Overview

AI-generated overview

Local MCP server that lets an assistant look up verified professional email addresses by name, domain, LinkedIn profile, or job role.

What you can do
  • Find a person's email from a name plus company domain
  • Find an email from a LinkedIn profile URL
  • List emails found at a company domain
  • Find a decision maker's email by role and domain
  • Validate whether an email address is deliverable
When to use it
Useful for sales, recruiting, or outreach research where you want an assistant to turn a name, company domain, LinkedIn profile, or job title into a contact email, and to check whether an address is deliverable.
Requirements
Runs locally via npx (Node.js). Requires an API key from the provider's dashboard, supplied in the EMAILFINDER_API_KEY environment variable. Network access to the provider's service is needed.
Before you install
Lookups consume paid credits: 1 credit per person or LinkedIn lookup, 5 per company or decision-maker lookup, charged only when an email is found; validation is free. The API key is a secret and should not be shared. Queries about people and companies are sent to the third-party emailfinder.dev service.

Installation

In SourceWeft

  1. Open Emailfinder Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
