Description

This server exposes multiple MCP tools to convert Markdown into markmap mindmaps, render Mermaid relationship graphs, and produce AI-analyzed knowledge graphs (Mermaid) rendered as images. It can run local CLI tools (markmap-cli and mermaid-cli) and call OpenAI-compatible endpoints to analyze text and generate graph code. Outputs can be returned directly (HTML/SVG) or saved to disk, with configurable default save directory and optional npx-based quick start. It is designed to integrate with MCP clients like Claude Desktop, Cherry Studio, DeepChat and HyperChat.
