Injection molding simulation expertise — materials, process validation, and DFM checks
MoldSim MCP server exists for a simple reason — assistants are far more useful when they can act on MoldSim directly instead of describing what you should do. Injection molding simulation expertise — materials, process validation, and DFM checks.
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.
Installation goes through your MCP client rather than a global install: point it at moldsim-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Once MoldSim is connected, these are the calls the assistant has available:
query_simulation_knowledge — Free-text Q&A against the knowledge base. Ask about defects, DFM rules, mesh strategies, process optimizationget_material_properties — Material property lookup. Returns Cross-WLF viscosity, Tait PVT, thermal, processing window, and mechanical datavalidate_process_parameters — Checks your process parameters against the material's processing window. Flags errors, warnings, and provides suggestionsgenerate_simulation_spec — Natural language → structured simulation specification. Describe the part and get back analysis types, mesh recommendations, process conditions, andcompare_materials — Side-by-side comparison of 2-4 materials. Processing windows, thermal properties, mechanical data, and auto-generated key differencesgenerate_dfm_checklist — Design for Manufacturability checklist with pass/warn/fail ratings. Input part parameters and get 15+ DFM rule checksAmong the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MoldSim's toolset — query_simulation_knowledge, get_material_properties, validate_process_parameters and 3 more — is a fair guide to whether it matches your workflow. It is maintained by kobzevvv; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
