ritn3d-mcp

<!-- mcp-name: io.github.printplan3d/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.
