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

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.

The bottom line is: it turns complex email research into simple conversation commands for your AI client.
Subscribe to this MCP and paste your Hunter API Key into the client configuration.

The MCP runs the search/verification, and your agent presents you with actionable data, such as confirmed deliverable addresses ready to save.
Who is this actually for?
This MCP is built for sales and marketing professionals who spend too much time guessing emails or manually updating prospect lists. If you're tired of sending outreach to bounce-back addresses, this tool gives you the certainty you need to actually hit your quota.
They use it daily to find decision-maker emails by searching domains and verifying them before passing qualified leads to Account Executives.
They connect their agent to discover candidate contact information using just a person's name and company, building out talent pipelines fast.
They use it to build verified email lists for campaigns, enriching old contacts with new data before launching an outreach sequence.
What Changes When You Connect
Stop guessing emails. Use verify_email_address to check deliverability on the fly; you know your outreach efforts won't hit a bounce-back folder.
Build massive lists quickly. Running search_domain_emails gives you every professional email associated with a company, not just the obvious ones.
Avoid manual data entry. After finding an email, use enrich_email_data to grab job titles and social profiles in one step.
Keep your database clean. Use tools like list_lead_folders and create_new_lead to organize every prospect into the right place immediately.
Manage credits easily. Check your account status with get_account_usage so you never get stuck mid-campaign due to running out of searches.
See it in action
Cold outreach campaign setup
A B2B marketer needs 50 emails for a new target list. They ask their agent first to use get_domain_email_count on the domain, then run search_domain_emails to gather all possible contacts. Next, they feed those into enrich_email_data and finally save them all using create_new_lead.
Targeting a single decision-maker
A recruiter finds a company name and a VP's name. They ask the agent to run find_person_email. Once an email is generated, they immediately use verify_email_address before sharing it with the candidate.
Cleaning up stale leads
The sales team has 100 old records. They ask the agent to run list_saved_leads, spot outdated contacts, and use get_lead_details to check if they still match current company info before updating them with update_lead_info.
Checking account readiness
Before starting a big search, the SDR asks the agent to run get_account_usage. This confirms they have enough credits remaining for both searches and verifications, preventing workflow stoppage.
The honest tradeoffs
Only searching by company name
An agent just asks to 'find emails at the company.' This is too vague; it doesn't specify if you want all domains or a person's email.
Be specific. First, use get_domain_email_count for a quick check. Then, run search_domain_emails if you need the whole list, or use find_person_email if you are targeting one individual.
Manually copying and pasting data
Copying an email address into a separate checker tool to see if it's good before saving it. This is slow, repetitive, and prone to human error.
Let your agent handle it. After finding the address, always run verify_email_address immediately in the chat flow. The result tells you if you can use it.
Overwriting lead data blindly
Running an update function without checking what info is actually wrong or missing, potentially losing valuable details.
Always check the record first. Use get_lead_details to review the current state of the lead before asking your agent to execute update_lead_info.
When It Fits, When It Doesn't
Use this MCP if your workflow requires high accuracy when sourcing, verifying, or organizing B2B email contacts. Specifically, you need to move beyond simple directory searches and confirm deliverability. Use it when the goal is building a verified list for outreach campaigns. Don't use it if all you need is general company information; stick to basic data lookups instead. If your only task is writing an internal memo, this MCP adds zero value. But if you are in sales—and you need certainty about those emails—this is what you want.
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.
