Does this work in the Gemini web and mobile apps?

Not yet. The Gemini apps use built-in Connected Apps that you toggle on and off, and they don't accept custom Connector links today. The supported path is the free Gemini CLI, where the same link runs Braintrust in your terminal.

If I connect Braintrust 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 Braintrust is already there.

Do I need to hand my Braintrust password to Gemini?

Never. You sign in once at Vinkius, and we keep your logins encrypted and away from your AI. Gemini only ever sees the link, and you can remove it whenever you want.

What can I actually ask Gemini to do with Braintrust?

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?

Run gemini mcp list and check that the status shows CONNECTED, confirm the Connector is active in your Vinkius account, then run the add command again if needed. A deactivated Connector stops responding.

Can I remove the access later?

Anytime. Run gemini mcp remove and it's out of your terminal. Your Vinkius account keeps the connection and its history either way, ready for the next AI.

How to give Gemini access to Braintrust

Gemini + Braintrust

One chat. Your Braintrust, live inside Gemini.

Real prompts, answered with live data. This is the kind of conversation you will have in the Gemini CLI once the link is in.

Waiting for input…

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

These prompts ship with the Braintrust Connector. Once yours is connected, they work in your sessions.

The full capability set, the prompts and the observed latency live on the Braintrust Connector page.

Mission Control

See everything your Gemini agents do in Braintrust.

When Gemini runs a tool in Braintrust, it happens in the terminal: you see the result, 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 Gemini agents make through Braintrust is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your Braintrust workflows.

What sets us apart

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

Connecting Braintrust to your AI is step one. But an open line between your agents and Braintrust 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 Braintrust is recorded and signed, so any change to the history becomes detectable.

Automatic Key Rotation

We rotate security keys every 24 hours. Your Braintrust 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 Braintrust actions never surprise you.

Isolated Sandbox

Every execution through Braintrust 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 Braintrust 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 Gemini sessions responsive.

Malicious File Protection

We detect compressed files designed to exhaust system resources and block them before they ever reach Braintrust.

Credential Validation

We test your Braintrust 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 Braintrust connection runs on. Read how our infrastructure protects everything your Gemini agents do, end to end.
