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 Coding Agents

Use the PlantUML CLI for coding agents with headless JSON commands, schema discovery, credentials, and permission controls.

PlantUML CLI for Coding Agents

Let coding agents discover schemas and execute integration functions through CLI commands or MCP.

Use this pattern when another coding agent needs exact commands and schema discovery. 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 Coding Agents
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.
