What is Diagrams?

Diagrams is an MCP server for generating cloud architecture diagrams, flowcharts, sequence diagrams, and more, powered by three rendering engines: mingrammer/diagrams, Mermaid, and PlantUML.

How to use Diagrams?

Connect to the public hosted server by adding its URL to your MCP client configuration (e.g., Claude Desktop, Claude Code, Cursor, Windsurf, VS Code). For local usage, install via uvx or pip, ensure required dependencies (mainly Graphviz), and configure your client.

Key features of Diagrams

Three rendering engines: mingrammer/diagrams, Mermaid, PlantUML
Hosted server available with no installation required
Tools for discovering provider nodes, services, and equivalents
Renders cloud architecture, flowcharts, sequence diagrams, and more
Supports cross-provider equivalence lookup
Provides reference documentation via MCP resource URIs

Use cases of Diagrams

Generate AWS cloud architecture diagrams programmatically
Create CI/CD pipeline flowcharts with Mermaid
Render sequence diagrams for authentication flows
Find equivalent services across cloud providers (e.g., AWS to GCP)
Quickly produce UML diagrams for documentation or presentations

常见问题

Do I need to install anything locally to use Diagrams?

No. The hosted server has all dependencies pre-installed. Local installation requires Graphviz, and optionally Mermaid CLI and PlantUML.

What rendering engines does Diagrams support?

Three: mingrammer/diagrams for cloud architecture, Mermaid for flowcharts/sequence diagrams, and PlantUML for UML diagrams.

How do I connect to the hosted Diagrams server?

Add its URL (`https://diagrams-mcp-production.up.railway.app/mcp`) to your MCP client configuration as shown in the README.

Can I find equivalent services across cloud providers?

Yes, use the `find_equivalent` tool to discover equivalent nodes (e.g., AWS EC2 to GCP Compute Engine).

What diagram types can Diagrams generate?

Cloud architecture diagrams, flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, Gantt charts, component diagrams, activity diagrams, and more, depending on the engine.
