LAD Render Cloud — SimaticML → ladder diagram over MCP

LAD Render Cloud renders a TIA Portal SimaticML block (FC / FB / OB) into a PNG ladder diagram — real ladder layout (contacts, coils, timers/counters, branch merges, jumpers, network titles, interface declaration table), not syntax highlighting and not a code screenshot.

Use it so an AI agent's generated ladder logic can actually be *looked at*, on a machine that has no TIA Portal installed.

This repository is documentation and client configuration only. The service runs at

tia.hubwiz.com; its implementation is not open source.

Endpoint: https://tia.hubwiz.com/render/mcp
Transport: Streamable HTTP (stateless, POST JSON-RPC)
Auth: Authorization: Bearer render_live_… (the X-API-Key header is also accepted)
Dashboard / API keys: https://tia.hubwiz.com/render
Registry entry: io.github.tia-forge/lad-render-cloud (official MCP Registry)

What it does

Tool	Purpose	Billing
`render_version`	Free: renderer version, supported languages / block types, size and input limits	free
`render_simaticml`	Take one SimaticML block, return its PNG ladder diagram	1 credit

initialize / tools/list / render_version are free; every other tools/call costs 1 credit, and one call submits exactly one block.

Inputs and limits

Accepted: FC / FB / OB blocks in LAD or SCL, including blocks where networks mix both.
Rejected with an explicit error: GlobalDB / InstanceDB / UDT / tag tables (no ladder diagram to draw) → UNSUPPORTED_DOCUMENT; FBD / GRAPH / STL → UNSUPPORTED_LANGUAGE.
Options: network renders a single 0-based network; scale (1–3) enlarges the image.
Limits: input XML 4 MiB, MCP request body 8 MiB, image 32,000,000 pixels with no side over 20,000 px, PNG 12 MiB, rate limit 120 requests/minute. Too tall, or scale too large → render one network instead of the whole block.

How to get SimaticML

In TIA Portal: right-click the block → Export → XML. The saved … text is the SimaticML this service expects. No TIA Portal at hand? Render one of the published example XMLs first.

Quick start

Claude Code

claude mcp add --transport http lad-render https://tia.hubwiz.com/render/mcp \

--header "Authorization: Bearer render_live_YOUR_KEY" claude mcp list

Cursor / VS Code / any JSON-configured client

"mcpServers": { "lad-render": { "url": "https://tia.hubwiz.com/render/mcp", "headers": { "Authorization": "Bearer render_live_YOUR_KEY" } } } }

First calls

// free — what does this renderer support right now?

{ "name": "render_version", "arguments": {} }

// one block → PNG (costs 1 credit) { "name": "render_simaticml", "arguments": { "xml": " … " } }

// a single network, 2× larger { "name": "render_simaticml", "arguments": { "xml": " … ", "network": 0, "scale": 2 } }

Pricing

Pack	Price	Per render
Free trial (new API key)	100 renders	—
1,000 renders	¥9.90	≈ ¥0.0099
5,000 renders	¥29.90	≈ ¥0.0060
15,000 renders	¥69.90	≈ ¥0.0047

No subscription, no monthly fee; balance is applied immediately, and render_version / tools/list never consume credits.

Scope

Renders text only: it does not connect to TIA Portal, does not read or write a project, and never downloads to a device. For on-premise project work use the TiaLink MCP gateway (https://github.com/tia-forge/tialink) instead.
Output is for reading and review — it does not replace compiling the block in TIA Portal or commissioning on site.
