Can I use PlantUML as a CLI?

Yes. KosmoKrator exposes a PlantUML CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose PlantUML through MCP?

Yes. The KosmoKrator MCP gateway can expose selected PlantUML tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are PlantUML credentials stored?

PlantUML credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for PlantUML MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

PlantUML for agents

No credentials required; available in web and CLI hosts when runtime dependencies are installed.

Use this integration from Lua code mode, the headless integrations CLI, or the KosmoKrator MCP gateway. The same package metadata powers all three surfaces.

Function Catalog

Function	Type	Parameters	Description
`plantuml.render_plantuml`	Write `write`	2	Render a PlantUML diagram to a PNG image. Pass valid PlantUML syntax and get back a markdown image embed. Supported diagram types: class, sequence, activity, component, state, use case, object, deployment, timing, network (nwdiag), wireframe (salt), Gantt, mindmap, WBS, JSON, YAML, ERD. Example syntax: ``` @startuml Alice -> Bob: Authentication Request Bob --> Alice: Authentication Response Alice -> Bob: Another request Bob --> Alice: Another response @enduml ``` Tips: - Always wrap syntax in @startuml / @enduml - Use `->` for solid arrows, `-->` for dashed arrows - Use `class ClassName { }` blocks for class diagrams - Use `(*) -->` for activity diagram start - Use `[Component]` for component diagrams - Use `state "Name" as s1` for state diagrams
