Built on the Model Context Protocol (MCP) for Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 12 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Finding and validating contacts used to be a painful, manual process., Solved with Vinkius AI Gateway

Today, finding accurate professional email addresses means spending hours on LinkedIn, cross-referencing company websites, and then running those emails through separate verification tools. You collect lists of domains, guess the correct format for names, and then manually check each address one by one to see if it bounces or if it's even active.

With this MCP, you just talk to your agent. You tell it a domain or a person's name. It handles the whole sequence—it finds all possible emails, verifies them against deliverability standards, and presents only the addresses that are safe for outreach. The entire messy process shrinks down to one conversation.

The Hunter MCP gives you confirmed, ready-to-use contact data.

You eliminate the need to switch between domain search tools, dedicated email finders, and separate CRM list managers. The ability to run `search_domain_emails` and then immediately use `enrich_email_data` on those results keeps your workflow contained.

This means you spend less time debugging data sources and more time actually talking to prospects. It's not just finding emails; it’s getting actionable, verified intelligence.

What your AI can actually do with this

Connect this MCP to any AI client—Claude, Cursor, or whatever you use—and let your agent handle email prospecting conversations. Instead of manually guessing emails, you tell your agent what domain you're interested in, and it finds every professional address associated with that company. Need a specific person? Tell it the name and company; it figures out the best guess for their email.

It even checks if that email is deliverable right now, giving you confidence scores so you know which leads are safe to use. When you need to build out your prospect list, this MCP does the heavy lifting, letting you enrich contacts with titles and social profiles, or save them directly into a managed lead list.

You get access to all of this functionality through Vinkius, making it easy for any compatible client to run complex sales workflows without leaving their environment.

Questions you might have

How do I use the Hunter MCP to verify an email address? +

You simply ask your agent to run verify_email_address on the specific email. The result immediately tells you if it's deliverable and provides a confidence score, so you know if it'll make it into the inbox.

Can I find emails for an entire company domain using Hunter MCP? +

Yes. Use search_domain_emails to list every professional email address associated with a full domain name, giving you a comprehensive list of contacts.

What is the best way to save leads after finding them? +

After gathering contact info, use create_new_lead to save it. You can also organize those new records by first listing your folders using list_lead_folders.

Does the Hunter MCP only find emails? Can it get more data? +

No, it gets much more than just emails. Use enrich_email_data to pull in professional context like job titles, company names, and even social media links.

How do I check if I have enough credits for a big campaign? +

Run the get_account_usage tool. This reports your current usage against your plan's limits for both searches and verifications, so you can budget your efforts.

How do I update existing records using the Hunter MCP's lead tools? +

You can modify saved contact details directly via the MCP. The update_lead_info tool lets you correct titles, change company names, or add new data to an established profile without having to create a whole new record.

Can I remove old records using the Hunter MCP's lead tools? +

Yes, you can clean up your CRM data by deleting profiles. Use remove_lead when a stored lead is outdated or incorrect and should no longer be tracked in your list.

How does the Hunter MCP manage my saved lead organization? +

You manage your structure using specific tools. The list_lead_folders tool shows all the organizational categories available, letting you see exactly where your different prospect lists are stored.

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 tool 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.
