Overview

AI-generated overview

A remote MCP server that checks whether rotational-molding molds fit together on a machine arm, using a deterministic geometric layout engine.

What you can do
Check mold layouts on a rotational-molding machine arm: rotation-envelope and dead-height checks, pairwise mold-to-mold clearance, offset-arm riser selection, and ring arrangements for three or more identical molds, all from a deterministic geometric engine rather than estimates. Send feedback to the maintainers: relay a question, bug report or suggestion, with an optional reply address.
When to use it
Useful when planning rotomolding production and you need to know which molds can be mounted together on an arm or spider and how they should be arranged, before committing to a setup.
Requirements
A remote streamable HTTP endpoint; no local runtime, package, account, API key or header is declared.
Before you install
The feedback tool sends your message, and any contact address you volunteer, to the server's maintainers. Layout results come from a geometric engine and should be verified against the actual machine before production.

Installation

In SourceWeft

  1. Open Zhihuo RotoSpider Layout in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/net.zhihuo.mcp%2Frotospider-layout/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

check_mold_layout

Check mold layout on a rotomolding machine arm

Check whether molds fit together on a rotational-molding machine arm. Every answer comes from the deterministic RotoSpider geometric layout engine: rotation-envelope and dead-height checks, pairwise mold-to-mold clearance, offset-arm riser selection, and ring arrangements for 3+ identical molds. It never returns a physically invalid layout. Args: molds: List of mold objects. Use one explicit unit convention: Box/frame mold: {"length_mm": L, "width_mm": W, "height_mm": H}. Cylinder/tank mold: {"diameter_mm": D, "height_mm": H}. Exact L, slope, triangle, frustum, or complex mold: measured length_mm+width_mm+height_mm plus the complete geometry_asset_id+geometry_asset_revision returned by the geometry WebAPI or another trusted publisher. Decimal-inch aliases are length_in, width_in, height_in, and diameter_in. Each value is converted once to canonical micrometres; do not give both aliases for the same value. Optional per mold: "name", "weight_kg", "quantity" (default 1; use 0 to retain the mold type without requesting a copy). machine: Public-sample straight-arm preset. Available models are listed in the tool description. Leave empty AND give no explicit geometry to scan all presets ("which machine can take these molds?"). arm_type: 'straight' (dual spiders) or 'offset' (single-spider offset/L arm). Empty = both. spider_diameter_mm: Custom machine - spider (mounting plate) diameter. Giving this plus envelope_diameter_mm switches to custom-machine mode instead of presets. envelope_diameter_mm: Custom machine - rotation envelope diameter (for offset arms: the vertical envelope diameter).
