How do I use No2Bounce with my AI client?

You connect the MCP through Vinkius and provide your No2Bounce API token. Once connected, you can simply ask your agent to validate emails or check task statuses.

Can I validate large lists of emails?

Yes. You can use the validate_bulk capability to submit large lists, which provides a tracking ID to monitor the progress.

What happens if an email is high-risk?

The MCP identifies invalid, disposable, or high-risk addresses so you can remove them before they impact your sender reputation.

Do I need to check the status manually?

No. You can ask your agent to check the status of a specific tracking ID using the get_validation_status capability.

Which AI clients are compatible?

This MCP works with any MCP-compatible client, including Claude, Cursor, and Windsurf.

How do I submit multiple emails for validation at once?

Use the validate_bulk capability and provide an array of email addresses in the emailList parameter. The server will return a trackingId which you can use to check the results.

How can I check if my bulk validation task is finished?

You can use the get_validation_status capability by providing the trackingId received during the submission. It will return the current progress or the final validation results.

Is there a way to prevent sending the same validation request twice?

Yes, when using validate_bulk, you can provide an optional hashkey. This unique string prevents duplicate requests from being processed within a 3-minute window.

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 · 2 capabilities

Capability set01 / 01

01-02

2 capabilities in this set.

Part of 2 available through No2Bounce.

01
Get validation status
This capability checks the current status of a validation task. Use it to pull the final results once your bulk processing is finished.
02
Validate bulk
This capability submits a list of email addresses for verification. It returns a tracking ID so your agent can monitor the progress of large batches.

Real work

What teams actually run

Pre-Campaign Cleaning

An email marketer hands a list of 5,000 contacts to the agent to ensure high deliverability before a blast.

Lead Verification

A sales rep provides a list of scraped leads to the agent to filter out fake or invalid addresses.

Automated Signups

A developer uses the agent to validate user-submitted emails in real-time during a registration process.

Database Maintenance

A data manager uses the agent to periodically check existing lists for newly identified invalid addresses.

Automate a task

Put No2Bounce to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

No2Bounce 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 No2Bounce 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 No2Bounce, so you can see the experience inside your AI.

It does not authenticate your account with No2Bounce. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
