What you can do
  • Verify a single email address: syntax check, MX record lookup, disposable-domain and role-address detection, and a 0-100 quality score
  • Check service health, which returns status, price and network without charge
When to use it
Useful when an assistant needs to screen email addresses before signup, outreach or list cleaning, and the workflow can tolerate a small per-call crypto payment.
Requirements
A remote streamable HTTP endpoint; no package, environment variable or header is declared. Calls to the verification tool cost $0.001 USDC each via x402, so a wallet or x402-capable client able to pay on the stated network is needed.
Before you install
The verification tool is paid: $0.001 USDC per call, so repeated use spends real funds. Email addresses submitted for verification are sent to a third-party hosted service. No authentication is declared, so payment handling is the main control point.

Installation

In SourceWeft

  1. Open x402 Email Verifier 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/dev.workers.microtools-x402.x402-email-verifier%2Femail-verifier/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.

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.
