Writes valid actdiag diagram source for uml-mcp (diagram_type=actdiag). Activity and workflow diagrams (blockdiag family) Use when the user asks for actdiag 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
# actdiag diagram (uml-mcp)
**`diagram_type`:** `actdiag`
**Backend:** `actdiag`
**Output formats:** png, svg, pdf
Activity and workflow diagrams (blockdiag family)
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.
## Styling
- Same family as blockdiag; label lanes and edges clearly.
- No MCP `theme` param.
## Starter template
```actdiag
actdiag {
input -> process -> output
lane user {
input [label = "Input"];
output [label = "Output"];
}
lane system {
process [label = "Process"];
}
}
```
## Example
```actdiag
actdiag {
write -> convert -> image
lane user {
label = "User"
write [label = "Writing text"];
image [label = "Get diagram image"];
}
lane Kroki {
convert [label = "Convert text to image"];
}
}
```
## Render with uml-mcp
1. Set `diagram_type` to `actdiag` exactly.
2. Call **`validate_uml`** when the source is untrusted (prefer `strict: true` for Mermaid sequence).
3. Call **`generate_uml`**, **`generate_uml_image`** (chat PNG), or **`generate_uml_batch`**.

How to install
mdr add antoinebou12/uml-mcp/actdiag@sha256:25c2c18e7cb770f6The 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.
