"Mermaid" matching MCP servers:

A basic MCP server example with a hello tool, info resource, and assistant prompt, built with TypeScript and Node.js using the official MCP SDK.

An MCP server that generates diagrams from Mermaid code in multiple formats (PNG, PDF, SVG).

Enables AI assistants to analyze code repositories and generate self-contained interactive HTML5/SVG architecture diagrams from project structure or existing Mermaid diagrams, fully air-gapped with no external dependencies.

Enables AI hosts to generate and open Mermaid diagram links in Markdown files, providing tools for syncing, listing, and injecting diagrams via the Mermaid.ai editor.

13 AI-powered UML diagram tools for coding agents. Generates class, sequence, state, ER, threat model, deployment and architecture diagrams in Mermaid syntax. Works in Claude Code, Cursor and Windsurf.

Generates Excalidraw architecture diagrams with support for 60+ components including GCP, Kafka, and AI/Agentic shapes. Provides MCP tools for creating, modifying, and converting diagrams from structured input or Mermaid syntax.

Enables AI hosts to generate editable online diagrams (flowcharts, mindmaps, UML, and more) from natural language or Mermaid, using a ProcessOn account via the Model Context Protocol.

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.

Provides read-only structural analysis of codebases, surfacing architecture smells with traffic-light ratings and rendering dependency relationships as Mermaid flowcharts.

Enables creating, reading, and managing HedgeDoc 1.x notes and Mermaid diagrams from AI agents via the MCP protocol.

MCP server + Claude Code plugin for ComfyUI: execute workflows, generate images, visualize pipelines as Mermaid diagrams, compose/validate workflows, manage and download models, control VRAM, and explore custom nodes. 36 tools, cross-platform, installs via npx -y comfyui-mcp.

Analyzes code repositories and generates comprehensive documentation published to Google Docs with Mermaid diagrams.
