Draw auto-laid-out stack and cloud architecture diagrams with real logos (stack_diagram).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Stack diagrams Follow `skill://uml-mcp-diagrams/SKILL.md`. Icon tiles on engineered paper, nested vendor and region groups and labelled right-angled edges, laid out for you left to right, right to left, top down or bottom up. ## Types | Type | Use for | Example prompt | | --- | --- | --- | | `stack_diagram` | a stack or cloud diagram with icon tiles, nested vendor and region groups | Draw my stack: Next.js and Hono on Vercel, Neon Postgres, Clerk for auth, Stripe for payments, GitHub Actions deploys. Left to right. | ## Steps 1. Check the live catalog (`list_diagram_types` or `uml://types`); the bundled plugins are on by default, but a server may turn them off with `plugins.bundled: false`. 2. Read the type's example from `uml://examples` and keep its field names. 3. Call `validate_uml`; an error names the field and, for a bad reference, lists the known ids, so fix it and validate again. 4. Render with `generate_uml_image` for a chat image, or `generate_uml` with `output_format: "html"` for the interactive page in the MCP App viewer. Clients without MCP Apps still get the PNG and SVG. 5. Pass `theme` (`auto`, `dark`, `light`) rather than editing colours. ## Example …

How to install
mdr add antoinebou12/uml-mcp/uml-mcp-stack-diagram@sha256:16a7da925e7407f0The line at the top of this page pins the label git:20261105.4b281d9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
