Milliequivalent Converter (mEq ↔ mg / mmol)
Convert mEq ↔ mg/mmol (or mEq/L ↔ mmol/L, mg/L) from molecular weight and valence: mEq = mmol × valence, mg = mmol × MW. 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": "milliequivalent-converter",
"arguments": {
"value": 20,
"unit": "mEq",
"mw": 74.55,
"valence": 1,
"decimalPlaces": 2
}
}
}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).
