Email Finder MCP Server: Find & Verify Work Emails from Claude, Cursor

Scrupp email finder MCP in one paragraph

Scrupp runs an MCP server that finds a work email from a name and a company domain and verifies addresses you already have. Add it to Claude as a connector at https://mcp.scrupp.com/mcp, or run npx -y scrupp-mcp-server in Cursor or any MCP client. It is listed in the official MCP registry. You pay only for emails found; a work email comes back for 36.3% of rows.

Email tools

Find emails: work email from first name, last name and company domain, one person or a list.
Verify emails: a deliverability check for addresses you already have, before you send.
Job status and credit balance, so the assistant can collect a long job and tell you what is left.

With the full tool set

Export a Sales Navigator, LinkedIn or Apollo search with work emails.
Find decision makers at a company you know only by domain or name.
Look up a company, or enrich a list of LinkedIn profiles.

LinkedIn searches use your LinkedIn account connected to Scrupp with the Chrome extension; on paid plans they can also run on Scrupp's shared account capacity. Email finding needs no LinkedIn at all.

Measured, not promised

How often it finds an email, and what it costs

The server uses the same email finder as the Scrupp app. Measured across all exports, an address comes back for 36.3% of rows and 10.0% are confirmed by an accepted delivery.

It spends the same credits as the app and the API: a lookup is charged only when an email is found, and verifying an address costs 1 credit. The free plan gives 100 credits a month with no credit card; paid plans are on the pricing page.

Questions about the email finder MCP

What is an email finder MCP server?

An MCP (Model Context Protocol) server gives an AI assistant tools it can call. Scrupp's server lets Claude, Cursor or another MCP client find a person's work email from their name and company domain, and check an address before you send to it, inside the conversation.

How do I add Scrupp to Claude?

In Claude.ai or Claude Desktop open Settings, then Connectors, choose Add custom connector and paste https://mcp.scrupp.com/mcp for emails only, or https://mcp.scrupp.com/sn for the full tool set. Press Connect and sign in to Scrupp; there is no API key to copy.

How do I use it in Cursor or another MCP client?

Add a server that runs npx -y scrupp-mcp-server with your Scrupp API key in the SCRUPP_API_KEY variable. The package is on npm as scrupp-mcp-server and in the official MCP registry as io.github.wismhero-maker/scrupp.

How much does it cost?

The same credits as the Scrupp app and API. Finding an email is charged only when an email is found; verifying an address you already have costs 1 credit. The free plan gives 100 credits a month with no credit card.

How often does it find an email?

Measured across all Scrupp exports, a work email comes back for 36.3% of rows, and 10.0% are confirmed by an accepted delivery. The share differs from one list to another, so try it on your own list first.

Does it send emails or automate LinkedIn?

No. The MCP server has no tool that sends email, and it never sends connection requests or LinkedIn messages. It finds and checks addresses and exports lists; you send from the sequencer you already use.
