Calculate metabolic rates inside Claude Desktop

The `get_bmr` tool calculates your basal metabolic rate using weight, height, age, and gender parameters. Claude Desktop executes this tool locally via stdio, feeding the raw calorie counts straight into your active chat. You get immediate, calculated baseline energy needs without switching to a web calculator with this MCP Server. For deeper daily tracking, the `get_tdee` tool expands this calculation to include your active habits. Claude Desktop maps this data instantly, allowing your agent to plan accurate caloric targets based on real physical metrics.

Build exercise routines with this MCP Server

The `get_exercises` tool searches a database of movements by target muscle, difficulty, and equipment type. This MCP Server lets your agent pull step-by-step instructions directly into your workspace. You can filter by beginner or expert levels to build custom routines on the fly. Combining this with the `get_sleep` tool helps you balance recovery and exertion. Claude Desktop analyzes your sleep adequacy alongside your training splits to ensure your routine remains sustainable.

Analyze nutrition and body composition

The `get_nutrition` tool retrieves macronutrient breakdowns for any food item per 100-gram serving. Claude Desktop parses the fat, protein, and carbohydrate data to build instant meal logs. You don't have to manually search food databases or copy-paste nutrition labels anymore. Tracking physical changes becomes straightforward with the `get_body_fat` tool. Your desktop agent processes your waist, neck, and height measurements to determine your body fat category instantly.
