What is the Maid MCP Server?

Fast, accurate Mermaid diagram validator (CLI) with clear diagnostics.

What it actually does

Fast, accurate Mermaid diagram validator with clear, actionable diagnostics. Built for the AI age where Mermaid has become essential—but validation shouldn't require a browser.

  • Built for AI — Designed for AI agents and LLMs that generate Mermaid diagrams
  • Render Guarantee — When Maid says it's valid, your diagram will render
  • Lightning Fast — Validates in milliseconds without launching a browser
  • Human-Friendly — Clear error messages with line numbers, carets, and actionable hints
  • Lightweight — ~5MB vs. mermaid-cli's 1.7GB (Puppeteer + Chrome)
  • Auto-Fix — Automatically corrects common AI-generated mistakes
