#diagram

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.

Generate 25+ diagram types (flowchart, sequence, ER, mindmap, architecture, class, state, timeline, pie/bar/line chart, radar, kanban, wireframe, org chart, and more) as Excalidraw files with natural language. Features CJK support, 30+ tech brand colors, Sugiyama auto-layout, and one-line install via uvx.

The FlowZap MCP Server bridges AI coding assistants and FlowZap's diagramming engine, letting LLMs generate real, shareable Workflow, Sequence and Architecture diagrams in seconds. Pretty ones. - Installs in one command — npx -y flowzap-mcp — with no authentication required. - Works with Claude Desktop, Cursor, Windsurf, Zed, Warp, Cline, Roo Code, Continue.dev, OpenAI Codex, and more. - Core tools let AI agents validate FlowZap Code syntax, fetch syntax docs, and create shareable playground URLs. - Use it with its SKILL . md file for cleaner results: npx skills add flowzap-xyz/flowzap-mcp --skill flowzap-diagrams

It installs in one command — npx -y flowzap-mcp — with no authentication required. It works with Claude Desktop, Cursor, Windsurf, Zed, Warp, Cline, Roo Code, Continue.dev, OpenAI Codex, and more. The core tools let AI agents validate FlowZap Code syntax, fetch syntax docs, and create shareable but temporary playground URLs (one-hour TTL). Diagrams are exported as structured JSON graphs (lanes, nodes, edges) so AI agents can reason over them. It is listed on the official MCP registry (registry.modelcontextprotocol.io), npm, GitHub, among others. Use it with its SKILL . md file for cleaner results: npx skills add flowzap-xyz/flowzap-mcp --skill flowzap-diagrams Security: No Authentication Required - Public endpoints only; No User Data Stored. Playground sessions are ephemeral (60-minute TTL, non-guessable cryptographic tokens); No Tracking. No cookies or persistent identifiers Logs to stderr only - Security events never exposed to MCP clients.

An MCP server that generates live Mermaid diagrams from any AI assistant. Claude, Cursor, and more. https://iishyfishyy.github.io/mermaid-live-mcp/

Code-driven SVG diagram library for TypeScript/Node.js. Generate publication-quality architecture diagrams, flowcharts, and neural network diagrams with just a few lines of code. Features 10 shapes, 11 arrow heads, smart auto-routing with obstacle avoidance, and multi-format export (SVG/PNG/JPG/WebP/PDF). AI agents can generate diagrams through natural language via MCP integration.

sholarPlot MCP - AI-powered scientific figure generator for researchers. Create publication-ready charts, neural network diagrams, flowcharts & mechanism illustrations that meet Nature/Science/IEEE journal standards in seconds

An MCP server that enables interactive, browser-based user interfaces. It allows any MCP-aware AI chat client to generate charts, diagrams, visualizations, forms, calendars, and more — powered by context data, outputs from other tools, or synthesized by an LLM. The resulting UIs are fully interactive, editable, and customizable, making it easy to build dynamic workflows and visual experiences directly within the chat environment. Features: Chart Creation, Diagram Creation, Data Visualization, Form Generation, Calendar Creation, Date/Time Picker

A Model Context Protocol (MCP) server that provides PlantUML diagram generation capabilities.

A Model Context Protocol (MCP) server that provides PlantUML diagram generation capabilities for Claude Desktop and Claude Code.

A comprehensive MCP server that bridges the gap between LLMs and diagram creation through three powerful, independent tools: intelligent format selection, format-specific instruction generation, and professional diagram rendering (using kroki server). Each tool can be used standalone or combined in sequence for complete diagram workflows - from choosing the right format to generating the final image. Supported Formats: Mermaid, PlantUML, C4 Model, D2, GraphViz, BPMN, Structurizr, Excalidraw, Vega-Lite

Python MCP Server abstracting the official mermaid-cli for ease of use

MCP Server for the Sargoth Mermaid Editor API

MCP server creating Excalidraw diagrams via Claude Desktop, Cursor, or other hosts with a live web app preview.

Kroki-MCP is a Go-based Model Context Protocol tool that converts textual diagram definitions (PlantUML, Mermaid, and more) into images via a Kroki backend. Designed for simplicity and flexibility, it supports both local and remote Kroki servers, offers configurable settings, and outputs multiple formats – making it ideal for developers building AI

LikeC4 MCP Server provides knowledge of your LikeC4 model to LLMs. This enables you to query your model in natural language: - “Lookup LikeC4 model and list all incoming relationships of the backend api” - “What elements from the inside of the ‘Backend’ have relations with the legacy database” - “List all elements tagged ‘legacy’ from team1 project” - “What technologies are used for ui (consider all elements with browser shape)“

An MCP server providing tools for validating and rendering Mermaid diagrams.

UML-MCP Server is a UML diagram generation tool based on MCP (Model Context Protocol), which can help users generate various types of UML diagrams through natural language description or directly writing PlantUML and Mermaid and Kroki
