Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account Br0ski777 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A remote, pay-per-call email finder that lets an assistant guess a person's professional email address from their name and company domain.

What you can do: Find a person's likely professional email from first name, last name and company domain, returned with a confidence score and ranked candidate list after testing 15+ patterns against MX records.
When to use it: Useful for sales outreach, cold emailing or building prospect contact lists when you only know a person's name and company domain and want a likely work email.
Requirements: A remote MCP endpoint; no API key or signup. Each call is paid per use via x402 in USDC on Base L2, so an x402-capable client and a funded wallet are needed.

Before you install

Every lookup costs money (about $0.012 per call) and is settled in USDC on Base; the wallet signs payments automatically. Names and company domains are sent to a third-party service, and results are guesses with confidence scores, not verified addresses.

Installation

In SourceWeft

Open Email Finder API in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Femail-finder/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
