emailmd is a Model Context Protocol (MCP) server: Render markdown into email-safe HTML, lint drafts for deliverability problems, and preview emails. Because it speaks the Model Context Protocol, AI assistants can use emailmd as a set of callable tools instead of you copy-pasting between apps.
You can run emailmd two ways: connect to the hosted endpoint at https://www.emailmd.dev/api/mcp with no local install, or run it on your own machine via the npm package emailmd. The current release is v0.11.0, published under the MIT license, with source at anypost/emailmd on GitHub, where it has earned 1.3k stars.
On mcp.site, emailmd sits in the Communication category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
