Mermaider

概要

Mermaider is an MCP server designed to efficiently validate Mermaid diagram syntax. By utilizing a headless browser (Chrome or Firefox) and the mermaid-js/mermaid API, it provides low-latency syntax checking. Unlike other solutions that launch a new browser instance for each validation, Mermaider keeps the browser running, significantly improving speed and reliability when used with LLMs to generate diagrams.
