veelenga/claude-mermaid
MCP Server to previewing mermaid diagrams with live reload
Implements an MCP server that streams Mermaid diagram renders to a local browser preview on port 3737, enabling real-time updates as Claude modifies diagram code. Supports multiple concurrent previews via `preview_id` parameters, persistent working files in `~/.config/claude-mermaid/live`, and export to SVG/PNG/PDF with customizable themes, dimensions, and styling. Integrates with Claude Code, Cursor, Cline, Windsurf, and other MCP-compatible clients through standard stdio transport configuration.
Available on npm.
