unmarkdown/mcp-server

Connects Claude to the Unmarkdown API for converting markdown into styled HTML across eight destinations including Google Docs, Word, Slack, and email.

Supports 62 visual templates ranging from free options like Swiss and GitHub to Pro business themes. Useful when you need AI-generated content formatted for specific platforms without manual styling, or when building a document library with public publishing. Includes usage tracking to monitor your monthly quota. Requires an Unmarkdown API key and works via stdio or streamable HTTP transport.
