CAD prompts that need real density / mechanical properties stop\n> hallucinating.\n\n## Install\n\nZero-install via `uvx`:\n\n```json\n{\n  \"mcpServers\": {\n    \"pymat\": {\n      \"command\": \"uvx\",\n      \"args\": [\"pymat-mcp\"]\n    }\n  }\n}\n```\n\nThat's it. `uvx` fetches `pymat-mcp` (which transitively pulls\n`py-materials`) and runs it in an isolated venv per session.\n\nFor a pinned version: `\"args\": [\"pymat-mcp@0.1.0\"]`.\n\nFor programmatic use, `pip install pymat-mcp` works too — the package is\nfully a normal Python module.\n\n## Tools\n\n| Tool | What |\n|---|---|\n| `search_materials(query, limit=10)` | Fuzzy lookup → list of brief rows |\n| `get_material(key_or_name)` | Full property dump (mechanical / thermal / electrical / optical / manufacturing / compliance / sourcing) + visual identity |\n| `list_categories()` | Top-level groups (aluminum, stainless, lyso, …) |\n| `list_grades(material)` | Children (grades / tempers / treatments) |\n| `compute_mass(material, volume_mm3)` | Mass in grams from a build123d-style volume |\n| `get_appearance(material)` | Vis dict — mat-vis identity, finishes, PBR scalars |\n| `to_threejs(material, finish=None)` | Three.js MeshPhysicalMaterial init dict |\n| `to_gltf(material, finish=None)` | glTF 2.0 material node |\n| `compare_materials(keys, properties=None)` | Side-by-side property comparison |\n\nAll tools are read-only. Errors come back as `{\"error\": \"...\", \"did_you_mean\": [...]}` rather than exceptions.\n\n## Example agent prompts\n\n- *\"What's the yield strength of 17-4 PH H1025?
