Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Use this tool to CALCULATE a 3D printing price.

This tool does NOT create an order; it returns part_price / total / order_url. Output is desensitized (no unit prices).

}🟢search_materials(query, category_hint, process_filter, limit)
Use to resolve a user's material description (industry grade name like 'PA12', a colloquial term like 'nylon', a Chinese term, or a vague description) into concrete materials.csv entries. Unlike compare_materials/find_equivalent_materials (which need an exact known ID), this tool accepts messy input and returns a ranked list of candidates — use it as the first step when you don't already know the exact material_id. If multiple candidates come back, ask the user to pick one rather than guessing. Optionally narrow by category_hint (Plastic/Metal/Rubber/Resin/Powder Metals/Powder Polymers) or process_filter (e.g. 'Selective Laser Sintering', 'SLS', 'Injection Molding') when the context already implies a manufacturing process.
