth option, because the hosted Connector handles access on our side. If you prefer OAuth, pick it and you'll be prompted to authorize.

What can I actually ask Gemini to do with API Contract Diff Checker?

Whatever the Connector covers: check data, run actions and bring answers back. The Connector page lists every capability your AI gains, with real examples you can copy.

Gemini doesn't show the Connector. What do I check?

Make sure the Server URL was pasted exactly as copied and the connector is authorized, then confirm the Connector is active in your Vinkius account. A deactivated Connector stops responding.

Can I remove the access later?

Remove the connector in Connectors and it's out of your chats. Your Vinkius account keeps the connection and its history either way, ready for the next AI.

Lovable + API Contract Diff Checker

One chat. Your API Contract Diff Checker, live inside Lovable.

Real prompts, answered with live data. This is the kind of conversation you will have in Lovable once the connector is in.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

These prompts ship with the API Contract Diff Checker Connector. Once yours is connected, they work in your sessions.

The full capability set, the prompts and the observed latency live on the API Contract Diff Checker Connector page.

Mission Control

See everything your Lovable agents do in API Contract Diff Checker.

When Lovable runs a tool in API Contract Diff Checker, it happens on Lovable's side: you see the result in the chat, but not the request itself, what data it carried, or whether a rule was broken.

Now every move lands on your screen.

Every execution is recorded, enforced, and shown to you: what ran, what it returned, what was blocked, and why.

Request Volume & Latency

requests latency

Every request your Lovable agents make through API Contract Diff Checker is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your API Contract Diff Checker workflows.

What sets us apart

It's not just the Connector that stays safe. Everything your agents do through it is.

Connecting API Contract Diff Checker to your AI is step one. But an open line between your agents and API Contract Diff Checker is only half the story: without protection, every action they take runs unguarded.

That's why protection doesn't stop at the door.

Every action your agents take through the Connector runs inside our infrastructure: signed activity logs, automatic key rotation, spending limits that pause instead of surprise, and a sandbox that isolates every execution.

Tamper Proof Activity Log

Every request your agents make in API Contract Diff Checker is recorded and signed, so any change to the history becomes detectable.

Automatic Key Rotation

We rotate security keys every 24 hours. Your API Contract Diff Checker connection stays protected without any manual work.

Spending Protection

We enforce the spending limit you choose and pause actions that exceed it until approval is received. Your API Contract Diff Checker actions never surprise you.

Isolated Sandbox

Every execution through API Contract Diff Checker runs isolated, with 34+ security rules covering memory, CPU, network access, file handling and execution.

Security Event Streaming

Security events flow to Splunk, Datadog or your own webhook, so API Contract Diff Checker activity lands in the tools you already rely on.

Instant Resume

Idle connections resume in 3 to 5 ms while preserving their state, keeping your Lovable sessions responsive.

Malicious File Protection

We detect compressed files designed to exhaust system resources and block them before they ever reach API Contract Diff Checker.

Credential Validation

We test your API Contract Diff Checker credentials before saving them. Invalid credentials are rejected instead of being stored.

Separate Usage Limits

Usage stays isolated per account, so activity in one connection never consumes another account's allowance.

One Connector, one link, and the whole operation is protected. Not just the connection: everything your agents do through it.

These guarantees are not add-ons: they are the infrastructure every API Contract Diff Checker connection runs on. Read how our infrastructure protects everything your Lovable agents do, end to end.
