Overview

AI-generated overview

Remote MCP server that verifies email deliverability and scores B2B leads A-F before outreach.

What you can do
  • Verify single addresses or batches for deliverability, MX validity, disposable, role and free-mail signals, and domain age
  • Score one B2B lead 0-100 with an A-F grade, supporting signals and a recommendation
  • Score a batch of leads, ranked best-first, with a grade distribution
  • Fetch a curated daily verification-activity brief
  • Read FoundryNet Data Network and MINT cross-promotion information
When to use it
Useful when an assistant needs to check whether email addresses are real and deliverable, or to grade and rank B2B lead lists before spending time on outreach.
Requirements
Remote Streamable HTTP endpoint (legacy SSE also offered); no local install, account or API key is declared. A free tier of 25 queries per day per agent applies, after which paid x402 (USDC on Solana) payment is required; an fnet_ Bearer key is described as bypassing that.
Before you install
Most tools are metered and cost money per lead or per email, with minimums on batch calls and a $5 daily brief; beyond the free tier, payment is made in USDC on Solana, so a wallet and spending are involved. Email addresses and lead data are sent to a third-party service. A paid fnet_ Bearer key is a secret to keep private.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. 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.FoundryNet%2Femail-verify-mcp/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

Other MCP clients

Add this to your client's mcpServers config.
