A Mermaid diagram rendering MCP server for Claude Code with live reload functionality, supporting multiple export formats (SVG, PNG, PDF) and themes.

Give your AI coding agent an architecture canvas to design and evolve diagrams.

AI-powered Mermaid diagram generation with 22+ diagram types including flowcharts, sequence diagrams, class diagrams, ER diagrams, architecture diagrams, state machines, and more. Features 50+ pre-built templates, advanced layout engines, SVG/PNG/PDF exports, and seamless integration with GitHub Copilot, Claude, and any MCP-compatible client. Install via NPM: npm install -g @narasimhaponnada/mermaid-mcp-server

FlowchartAI MCP connects AI assistants to editable flowcharts. Generate diagrams from text or an image, revise an existing diagram with natural-language instructions, list and read saved diagrams, inspect task and version history, and export editable draw.io XML or JSON. Saved diagrams open in the FlowchartAI web editor for further editing and PNG/SVG rendering. The hosted Streamable HTTP endpoint supports OAuth with PKCE and scoped API keys. Generation and edits use the existing account allowance or Credits, with per-task spending caps and account/key budgets. The public repository is MIT licensed; the hosted service requires a FlowchartAI account.
