概要

What is Diagram Bridge Mcp?

Diagram Bridge Mcp is an MCP server that bridges LLMs and diagram creation through three independent tools: intelligent format selection (help_choose_diagram), format-specific instruction generation (get_diagram_instructions), and professional diagram rendering via a local Kroki service. It supports formats including Mermaid, PlantUML, C4 Model, D2, GraphViz, BPMN, Structurizr, Excalidraw, and Vega-Lite. Designed for developers using MCP clients (e.g., Cursor) who need LLMs to produce diagrams without manual format or rendering decisions.

How to use Diagram Bridge Mcp?

Install Node.js 18+, clone the repo, run npm install && npm run build, then start services with docker-compose up --build. Configure your MCP client to point to the built dist/index.js file. The server automatically provides three tools (help_choose_diagram, get_diagram_instructions, render_diagram) that can be used standalone or in sequence.
