The Mermaid Validator is a Model Context Protocol (MCP) server designed to validate and render Mermaid diagrams. It allows Large Language Models (LLMs) to accurately verify and visualize Mermaid syntax, ensuring that diagrams are correctly formatted and visually represented. By integrating with the Mermaid CLI, this server provides a robust solution for validating diagram syntax and generating SVG outputs, enhancing the reliability of diagram generation and interpretation within AI-driven applications.
