MoldSim MCP Server
Wraps injection molding simulation expertise into six MCP tools: material property lookup for 21 thermoplastics with Cross-WLF viscosity and Tait PVT data, process parameter validation against processing windows, natural language to simulation spec generation, material comparison tables, DFM checklist generation with 15+ rule checks, and free-text Q&A against a knowledge base covering defects, meshing strategies, and process optimization. Built on Qdrant vector search with embedded HuggingFace transformers. Software-agnostic knowledge that applies to Moldflow, Moldex3D, Cadmould, and similar packages. Reach for this when you need Claude to troubleshoot warpage, recommend mesh types, validate melt temperatures, or generate structured simulation inputs without opening documentation.

MoldSim MCP Server
Give your AI assistant injection molding expertise.
An MCP (Model Context Protocol) server that gives AI assistants expert knowledge about injection molding simulation. Material properties, process validation, troubleshooting, and simulation specification generation — all available as tools.
Website: moldsim.com
Why
Setting up injection molding simulations (Moldflow, Moldex3D, Cadmould) requires deep knowledge: Cross-WLF viscosity models, Tait PVT data, processing windows, mesh strategies, DFM rules. This MCP server makes that knowledge available to any AI assistant that supports MCP.
Quick Start
Claude Code (recommended)
claude mcp add moldsim -- npx -y moldsim-mcp
That's it. Ask Claude about injection molding — it will automatically use MoldSim tools.
