Writes valid activity diagram source for uml-mcp (diagram_type=activity). Shows workflows or business processes Use when the user asks for activity or that notation; then call validate_uml / generate_uml / generate_uml_image.
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
# activity diagram (uml-mcp) **`diagram_type`:** `activity` **Backend:** `plantuml` **Output formats:** png, svg, pdf, txt, base64 Shows workflows or business processes Load the workflow skill [uml-mcp-diagrams](../uml-mcp-diagrams/SKILL.md) for URL-first replies, progressive discovery, and which MCP tool to call. This file is notation only; it does not add an MCP tool. ## Notation tips - Use `start`/`stop`, decisions (`if`/`endif`), `fork`/`join`, and swimlanes when multiple actors. - Label every branch exit. ## Themes Pass **`theme`** to `generate_uml` / `generate_uml_image` (PlantUML built-in name). The server injects `!theme <name>` after `@startuml` when the source has no `!theme` yet. Recommended: `cerulean`, `materia`, `sketchy`, `cyborg`, `plain`, `aws-orange`, `blueprint`, `sandstone`. Match the **page background** (also see MCP prompt **`diagram_theme`**): - light / white: `cerulean`, `materia`, `plain`, `sketchy`, `sandstone` - dark / black: `blueprint`, `cyborg`, `black-knight`, `carbon-gray`, `crt-green` - B&W / print: `plain`, `sketchy`, `sketchy-outline`, `mimeograph`, `lightgray` Or embed in source: ```plantuml @startuml !theme cerulean ' … diagram … …

How to install
mdr add antoinebou12/uml-mcp/activity@sha256:aacd6edbcd591b20The line at the top of this page pins the label git:20261023.634e385, 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.
