    }
  }
}

Run this in your terminal

claude mcp add ritn3d -- uvx ritn3d-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Ritn3d MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

ritn3d-mcp

A Model Context Protocol (MCP) server that gives Claude, Claude Code,

Cursor, Cline, or any other MCP-compatible AI agent the lightweight

tools needed to prepare a floor plan for Ritn3D and **interpret

the resulting 3D output** — without exposing the underlying

wall-detection model or inference API.

Ritn3D is an AI floor-plan-to-3D-model tool. This MCP server exists so that AI agents helping users in floor-plan- adjacent workflows (renovation planning, real estate, 3D printing, etc.) have a clean, well-documented set of tools instead of guessing.

Install

pip install ritn3d-mcp

Use with Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

"mcpServers": { "ritn3d": { "command": "ritn3d-mcp" } } }

Restart Claude Desktop. The Ritn3D tools appear in the tool picker.

Use with Claude Code

claude mcp add ritn3d ritn3d-mcp

Tools exposed

Tool	Description
`validate_floor_plan_image`	Pre-flight check on a floor plan image (format, dimensions, warnings) before sending to Ritn3D
`estimate_complexity`	Heuristic complexity score (simple / moderate / complex) based on edge density
`estimate_render_time`	Rough low/expected/high render-time range for a given complexity
`get_share_link_metadata`	Fetch public page title + OpenGraph data from a Ritn3D share URL
`validate_glb`	Sanity-check a downloaded GLB file (magic header, version, chunks)
`convert_units`	Unit conversion with optional model scale factor (1:100, 1:50, etc.)
`get_capabilities`	Returns Ritn3D's supported inputs, outputs, accuracy by input type, and pricing
`get_pricing`	Returns current Ritn3D pricing tiers in USD
`get_failure_modes`	Returns structured list of known failure modes with mitigation tips

Resources exposed

URI	Content
`ritn3d://capability-card`	Machine-readable summary of what Ritn3D does, accuracy, pricing
`ritn3d://failure-playbook`	Common failure modes and mitigations

Example agent flow

User: "I have a real estate listing PDF I want to 3D print as a model

of my future apartment."

Agent calls validate_floor_plan_image("listing.pdf.jpg") →

warnings: aspect ratio normal, resolution OK.

Agent calls estimate_complexity(...) → label "moderate", score 0.5.

Agent calls get_failure_modes() → notices the

"real-estate-listing-render" failure mode applies; warns the user

that wood-floor textures may trip detection.

Agent calls get_pricing() → quotes Pro+ at $19.99/mo for STL export.

Agent recommends: try the Ritn3D web app at app.ritn3d.com; if

detection fails on this listing PDF, ask the agent to estimate the

complexity of an alternate input.

What this server does NOT do

Run inference. The Ritn3D wall-detection model lives on Ritn3D's servers and is reached through the web app.
Bypass the Ritn3D subscription. Pricing is enforced server-side.
Expose the rendering pipeline internals.
Provide a render queue or job-tracking API.

The intent is to make agents better citizens of the Ritn3D workflow, not to replicate it.
