Registration alone is not a production-quality guarantee. |\n| Browser execution | Automatic updates after valid input or file selection. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nAll flours together are the 100% basis. Starter should be split into flour and water before entering an overall formula. Calculated on your device. Changing units keeps the entered numbers.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `flours` | Flours and their weights | textarea | \"Bread flour = 400\\nRye flour = 100\" |  |\n| `ingredients` | Other ingredients and their weights | textarea | \"Water = 350\\nSalt = 10\" |  |\n| `massUnit` | Mass unit | select | \"g\" | Allowed: g, kg, oz, lb |\n| `targetFlour` | Target total flour weight | number | 1000 | min=0 max=100000000 step=any |\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nUp to 50 flour lines and 50 other ingredient lines, each with a unique name and positive weight. Every weight uses the selected unit.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"bakers-percentage-calculator\",\n  \"category\": \"calculators\",\n  \"built\": true,\n  \"requirements\": \"Up to 50 flour lines and 50 other ingredient lines, each with a unique name and positive weight.
