Sodium Deficit & Correction Rate (ODS-Safe)
Calculate the total body sodium deficit and safe correction rate to prevent ODS. Na⁺ deficit = TBW × (Target − Measured). Default 8 mmol/L/24h for chronic; 12 mmol/L/24h for acute symptomatic. 3% NaCl volume estimated. Derived from Adrogué NEJM 2000, Verbalis 2013, Spasovski 2014, Sterns 2018, and MDCalc. Not medical advice.

}List available tools
After connecting to the SSE endpoint, list the exposed tools:
tools/list
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}Call this tool
Invoke the tool by its id, passing arguments built from its parameters:
tools/call
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "sodium-deficit-calculator",
"arguments": {

}
}
}Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
