How do I connect my Hunter account?

You just need to provide your Hunter API Key after subscribing to the MCP on Vinkius. Once connected, your AI client can immediately start using the capabilities.

Which AI clients can use this MCP?

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

Can I save leads directly to my CRM?

Yes, you can tell your agent to create new leads or add them to specific folders in your Hunter CRM.

Does this verify if an email is real?

Yes, the verify_email_address capability checks the deliverability of an address and provides a confidence score.

How can I see how many credits I have left?

You can simply ask your agent to check your account usage, and it will report your remaining search and verification credits.

Can I find all professional email addresses for a specific company?

Yes. Use search_domain_emails with a domain (e.g., 'stripe.com') or company name (e.g., 'Stripe') to retrieve all professional emails found for that organization. Each result includes the email, confidence score, position, and source URLs. Use get_domain_email_count to preview how many emails are available before using search credits.

Can I verify if an email address is valid before sending outreach?

Yes. The verify_email_address capability checks the validity and deliverability of any email address. It returns a status (deliverable, undeliverable, risky, unknown), confidence score, and details about the email server (MX records, SMTP check, accept-all detection). This prevents bounces and protects your sender reputation.

How does Hunter API authentication work?

Hunter uses an API Key passed as a query parameter (?api_key=YOUR_KEY) in all requests to api.hunter.io/v2. This differs from the typical Bearer token pattern. Your API key is available in the Hunter dashboard under Account > API. Free accounts include 25 searches and 50 verifications per month.

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.

Automate a task

Put Hunter 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

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

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