Converts Markdown to Feishu (Lark) document format, handling images and Mermaid flowcharts along the way. Built as part of a monorepo with a core conversion library and this MCP wrapper on top. You'd reach for this when you need Claude to generate content that ends up in Feishu docs without manual reformatting. The core library transforms Markdown into Feishu's document structure, and the MCP server exposes that conversion through the Model Context Protocol. Useful if your team lives in Feishu and you want AI generated documentation to land there cleanly. The package is on npm and uses stdio transport for communication.
