plantuml-server
plantuml-server provides a service for rendering PlantUML diagrams from diagram definitions, typically via HTTP endpoints (e.g., accepting PlantUML text and returning an image like SVG/PNG).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security posture cannot be determined from the provided information. PlantUML-based servers can be risky when rendering untrusted input if PlantUML directives allow external includes or file access; deploy with network/filesystem restrictions and input validation/sandboxing where possible.
⚡ Reliability
Best When
You want programmatic diagram rendering and can safely control/validate PlantUML inputs (and any include/resource mechanisms).
Avoid When
You cannot restrict PlantUML features (e.g., !include, !includeurl) or cannot deploy the server in a sandboxed environment when input is untrusted.
Use Cases
- • Generating diagrams from PlantUML source in an application or CI pipeline
- • Building internal documentation portals that render PlantUML on demand
- • Live preview of PlantUML diagrams in web apps/editors
Not For
- • Producing diagrams from untrusted or attacker-controlled input without isolation/sandboxing
- • High-security environments that cannot risk SSRF/filesystem access if the server supports PlantUML includes/resources
- • Complex workflows requiring OAuth/enterprise identity or managed multi-tenant isolation (based on lack of evidence here)
