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 CLI for Headless Automation

Use KosmoKrator as a non-interactive integration runtime for local automations and wrappers.

Use headless automation when another tool needs a stable local command surface. The PlantUML CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# PlantUML CLI for Headless Automation
kosmokrator integrations:configure plantuml --enable --read allow --write ask --json
kosmo integrations:call plantuml.render_plantuml '{"syntax":"example_syntax","title":"example_title"}' --json

Discovery Before Execution

Agents and scripts can inspect PlantUML docs and schemas before choosing a function.

kosmo integrations:docs plantuml --json
kosmo integrations:docs plantuml.render_plantuml --json
kosmo integrations:schema plantuml.render_plantuml --json
kosmo integrations:search "PlantUML" --json
kosmo integrations:list --json

Useful PlantUML CLI Functions

Function	Type	Parameters	Description
`plantuml.render_plantuml`	Write	syntax, title	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

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
