A local/remote MCP server for generating infrastructure and architecture diagrams as code using the Python [diagrams](https://diagrams.mingrammer.com/) library ## Features **5 Diagram Tools** for infrastructure, architecture, and flowcharts: - **Infrastructure Diagrams** - 15+ providers (AWS, Azure, GCP, K8s, On-Prem, SaaS) - **500+ Node Types** - Compute, database, network, storage, security - **Custom Icons** - Web URLs (HTTPS) and local files - **Flowcharts** - 24 shapes for process diagrams - **Validation** - Dry-run before generation **Advanced Capabilities:** - Multiple output formats (PNG, PDF, JPG, DOT) - Cluster grouping with unlimited nesting - Edge styling (colours, labels, line styles) - Graphviz attribute customisation ## Installation **System Requirements:** - Graphviz must be installed: - macOS: `brew install graphviz` - Ubuntu/Debian: `sudo apt-get install graphviz` - Windows: Download from https://graphviz.org/download/ ### IDEs [](vscode:mcp/install?%7B%22name%22%3A%22diagrams%22%2C%22type%22%3A%22stdio%22%2C%22command%22%3A%22uvx%22%2C%22args%22%3A%5B%22diagrams-mcp%22%5D%7D) [](https://cursor.com/en-US/install-mcp?name=diagrams&config=eyJjb21tYW5kIjoidXZ4IGRpYWdyYW1zLW1jcCJ9) ### Claude Desktop Add to your `claude_desktop_config.json`: **For published package:** ```json { "mcpServers": { "diagrams": { "command": "uvx", "args": ["diagrams-mcp"] } } } ``` **For local development:** ```json { "mcpServers": { "diagrams:local": { "command": "uv", "args": [ "--directory", "/ABSOLUTE/PATH/TO/diagrams-mcp", "run", "diagrams-mcp" ] } } } ``` ### Claude Code **Quick setup (CLI):** Published package: ```bash claude mcp add --transport stdio math -- uvx diagrams-mcp ``` **Team setup (project-level):** Add `.mcp.json` to your project root: ```json { "mcpServers": { "diagrams": { "command": "uvx", "args": ["diagrams-mcp"] } } } ``` **Verify installation:** ```bash claude mcp list ``` Or check in IDE: View → MCP Servers, or use `/mcp` command. ## Try It Once installed, try these prompts: - "Create an AWS 3-tier web application diagram with Route53, ELB, EC2 instances, and RDS" - "Generate a Kubernetes microservices architecture with ingress, services, and pods" - "Build a flowchart for a CI/CD pipeline with decision points" - "Create a diagram using a custom icon from my company logo URL" - "Show me all available AWS compute nodes" Map to tools: `create_diagram`, `create_diagram_with_custom_icons`, `create_flowchart`, `list_available_nodes`, `validate_diagram_spec` ## Tool Reference All tool parameters and descriptions are available in your IDE's autocomplete. ### Diagram Generation (3 tools) | Tool | Description | | ---------------------------------- | ------------------------------------------------------------ | | `create_diagram` | Full infrastructure/architecture diagrams with all providers | | `create_diagram_with_custom_icons` | Diagrams with custom node icons from URLs or local files | | `create_flowchart` | Simplified flowchart creation with 24 process shapes | ### Discovery & Validation (2 tools) | Tool | Description | | ----------------------- | ------------------------------------------------------------- | | `list_available_nodes` | Search 500+ available nodes by provider, category, or keyword | | `validate_diagram_spec` | Dry-run validation before generation | ## Custom Icons ### Web URL Icons - HTTPS-only (HTTP rejected) - 5MB file size limit - 5-second download timeout - Image format validation (PNG, JPG) - Automatic caching (~/.diagrams_mcp/icon_cache) ### Local File Icons - Path validation (file must exist) - Format validation - Sandboxed execution
