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 connection provides 13 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

The painful way to build a prospect list today

Think about it: you find a name on LinkedIn. You copy that URL into one tab. You search for the company domain in another tab. Then, you have to open your CRM and manually check if they have revenue data. If you want emails, you jump to a third tool. It's constant clicking, copying, pasting, and verifying—and it takes hours just to build a list of 50 names.

With this MCP, the agent handles that sequence for you. You give one prompt—say, 'Give me the full details on Acme Corp.' And you get back a single, compiled record with validated domain info, employee lists, and revenue estimates. It’s not just collecting data; it’s structuring your research instantly.

Discovering Contacts with CUFinder MCP

The manual steps that disappear include the need to jump between domain lookup tools, separate employee directories, and email verifiers. You no longer have to guess if a company's main website is correct or if an address is actually valid.

What changes now is speed and certainty. Instead of spending half a workday manually validating fields across multiple platforms, you get the full, structured intelligence in minutes. It’s about turning research effort into pure action.

What your AI can actually do with this

Need to build out a sales list but spend half the day cross-referencing data across five different tabs? This MCP connects your agent to verified business intelligence. You can discover the primary web domain for any company just by knowing its trade name, then pull detailed metadata like industry and estimated revenue.

Need names? List known employees or target specific decision makers associated with a domain. It even pulls professional contact info from LinkedIn URLs, instantly updating records you'd otherwise have to manually research. By connecting this MCP through Vinkius, your agent handles all that grunt work—retrieving accurate company details and verifying emails in one natural chat flow.

Questions you might have

How does CUFinder MCP find the correct domain for a company? +

It uses the find_domain tool to determine the primary web address using only the company's trade name. This is much better than guessing and ensures your records point to the official site.

What if I need a large list of contacts, how do I use bulk_enrich? +

bulk_enrich lets you process multiple records at once. You feed it a batch of company domains or IDs, and it updates all the necessary fields—revenue, industry, etc.—for every item in that set.

Can I find employee details for an entire list of companies? +

You can use find_employees on a specific company domain to pull key roles and decision makers. For multiple companies, you'll need to run this tool sequentially or use the bulk tools.

Is the email found by find_email guaranteed to work? +

While find_email locates potential addresses, always follow up with the verify_email tool. This secondary check confirms if the address is syntactically correct and likely active before you send anything.

Before I run a tool like `find_phone`, how do I verify my connection status with `check_cufinder_status`? +

You must first call check_cufinder_status. This confirms your API key is active and the MCP can reach CUFinder’s services. A successful response means you're ready to run any data retrieval tool.

If I successfully find an email using `find_email`, should I always follow up with `verify_email`? +

Yes, it's a smart habit. While find_email gives you the address, verify_email checks if that mailbox is active and not a spam trap. This saves time by preventing bounces later.

What specific types of information does `get_company_tech` provide about a business? +

This tool gives you details on the technology stack used by a company, such as their CRM or hosting platforms. It's useful for competitive analysis when targeting businesses based on their infrastructure.

If my attempt to `enrich_linkedin` fails due to rate limits, what is the best workaround? +

Wait a short period and retry the call. For larger projects, consider grouping multiple URLs into a bulk operation or adjusting your workflow to hit the data points in smaller batches.

Can I find the official website for a company via AI? +

Yes! Use the find_company_domain tool and provide the company name. Your agent will return the primary web domain registered for that entity.

How do I see the estimated revenue for a specific company? +

Run the get_company_revenue query and provide the domain. The agent will retrieve the estimated annual revenue range from CUFinder's database.

Is it possible to list employees for a domain via AI? +

Absolutely. Use the find_company_employees tool. The agent will retrieve a list of known employees and decision makers associated with that specific company domain.
