# BMI Clinical Calculator MCP > BMI Clinical Calculator provides three essential metabolic health metrics in one go. It calculates Body Mass Index (BMI), estimates ideal body weight using established formulas like Devine and Hamwi, and assesses candidacy for bariatric surgery based on clinical criteria. ## Overview - **Category:** healthcare - **Price:** Free - **Tags:** bmi, clinical, anthropometry, bariatric, health ## Description This tool gives clinicians a fast way to run a full anthropometric assessment. Instead of pulling up multiple guidelines or manually running separate calculations, you get a holistic view right away. It calculates your patient’s BMI while simultaneously assigning WHO classifications and metabolic risk categories. Need an idea of what a healthy weight range looks like? The system estimates ideal weights using several established clinical formulas. Plus, it checks if the patient meets key NIH criteria for bariatric surgery. Since this MCP lives on Vinkius, you connect your preferred AI client once and get access to hundreds of other specialized tools, keeping all your medical assessment needs in one place. ## Tools ### calculate_ideal_body_weights Estimates a person's healthy target weight using several common clinical formulas. ### compute_bmi_metrics Calculates the Body Mass Index and provides related, clinically relevant health metrics. ### evaluate_bariatric_eligibility Checks a patient's stats against established guidelines to see if they qualify for bariatric surgery. ## Prompt Examples **Prompt:** ``` Calculate the BMI metrics for a person weighing 95kg and 175cm tall. ``` **Response:** ``` The calculated BMI is 31.0, which falls under the Obesity Class I category according to WHO standards. The ASMBS metabolic risk category is also identified. ``` **Prompt:** ``` What is the ideal body weight for a female who is 160cm tall? ``` **Response:** ``` Using clinical formulas, the estimated ideal weights are: Devine: 52.2kg, Hamwi: 51.4kg, and Robinson: 50.8kg. ``` **Prompt:** ``` Is a patient with a BMI of 36 and hypertension eligible for bariatric surgery? ``` **Response:** ``` Yes, the patient is eligible for surgery because they meet the NIH criteria of having a BMI ≥ 35 with existing comorbidities. ``` ## Capabilities ### Calculate standard BMI metrics Determines the patient's Body Mass Index (BMI) and assigns classifications like WHO status or ASMBS risk categories. ### Estimate healthy weight ranges Uses multiple clinical formulas to provide estimated ideal body weights for different demographic groups. ### Screen bariatric eligibility Evaluates a patient’s metrics against standard NIH criteria to determine surgical candidacy. ### Assess metabolic risk profile Generates a multi-faceted view of the patient's weight status, going beyond simple BMI numbers. ## Use Cases ### Initial patient intake screening A PCP enters a new patient's height and weight. The agent runs `compute_bmi_metrics` to get the basic score, then uses `calculate_ideal_body_weights` to establish their healthy range, completing the initial risk assessment in seconds. ### Assessing high-risk obesity A specialist needs to know if a patient with severe weight issues is ready for surgery. They run `evaluate_bariatric_eligibility` after verifying the BMI score, getting an immediate yes/no answer based on clinical guidelines. ### Tracking metabolic changes over time A dietitian compares a patient's weight today versus last month. They use `compute_bmi_metrics` to see how the change affects their WHO class, ensuring the plan is hitting key metrics. ## Benefits - Stop guessing about weight status. The `compute_bmi_metrics` tool gives you standardized BMI scores and WHO classifications instantly. - Compare multiple formulas at once. Use the `calculate_ideal_body_weights` tool to see target weights using Devine, Hamwi, and Robinson metrics side-by-side. - Determine candidacy quickly. The MCP runs a full assessment against NIH criteria so you know right away if a patient qualifies for bariatric consideration. - Streamline your charting process. Instead of three separate calculations, this tool gives you one cohesive clinical profile. - Minimize risk. By combining the metrics from all tools, you get a deeper picture than any single number could provide. ## How It Works The bottom line is that you get three full-spectrum metabolic reports without ever changing tools or running separate calculations. 1. Input the patient’s height and current weight into the system. 2. The MCP runs calculations for BMI, estimates ideal weights using multiple formulas (Devine, Hamwi, Robinson), and checks against bariatric eligibility criteria. 3. You receive a comprehensive clinical report detailing all calculated metrics and risk assessments. ## Frequently Asked Questions **How do I use compute_bmi_metrics to assess a patient?** You provide the system with the patient's height and weight. The MCP calculates the BMI score, assigns it a WHO classification, and identifies metabolic risk categories in one step. **What does calculate_ideal_body_weights do?** This tool estimates what a healthy weight range should be. It runs several established clinical formulas (like Devine and Hamwi) so you get multiple reference points for comparison. **Does evaluate_bariatric_eligibility just check BMI?** No, it checks against a broader set of NIH criteria. It looks at the patient's metrics alongside other factors to give a proper assessment of surgical candidacy, not just based on weight. **Can I combine all three tools in one prompt?** Yes, that’s the point of this MCP. You send your agent one request for height and weight, and it runs all three assessments—BMI, ideal weight, and eligibility—in a single workflow. **If I use imperial measurements with compute_bmi_metrics, does it automatically convert them?** No, you must provide height and weight in kilograms and centimeters. If your client sends inputs using pounds or inches, the calculation will fail, so make sure to standardize your data first. **When compute_bmi_metrics returns a classification (like Obesity Class I), does it explain what that means clinically?** The tool reports the standard WHO and ASMBS categories but doesn't provide specific medical commentary. You should use the calculated metrics alongside established clinical guidelines for full interpretation. **Are there any rate limits or restrictions when I run multiple calculations using calculate_ideal_body_weights?** The MCP supports high-volume usage, but consistent excessive calls can trigger temporary throttling. If you hit a limit, wait five minutes and try again. **Besides BMI, what other information is required for evaluate_bariatric_eligibility?** Eligibility requires more than just current weight or BMI. You must include existing comorbidities and specific risk factors so the tool can check against the full NIH criteria.
