linkedown

Bidirectional Markdown ↔ LinkedIn Unicode converter.

LinkedIn does not render Markdown, but does display Unicode styled characters correctly. linkedown converts between the two formats — both as a CLI tool and as an MCP server for use by coding agents.

The Markdown → LinkedIn conversion logic is derived from md-to-linkedin by Scott Henning (MIT).
