Material properties, process validation, troubleshooting, and simulation specification generation — all available as tools.\n\n**Website:** [moldsim.com](https://moldsim.com)\n\n## Why\n\nSetting 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.\n\n## Quick Start\n\n### Claude Code (recommended)\n\n```bash\nclaude mcp add moldsim -- npx -y moldsim-mcp\n```\n\nThat's it. Ask Claude about injection molding — it will automatically use MoldSim tools.\n\n```bash\nclaude \"What causes warpage in glass-filled nylon parts?\"\nclaude \"Give me the Cross-WLF parameters for PC/ABS\"\nclaude \"Validate: ABS at 245C melt, 60C mold, 2.5mm wall\"\n```\n\n### Claude Desktop\n\nAdd to `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%/Claude/claude_desktop_config.json` (Windows):\n\n```json\n{\n  \"mcpServers\": {\n    \"moldsim\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"moldsim-mcp\"]\n    }\n  }\n}\n```\n\n### From source\n\n```bash\ngit clone https://github.com/kobzevvv/moldsim-mcp.git\ncd moldsim-mcp\nnpm install\nnpm run build\n```\n\nThen point your MCP client to `node dist/index.js`.\n\n## Tools\n\n### `query_simulation_knowledge`\nFree-text Q&A against the knowledge base. Ask about defects, DFM rules, mesh strategies, process optimization.\n\n```\n\"Why is my part warping?\" → causes, solutions, simulation checks\n\"What mesh type should I use?\" → midplane vs dual-domain vs 3D guidance\n\"How to reduce cycle time?\" → cooling optimization strategies\n```\n\n### `get_material_properties`\nMaterial property lookup. Returns Cross-WLF viscosity, Tait PVT, thermal, processing window, and mechanical data.\n\n**21 materials included:** ABS, PP Homo, PP Copo, PA6, PA66, PA66-GF30, PC, PC/ABS, POM, HDPE, LDPE, PMMA, PBT, PBT-GF30, PET, PS, HIPS, TPU, SAN, ASA, PPE/PS\n\n```\n\"PA66-GF30\" → Cross-WLF coefficients, Tait PVT, processing window 275-310°C, fiber effects\n\"PC\" → all properties or filter by group (viscosity, thermal, processing)\n```\n\n### `validate_process_parameters`\nChecks your process parameters against the material's processing window. Flags errors, warnings, and provides suggestions.\n\n```\nmaterial: \"ABS\", melt_temp_C: 280 → ERROR: exceeds max 260°C, risk of degradation\nmaterial: \"PA66\", mold_temp_C: 40 → WARNING: below min 70°C, poor crystallization\n```\n\n### `generate_simulation_spec`\nNatural language → structured simulation specification. Describe the part and get back analysis types, mesh recommendations, process conditions, and expected outputs.\n\n```\n\"Automotive dashboard panel in PC/ABS, 2.5mm wall, warpage analysis\"\n→ Fill+Pack+Cool+Warp sequence, dual-domain mesh, process conditions, expected outputs\n```\n\n### `compare_materials`\nSide-by-side comparison of 2-4 materials. Processing windows, thermal properties, mechanical data, and auto-generated key differences.\n\n```\n[\"abs-generic\", \"pc\", \"pa66-gf30\"] → comparison table with stiffness, shrinkage, heat resistance diffs\n```\n\n### `generate_dfm_checklist`\nDesign for Manufacturability checklist with pass/warn/fail ratings. Input part parameters and get 15+ DFM rule checks.\n\n```\nmaterial: \"ABS\", wall: 2mm, rib: 1.5mm, draft: 0.5°\n→ 16 checks: wall OK, rib WARN (75% ratio), draft WARN (below 1°), sink risk, venting...\n```\n\n## Examples\n\nAsk your AI assistant:\n\n- \"What are the Cross-WLF parameters for PA66-GF30?\"\n- \"I'm getting sink marks on my PC housing — what should I check?\"\n- \"Validate my process: ABS at 250°C melt, 70°C mold, 2mm wall\"\n- \"Generate a simulation spec for a PP container with 1.5mm walls\"\n- \"Compare ABS vs PC vs PA66-GF30 for an automotive connector\"\n- \"Run a DFM check: 2mm wall, 1.5mm ribs, 0.5° draft in PC\"\n- \"What mesh type should I use for a thick-walled POM gear (5mm)?\"\n- \"How do I fix warpage in a glass-filled PA66 connector?\"\n\n## Knowledge Coverage\n\n| Area | Coverage |\n|------|----------|\n| Materials | 21 grades with Cross-WLF, Tait PVT, thermal, mechanical, processing + comparison |\n| Defects | Short shot, flash, sink marks, warpage, weld lines, burn marks, jetting, splay, voids, flow marks |\n| Simulation | Mesh sensitivity, race tracking, cooling, overpacking, shear rate |\n| Process | Cycle time, gate location, V/P switchover, degradation, crystallization, fiber orientation |\n| DFM | Wall thickness, ribs, draft, radii, bosses, gating, tolerances, shrinkage, venting |\n| Meshing | Midplane, dual-domain, 3D — when to use, element sizing, quality metrics |\n\n## Compatible Software\n\nMoldSim MCP provides software-agnostic knowledge that applies to all major injection molding simulation packages:\n\n- **Autodesk Moldflow** — Adviser & Insight\n- **Moldex3D** — all editions\n- **CADMOULD** — Simcon\n- **SIGMASOFT** — Virtual Molding\n- **SolidWorks Plastics**\n\n## Tech Stack\n\n- **Runtime:** Node.js, TypeScript\n- **Search:** Qdrant vector database (local, embedded)\n- **Embeddings:** HuggingFace transformers\n- **Protocol:** Model Context Protocol (MCP)\n\n## License\n\nMIT\n",
