Works with 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 server provides 8 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Finding a vetted prospect email shouldn't require juggling three different tabs.
Today, finding reliable contact data means starting with LinkedIn, then switching to Google Maps for the company address, and finally using an external tool just to check if that person’s name actually correlates to a valid email pattern. It's a mess of copy-pasting and cross-referencing—a massive time sink.
With this MCP server, you simply ask your agent: 'Find me the decision-maker at Acme Corp.' The agent uses `email_finder` to hit multiple data points simultaneously, returning not just an email address, but also a confidence score. That's all you get; no tabs, no jumping around.
Snov.io MCP Server: Automate Prospect List Building
The old way was manually finding 10 domains, running them through a separate checker tool, compiling the results into a spreadsheet, and then manually updating that list with any found emails—a process prone to human error and endless coffee breaks.
Now, you let your agent manage it. You run `domain_search` on 50 targets, get those contacts back, and use `add_prospect` to automatically populate a master list in the background. The entire pipeline runs conversationally, giving you structured data instantly.
What you can do with this MCP connector
Snov.io MCP Server: Your AI Agent's Direct Line to B2B Sales Data
Stop opening dashboards and copying/pasting data into your CRM. You need high-confidence contact details now, and this setup gives your agent direct, conversational access to Snov.io’s full sales automation suite. It’s pure data mining for SDRs who work fast and need validated prospect lists without ever leaving their chat window.
Finding the Emails
Your AI client can find professional emails using a few specific tools. If you're starting with a whole company, run domain_search. This tool searches an entire domain name and reports on potential email patterns and contacts associated with it. If you know something more specific—like a person’s name or a company name—you use email_finder to narrow the search down by inputting that specific domain, name, or company detail.
Verifying & Deep-Diving Prospects
The most critical step is knowing if an email actually works. You can pass any list of addresses through email_verifier. This checks if those provided emails are valid and actively deliverable right now; it prevents the nasty bounces that wreck your sender score. If you already have a known address, you don't have to guess what else might be attached to it.
Run get_prospect_by_email with any single email, and your agent fetches all available prospect details associated with that one address.
Building & Managing Lists
Once you've found and verified contacts, you need to organize them. Your agent can first show you the names and IDs of every existing list using list_prospect_lists. After that, it adds a new, validated prospect record directly into your managed list via add_prospect. This keeps everything clean and structured for targeted campaigns.
Analyzing Companies & Infrastructure
Before you send out anything, you might want to know if the company is even operational. You can run tech_checker on a domain name; this checks its technical infrastructure and reports on details like web servers or CDN usage. For quick account management, use get_balance to retrieve your current remaining credit balance for the service.
Workflow Summary
Your agent handles these steps conversationally. You tell it what you need—find emails, check addresses, build a list, or analyze a domain—and it executes the right tool instantly. It’s designed so you don't have to switch contexts; your AI client does all the heavy lifting for finding and verifying B2B contact data.

How Snov.io MCP Works
- 1 First, you subscribe to the Snov.io integration on Vinkius and get your API credentials.
- 2 Next, you prompt your AI agent with a specific task—like 'Find all emails for AcmeCorp' or 'Verify this list of 50 contacts.'
- 3 Finally, the agent calls the necessary tool (e.g.,
email_finderoremail_verifier), processes the data, and returns the clean, actionable results to you.
The bottom line is: your AI client acts as a conversational API wrapper, turning complex outreach tasks into simple prompts.
Who Is Snov.io MCP For?
SDRs and B2B growth specialists. You're the person who wakes up tired of sending cold emails that bounce because you found an old contact list. Your pain point is data quality; manual research takes too long, and relying on basic public search tools gets you garbage. This gives your agent the firepower to vet leads instantly.
Uses email_finder and tech_checker to validate decision-maker emails before running initial outreach sequences.
Builds highly targeted prospect lists using domain_search and add_prospect, automating the setup for drip campaigns.
Manages small, high-volume lead qualification jobs; they rely on email_verifier to protect client sender reputations while finding leads by domain.
What Changes When You Connect
- Stop guessing if an email address is active. Use
email_verifierto check deliverability on any list, protecting your sender reputation before you hit send. - Build entire outreach funnels from scratch. Your agent can use
domain_searchto find patterns, thenadd_prospectandlist_prospect_liststo keep everything organized. - Get deep intel beyond just the email. The
tech_checkertool confirms if a company's domain is actually operational—that’s key for vetting leads. - Eliminate repetitive data retrieval steps. Instead of manually searching, ask your agent to run
get_prospect_by_email, and it pulls all known details in one go. - Save credits before you start. Always check the balance using
get_balancefirst; that prevents workflow interruptions when running large campaigns.
Real-World Use Cases
Need to warm up a list of leads?
You have 50 domains but no emails. You prompt your agent: 'Find emails for these five companies.' The agent uses email_finder on each domain, builds a preliminary set, and then runs the whole group through email_verifier. Result: A clean list of verified contacts ready for the first wave of outreach.
Building out an account-based marketing (ABM) target list.
You need to find every decision-maker at a specific industry group. You ask your agent to run domain_search across 10 domains, then use the results in add_prospect. The system compiles all data into one master list that you can export and manage.
Vetting a competitor's website.
You want to know if a target company is legit. You ask your agent to run tech_checker on their domain. The agent returns technical details (e.g., specific CDN or web platform), allowing you to confirm their operational depth before wasting time writing copy.
Cross-referencing a single contact's history.
You just got an email for 'Jane Doe.' Instead of searching manually, you tell your agent: 'Get all data for Jane Doe at this address.' The agent uses get_prospect_by_email and pulls every known historical record about her from Snov.io.
The Tradeoffs
Using public search engines (Google)
Searching Google for 'emails at company.com' results in a mix of press releases, old articles, and random contacts—it’s unstructured garbage that needs hours of manual filtering.
→
Use email_finder directly via your agent. It uses structured domain data to pull specific email patterns (like {first}.{last}@domain.com), giving you high-confidence results in seconds.
Sending emails from unverified lists
You copy a list of 100 addresses from an old CRM export and blast them out. Half bounce, half are marked as spam bounces, instantly damaging your sender score.
→
Always run the full batch through email_verifier first. This filters out non-existent mailboxes (like those with a '550 error') so you only send to live inboxes.
Assuming domain activity
A company has a website, but it could be a throwaway site. You spend time writing an email campaign based on poor data.
→
Before outreach, run tech_checker to validate the domain's technical stack and presence. This confirms if they are running a modern, active web infrastructure.
When It Fits, When It Doesn't
Use this server if your job requires deep B2B lead qualification—meaning you need more than just a name and an email address; you need confidence scores, domain technology data, and verified list management. If you are building out outreach sequences for SaaS, finance, or tech, this is necessary.
Don't use it if all you need is to check five contacts quickly. For simple, one-off tasks, basic CRM extensions might be enough. But if your workflow requires vetting the source of the data (tech stack), managing large lists (list_prospect_lists), or confirming deliverability at scale (email_verifier), this suite is essential.
Common Questions About Snov.io MCP
How do I check my usage limits with Snov.io MCP Server? +
You run the get_balance tool to see your current credit count. This is useful before running large searches, so you never get stalled mid-campaign.
Can I find emails for a whole domain using email_finder? +
Yes, that's exactly what the email_finder tool does. You just provide the domain name (e.g., examplecorp.com), and it returns patterns and potential contacts.
What is the difference between adding a prospect and listing them? +
You use add_prospect to input a single, new record into your system. You use list_prospect_lists to see what existing containers of data you've already built.
Does tech_checker only tell me about the website? +
No. The tech_checker tool analyzes the domain's underlying technology—things like CDNs, web servers, and infrastructure—giving a deeper read on the company’s technical setup.
Should I use email_verifier before sending emails? +
Absolutely. You must run email_verifier to clean your list. It prevents bounces by confirming if addresses are currently deliverable, saving you money and protecting your sender score.
How does `get_prospect_by_email` help if I already have a contact's email? +
It pulls the full profile data associated with that specific address. Your agent gets more context than just knowing the email is valid, letting you pull company size or role details.
Should I use `list_prospect_lists` before running `add_prospect`? +
Yes, check existing list names first. This confirms the correct List ID your agent needs to use when adding a new prospect record.
When should I use `domain_search` instead of `email_finder`? +
Use domain_search when you need to map the overall technology stack or infrastructure of an entire domain. If your goal is only finding individual emails, stick with the email_finder tool.
How do I get my Snov.io API credentials? +
Log in to your Snov.io account at app.snov.io. Click your profile avatar (top right corner). Select the API tab. Your User ID and API Secret are displayed on this page. Copy both values and paste them into the configuration fields below. Free plans include 50 credits/month.
Can I find all emails at a specific company domain? +
Yes. Ask your agent 'Find all emails at acme.com' and it returns a list of verified business emails with names, job titles, confidence scores, and the email pattern used at that domain.
Can I set up drip campaigns through the AI agent? +
Yes. Your agent can create drip campaigns, add recipients, configure follow-up sequences, and monitor delivery statuses — complete email automation from a single conversation.
Does Snov.io have a free plan? +
Yes. Snov.io offers a free trial with 50 credits per month, enough for basic email finding and verification. The API works identically on all plans — credits are the only difference. Upgrade for higher volumes.
