Description
The Resend MCP Server is Resend's official Model Context Protocol integration, letting AI assistants send and receive transactional email, manage contacts, broadcasts, and domains directly from Claude, Cursor, or any MCP-compatible client. Resend offers two ways to connect: a fully hosted remote server at mcp.resend.com (Streamable HTTP, no local install, OAuth login on first connect) that works well for Claude web/desktop and Cursor, or the same open-source code run locally via `npx resend-mcp` (published to npm as `resend-mcp`) using stdio or HTTP transport for CI, headless agents, or self-hosted setups. Authentication is either OAuth (hosted mode, browser-based) or a Resend API key passed as a Bearer token — handy for servers where a browser login isn't possible. Setup is documented for Claude Code, Claude Desktop/web, Cursor, Windsurf, Codex, and GitHub Copilot in VS Code. Typical use: ask Claude to "send a welcome email to this new signup using our verified domain" or "list contacts added to the newsletter audience this week," and the MCP server routes the request through your existing Resend account — no custom SMTP or REST integration code required. With 546+ GitHub stars, it's one of the most widely adopted first-party MCP servers in the email/transactional-messaging category.
The WhatsApp MCP server connects Claude and other MCP clients directly to your personal WhatsApp account so an AI assistant can search, read, and send messages, contacts, and media through natural language. Unlike hosted bots that require the paid WhatsApp Business API, this community server (lharries/whatsapp-mcp, the most-adopted WhatsApp MCP server on GitHub) links to your regular account via the WhatsApp Web multidevice API using the Go whatsmeow library — you authenticate once by scanning a QR code, then re-authenticate roughly every 20 days. It runs as two components: a Go bridge that maintains the WhatsApp connection and stores your full message history in a local SQLite database, and a Python MCP server that exposes tools to the agent. Messages stay on your machine and are only sent to the LLM when a tool explicitly reads them, so you control what the model sees. Available tools cover searching contacts and chats, reading individual and group conversations (including images, video, documents, and audio), sending text messages to people or groups, and sending media — with optional FFmpeg-based conversion to play audio as native WhatsApp voice notes. Note the "lethal trifecta" caution in the README: because it combines private data, tool access, and external content, prompt injection could risk data exfiltration.
