UK Data: Email and domain checks

Overview

UK Data: Email and domain checks is a Model Context Protocol server that validates email addresses and domains through multiple verification methods. It checks whether addresses are deliverable, identifies disposable and role-based accounts, and retrieves MX records, SPF, and DMARC configuration data. By exposing these capabilities as MCP tools, the server lets AI assistants perform email and domain validation programmatically without leaving your workflow.

The server runs as a remote endpoint at https://ukdata.reliness.co.uk/mcp/email-domain. You authenticate using an API Key and require no local installation—simply configure your MCP client to connect to the hosted service. The latest release is v1.4.0.
