"Mermaid" matching MCP servers:

Enables AI to create, edit, and manage Mermaid diagrams via MCP, with real-time preview in a browser-based editor.

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

MCP server for creating and editing diagrams using draw.io. Allows generating diagrams from Mermaid or XML, searching shapes, and opening them in draw.io for export.

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.

Connect AI assistants and scripts to LetDraw to read and author diagrams via MCP or REST, including creating diagrams from code, exporting to Mermaid/D2, and sharing read-only links.

Enables LLMs to create and open diagrams in the draw.io editor, supporting inline chat previews via MCP Apps, direct editor opening with XML/CSV/Mermaid format support, and diagram export to PNG/SVG/PDF or browser URLs through multiple integration approaches.

Converts Mermaid diagrams into Excalidraw diagrams, serves them locally, and opens the result in your browser.

Enables automatic generation of UML class diagrams and entity-relationship diagrams from natural language descriptions or structured JSON data. It integrates with MCP agents to create visual representations of code structures and system designs without manual Mermaid coding.

The diagram-quality layer for AI agents — an opinionated Excalidraw methodology (isomorphism test, evidence artifacts, multi-zoom, container discipline) plus a render-view-fix loop. Accepts skeleton and Mermaid input, 5 publishable themes, dual Node/Python renderer. Proven on a 77-diagram published book.
