# Protein Needs Calculator MCP > Protein Needs Calculator helps you figure out exactly how much protein you need to hit your fitness goals. It takes your weight, how much you move, and your specific objectives like building muscle or losing weight into account. It even handles specific needs for things like pregnancy or aging. ## Overview - **Category:** health - **Price:** Free - **Tags:** protein, nutrition, fitness, diet, health-calculator ## Description You're trying to hit a specific body composition goal, but the math behind protein intake is annoying. It's not just a one-size-fits-all number. If you're lifting heavy, your needs are different than if you're just trying to stay healthy while staying active. This MCP takes the guesswork out of the math by letting your AI client handle the nutritional science. You don't have to go hunting for formulas or trying to remember if you should be aiming for a certain gram count based on your current weight. It looks at your activity level, your goals, and even your current life stage to give you a solid number. It's a huge help when you're building out a nutrition plan and need to know if your targets actually make sense for your body. Since Vinkius hosts this in their catalog, you can just plug it into your existing setup and let your agent do the heavy lifting of calculating these numbers for you. It turns a manual, research-heavy task into a quick conversation with your AI. ## Prompt Examples **Prompt:** ``` How much protein do I need if I weigh 80kg, am moderately active, and want to gain muscle? ``` **Response:** ``` Based on your weight of 80kg and moderate activity level, you should aim for approximately 128 grams of protein per day to support muscle gain. ``` **Prompt:** ``` Calculate protein for a 70kg person who is sedentary and focused on weight loss. ``` **Response:** ``` For a 70kg individual with a sedentary lifestyle focusing on weight loss, the recommended daily protein intake is 56 grams. ``` **Prompt:** ``` Is 100g of protein enough for an 85kg athlete? ``` **Response:** ``` No, 100g is not sufficient. For an 85kg person with high activity levels, the requirement exceeds 100g. ``` ## Capabilities ### Get daily protein totals Get a specific protein target in grams based on your weight and activity level. ### Check plan feasibility Find out if your current nutrition plan is actually realistic for your body. ### Adjust for high intensity Get higher protein targets for heavy lifting and active lifestyles. ### Support pregnancy needs Calculate specific requirements for people who are pregnant. ### Tailor for weight loss Get specific numbers for staying lean while maintaining muscle. ### Account for aging Get accurate protein targets for elderly users. ## Use Cases ### Checking if a goal is too high A bodybuilder wants to know if 200g of protein is too much for his 90kg frame.
