## Description

This tool tackles one of medicine's most stressful calculations: figuring out the right dose when you only have a patient’s weight and a concentration ratio. Instead of juggling formulas on paper or relying on memory, this MCP handles the full dosing path for you. You input the key variables—the patient's mass, the prescribed dose rate, and the drug's current concentration. The system first calculates the total milligrams needed using `calculate_mass_requirement`. Next, it converts that required mass into the corresponding liquid volume via `convert_mg_to_ml`, and finally delivers the exact amount to administer using `calculate_full_liquid_dose`. It’s a critical safety check for weight-based dosing. By connecting this MCP through Vinkius, your AI client can provide instant, verifiable calculations right where you need them.

## Tools

### calculate_full_liquid_dose
Determines the single, final volume of liquid medication that needs to be administered to the patient.

### calculate_mass_requirement
Calculates the total required milligrams of medication based on the specific weight of the patient.

### convert_mg_to_ml
Converts a specified mass (milligrams) of medicine into the corresponding liquid volume in milliliters.

## Prompt Examples

**Prompt:** 
```
A patient weighs 22kg, and I need to administer an antibiotic at 15mg/kg. The vial is 7.5mg/mL. How much liquid should I draw up?
```

**Response:** 
```
**Dosing Calculation Report**

*   **Patient Weight:** 22 kg
*   **Target Dose Rate:** 15 mg/kg
*   **Vial Concentration:** 7.5 mg/mL

***Calculations:***
1.  **Total Mass Required:** 330 mg (22kg * 15mg/kg)
2.  **Volume Conversion:** 44 mL (330mg / 7.5mg/mL)

✅ **Final Liquid Dose to Administer: 44 mL**
```

**Prompt:** 
```
What is the required dose for a baby weighing 12kg, if the drug needs to be 8mg/kg and the concentration is 50mg/mL?
```

**Response:** 
```
**Dosage Calculation Report**

*   **Patient Weight:** 12 kg
*   **Target Dose Rate:** 8 mg/kg
*   **Vial Concentration:** 50 mg/mL

***Calculations:***
1.  **Total Mass Required:** 96 mg (12kg * 8mg/kg)
2.  **Volume Conversion:** 1.92 mL (96mg / 50mg/mL)

✅ **Final Liquid Dose to Administer: 1.92 mL**
```

**Prompt:** 
```
I need to administer 400 milligrams of drug, but the concentration is 10mg/mL. What volume do I draw up?
```

**Response:** 
```
**Dosing Calculation Report**

*   **Target Mass:** 400 mg
*   **Vial Concentration:** 10 mg/mL

***Calculations:***
1.  **(Mass is already set)**
2.  **Volume Conversion:** 40 mL (400mg / 10mg/mL)

✅ **Final Liquid Dose to Administer: 40 mL**
```

## Capabilities

### Determine required total milligrams
Calculates the overall mass of medication needed by multiplying the patient's weight by the prescribed dosage rate.

### Convert drug mass to liquid volume
Takes a calculated target milligram amount and converts it into the precise milliliters (mL) required for administration based on concentration.

### Calculate final administered dose
Determines the single, actionable liquid volume that must be drawn up and given to the patient.

## Use Cases

### Calculating Pediatric IV Drip Rates
A pediatrician needs to administer an antibiotic at 12mg/kg to a child weighing 18kg. The drug is supplied as 60mg/mL. Asking your agent solves this: first, calculate the total mass (216mg). Then, convert that to volume (3.6mL), providing the perfect IV drip rate instantly.

### Protocol Change Verification
A nurse needs to switch a drug protocol from 10mg/kg to 8mg/kg for an adult patient weighing 75kg. Instead of recalculating everything, the agent uses `calculate_mass_requirement` and then runs the new figure through `calculate_full_liquid_dose` to verify the precise change in dosage.

### Emergency Triage Dosing
During a rapid triage event, you only have the patient's weight (105kg) and the desired dose rate. The agent calculates the initial milligrams needed using `calculate_mass_requirement`, letting the team know exactly how much drug to prepare immediately.

## Benefits

- Stop risking errors. Use `calculate_mass_requirement` to immediately determine the total milligrams needed, regardless of how complex the weight-based calculation is.
- Save time on conversions. The `convert_mg_to_ml` tool handles unit translation instantly, taking you from a measured mass to the volume required for administration.
- Get one final answer. By running through `calculate_full_liquid_dose`, you get the single, actionable milliliter volume without having to manually calculate the last step.
- Boost patient safety in pediatrics. The calculator is designed specifically to manage complex weight-based dosing scenarios common with children's medicine.
- Reduce chart errors. You eliminate the need for multiple manual calculations across different pages of a drug protocol, keeping your documentation clean and precise.

## How It Works

The bottom line is that your agent handles the entire chain of calculations, from weight input to final volume output, ensuring maximum accuracy and saving time during critical care protocols.

1. Provide your AI client with three pieces of data: the patient's weight, the drug’s prescribed dosage rate (e.g., mg/kg), and the concentration in the vial (mg/mL).
2. The MCP first calculates the total required milligrams using `calculate_mass_requirement`. Then, it takes that mass and converts it to a liquid volume using `convert_mg_to_ml`.
3. Finally, it runs the result through `calculate_full_liquid_dose`, giving you one definitive number: the exact milliliters to administer.

## Frequently Asked Questions

**How does the Weight to Liquid Dose Calculator handle pediatric dosing?**
The calculator is optimized for pediatrics. You simply provide the child’s weight and the drug's dose rate, and it automatically runs all necessary conversions to tell you the exact milliliter volume needed.

**Can I use this MCP if the concentration changes in the vial?**
Yes. Just provide the current concentration (mg/mL) along with the weight and dose rate. The calculator will adjust every step, ensuring your final liquid volume is accurate for the drug you have on hand.

**Is this better than using a standard online dosing chart?**
It's much more reliable because it runs all three steps—mass calculation, unit conversion, and final dose determination—in one controlled environment. You don't have to trust multiple separate sources.

**What kind of calculations does the Weight to Liquid Dose Calculator perform?**
It performs clinical pharmacology math: it takes patient weight, calculates the total milligrams needed for a dose rate, and then converts that milligram amount into the precise milliliters you need to administer.

**Does this MCP work if I don't know the specific drug name?**
No, it requires three inputs: patient weight, the prescribed dosage rate (mg/kg), and the concentration. It doesn't care about the drug name; it just handles the math.
