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

Analyzes C++ source code to automatically generate UML class diagrams in PlantUML format, extracting classes, inheritance relationships, and member visibility from directories or file contents.

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

MCP server for rendering Mermaid diagrams and generating source-code diagrams, with tools to render text/files and produce dependency/class diagrams.

Enables AI assistants to generate and validate 30+ UML and other diagram types (Mermaid, D2, Graphviz, BPMN, C4, and more) through the Model Context Protocol, returning rendered SVG, PNG, PDF, JPEG, or base64 output via Kroki, PlantUML, and Mermaid backends.

Enables MCP clients to generate and structurally validate 30+ diagram types—UML (class, sequence, activity, state, component, and more), Mermaid, D2, Graphviz, TikZ, ERD, BPMN, and C4—via Kroki, PlantUML, and Mermaid.ink, returning rendered SVG/PNG/PDF/JPEG as URLs, base64 payloads, or saved files through tools like generate_uml and generate_uml_batch.

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

Enables generating diagrams in Microsoft Visio on Windows with real stencil shapes, glued connectors and automatic layout, editing drawings already open in Visio, and reading drawings as context.

An MCP server that renders Mermaid diagram syntax to PNG, SVG, PDF, or draw.io format, enabling LLMs to convert diagram descriptions into actual images.

Drives Microsoft Visio desktop via COM automation to create, style, and layout diagrams such as flowcharts and cloud architecture, then exports PNGs for visual feedback and iteration.

Generates UML and other diagrams (30+ types) via the Model Context Protocol, supporting multiple output formats and deployment options.

Enables LLM agents to create circuit schematics and diagrams in Microsoft Visio through MCP tools for managing documents, pages, stencils, shapes, wires, and exports, with measured pin geometry for accurate component connections.

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.

Enables AI assistants to generate UML diagrams through natural language by rendering PlantUML code into PNG or SVG images. Supports sequence diagrams, class diagrams, use case diagrams, and other UML chart types with Base64-encoded output.

Provides MCP tools to read, validate, propose, and review architecture models and UML diagrams in local workspaces.

Enables desktop MCP clients to launch a local connector that renders Mermaid flowcharts from an AI assistant into a browser-based reader served on localhost. Users can explore a diagram step by step, inspect a step's incoming and outgoing connections, read relationships as text, and save the Mermaid source.

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/

Lets agents construct Mermaid diagrams from structured JSON IR and render them as PNG or SVG.

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 to create and edit Microsoft Visio diagrams programmatically via a standardized API.

Enables AI agents to query OpenRouter model information including prices, ELO rankings, context, and perform comparisons.

Enables AI agents to interact with a local Mermaid diagram editor via MCP, allowing them to get and set diagrams programmatically.

Provides MCP tools to validate Mermaid diagram syntax, render diagrams to SVG, and get documentation links.

A lightweight MCP server that provides real-time Mermaid diagram syntax validation with support for all diagram types.

Agent-driven animated diagram renderer that turns API/flow descriptions into animated MP4s or Instagram-style carousels, designed to be driven by an AI agent over MCP.

Enables AI agents to list, read, create, update, and delete Mermaid diagrams and collections via the Mermaid REST API over stdio or stateless Streamable HTTP.

A Windows MCP server for creating fully editable Microsoft Visio diagrams with compact SCI/IEEE styling, native arrowheads, obstacle-aware routing, and a pre-export geometry audit.

A local-first toolkit that rebuilds reference images as editable Microsoft Visio shapes via two MCP servers for image QA and Visio COM rendering.

Enables Claude to draw Mermaid diagrams as live, inline canvases in the reply instead of printing them as code blocks. The rendered diagram can be zoomed, panned, re-themed, expanded in height, and flipped to a highlighted, copyable source view.
