"UML diagram generation tools and software like Mermaid or Visio" matching MCP servers:

Enables visual drag-and-drop editing of Mermaid diagrams through Claude, allowing iterative refinement of software architecture designs.

Renders Mermaid diagram markup to PNG images using Puppeteer/Chromium. Enables AI-generated diagrams to be previewed inline and saved to disk.

A flow diagram generator and MCP server that helps LLMs create better visuals using tools like create_diagram, add_node, add_edge, and visualize_diagram. It integrates with Cursor and outputs SVG, HTML, Mermaid, and more.

Renders diagram-as-code to PNG files on your disk, and also provides text-art previews and syntax validation, all locally without a browser or network.

MCP Server to previewing mermaid diagrams. https://github.com/veelenga/claude-mermaid/

Renders Mermaid diagrams and Plotly charts to SVG, PNG, or PDF formats via the Model Context Protocol.

❤️ Generate mermaid diagram and chart with AI MCP dynamically.

Enables agents to search official Mermaid diagram syntax documentation and validate Mermaid diagram code before presenting it to users, ensuring syntactically correct flowcharts, sequence diagrams, class diagrams, and other Mermaid visualizations.

Provides software design guidance via MCP, including SOLID principles, design patterns, pattern scaffolding, and heuristic code-smell detection to help review and refactor code.

MCP server for AI Diagram Maker — generate software engineering diagrams from natural language, code, ASCII diagram, images, or Mermaid. Inline diagram rendering using MCP apps UI and diagram URL in responses. Works with Cursor, Claude Desktop, Claude Code, and any MCP-compatible AI.

MCP server for generating diagrams, charts, and visualizations using Gemini image generation on Vertex AI. Supports auto-detection of diagram types, multiple style modes, and iterative refinement.

A Model Context Protocol (MCP) server for validating Mermaid diagram syntax and providing comprehensive grammar checking capabilities

Generates SVG diagram files from Mermaid syntax with support for multiple themes and customizable backgrounds, using Puppeteer for reliable rendering.

A tool for validating Mermaid diagram syntax through CLI and MCP interfaces, providing real-time error checking and line-specific feedback. It enables AI assistants to self-validate and debug generated diagrams across all Mermaid types, ensuring valid visual documentation.

Enables AI assistants to generate and render Mermaid diagrams (flowcharts, sequence diagrams, etc.) as PNG/SVG images with local file saving and HTTP access URLs. Supports batch processing and intelligent caching for efficient diagram creation.

Provides live wait times and office details for all 60 Oregon DMV field offices by scraping the ODOT website, with no authentication required.

Enables Claude to function as a full-stack software engineer with comprehensive development capabilities including project creation, database management, frontend/backend development, testing, deployment, and DevOps operations across multiple frameworks and technologies.

Enables AI agents and users to render Mermaid diagram code blocks into embedded SVGs within Obsidian notes locally, while preserving reversible synchronization with sidecar .mmd files.

Bridges LLMs and diagram creation by providing intelligent format selection, format-specific instruction generation, and professional diagram rendering across 9+ formats including Mermaid, PlantUML, C4 Model, and GraphViz.

MCP server that generates Mermaid diagrams with live browser preview, supports real-time rendering and SVG/PNG export.
