Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “render_diagram”: Render PlantUML source text to a diagram image. Returns a PNG image block (format "png") or the SVG markup as text (format "svg", default),.”
“Use “validate_diagram”: Check PlantUML source without rendering. Returns {ok:true, diagram_type} or {ok:false, error:{code, message, line, column, source_line, hint.”
“Use “encode_source”: Encode PlantUML source into a URL token and ready-to-use share/render URLs (svg + png). The result carries url_ok: GET URLs only work while.”
“Use “decode_token”: Recover the PlantUML source from a token or from any PlantUML render URL (the token is extracted automatically). Tokens use PlantUML's own 6.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how uml.singsk.com PlantUML holds up.
Operated by uml.singsk.com PlantUML (singsk.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If uml.singsk.com PlantUML adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose uml.singsk.com PlantUML in the gate directory. No sign-in needed.
uml.singsk.com PlantUML's tools are live in every AI client you've connected — with rules and logging built in.

https://uml.singsk.com/mcpYes — uml.singsk.com PlantUML operates its own remote MCP server at uml.singsk.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

No. uml.singsk.com PlantUML runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Yes — you can get started with gate for free and connect uml.singsk.com PlantUML in minutes. No credit card required.
