ValidKit Email Validation is a Model Context Protocol (MCP) server that integrates the ValidKit email validation API into AI assistants like Claude Code, Cursor, Windsurf, and Claude Desktop. It performs syntax checks, MX record verification, disposable email detection, and typo suggestions directly from the editor.
Install by adding the server configuration to your MCP client (Claude Code, Cursor, Windsurf, or Claude Desktop) using npx -y @validkit/mcp-server and setting the VALIDKIT_API_KEY environment variable. Invoke tools like validate_email, validate_emails_bulk, or check_usage via natural language commands.
It checks email syntax, DNS records, MX server existence, and detects disposable, role‑based, and free email addresses. It also suggests typo corrections.
Node.js is required to run the server via `npx`. A ValidKit API key is mandatory; sign up at validkit.com/get-started for a free tier with 1,000 validations per month.
Email addresses are sent to the ValidKit API (default: `https://api.validkit.com`) for validation. No data is stored locally by the MCP server.
The free plan includes 1,000 validations per month. The `validate_emails_bulk` tool accepts up to 1,000 emails per request. Rate limits apply per API key.
The server runs locally via stdio transport using `npx`. Authentication is handled by the `VALIDKIT_API_KEY` environment variable. No additional auth mechanisms are required.

Official Mobile Text Alerts server. Send and schedule SMS, manage subscribers and groups, and complete carrier registration from any MCP-compatible AI assistant.

Nitrosend's official remote MCP server. Your agent drafts campaigns, builds automation flows, segments contacts and sends transactional email from Claude, ChatGPT, Cursor or Codex. OAuth sign-in, free plan.

Email for long-term client relationships: ARVX reads each person first and remembers every pair.
Local MCP server for Thunderbird. Gives Claude Desktop, Cursor, or any MCP client read/write access to multiple mailboxes, calendars, contacts, notes & tasks (Gmail, Outlook, IMAP) — all on your machine.
