Creates diagrams via the uml-mcp MCP server (generate_uml, generate_uml_image, validate_uml, list_diagram_types, generate_uml_batch) and returns shareable Kroki URLs or inline chat images. Use when the user wants diagrams, PlantUML/Mermaid/D2/UML, URLs, Kroki, goat/umlet, or diagram_type.
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
> **Maintainers:** Keep tool tables and `output_dir` wording aligned with the Smithery bundle **[uml-skill/SKILL.md](https://github.com/antoinebou12/uml-skill/blob/main/SKILL.md)** (`diagramming-uml`) and the Claude Code plugin skill **`plugins/uml-mcp/skills/uml-diagrams/SKILL.md`** when you edit any of them. **`.github/skills/uml-mcp-diagrams/SKILL.md`** (GitHub Copilot) must stay a byte-identical copy of this file. # uml-mcp diagram workflow ## Goal Turn the user’s intent into valid `diagram_type` + source `code`, call **generate_uml** (or **generate_uml_image** for chat-visible pictures), and surface the **`url`** (and **`playground`** when present). Prefer **URL-first** output (omit `output_dir` / use `null`) unless the user explicitly asks to save a file. When the user asks to **show the diagram in chat**, prefer **`generate_uml_image`** with `output_format: png`. ## Positive patterns (do) - **Confirm types first** when unsure: read **`uml://types`** / **`uml://formats`** or call **`list_diagram_types`** before **`generate_uml`**. Catalog includes ~37 Kroki-backed types (including **`goat`**, **`umlet`**). …

How to install
mdr add antoinebou12/uml-mcp/uml-mcp-diagrams@sha256:43a4455c34059c2fThe line at the top of this page pins the label git:20260925.e474cbe, 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.
