Eusend is a Model Context Protocol (MCP) server: Send transactional email and manage domains, audiences, and broadcasts from any MCP client. In practice that means any MCP-compatible AI assistant can call Eusend's tools directly — the model decides when to use them in a conversation or agent run.
You can run Eusend two ways: connect to the hosted endpoint at https://mcp.eusend.dev/mcp with no local install, or run it on your own machine via the npm package @eusend_dev/mcp. Configuration happens through environment variables — you'll need EUSEND_API_KEY. The current release is v0.4.0.
Eusend is listed under Communication on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
