Markmap MCP Server

What is Markmap MCP Server?

Markmap MCP Server is an MCP‑based tool that converts Markdown text into interactive mind maps with one click. Built on the open‑source markmap library, it supports zooming, expanding/collapsing nodes, and exporting mind maps as PNG, JPG, or SVG images.

How to use Markmap MCP Server?

Install the package globally via npm install @jinzcdev/markmap-mcp-server -g or run directly with npx -y @jinzcdev/markmap-mcp-server. Configure your MCP client with a stdio server entry using that command. The tool provides one command – markdown-to-mindmap – which requires a markdown string and accepts an optional open boolean to automatically preview the mind map in a browser. Output directory can be set with the --output argument or the MARKMAP_DIR environment variable.
