Flywheel Energy Storage Calculator
Calculate the kinetic energy stored in a flywheel. E = ½·I·ω², ω = 2π·n/60. Enter the moment of inertia directly, or compute it from flywheel mass and radius (I = ½·m·r²). Supports J/kJ/Wh.

| Name | Type | Required | Description |
|---|---|---|---|
| I | number | No | Optional. If omitted, it is computed from flywheel mass and radius using I = ½·m·r². |
| n | number | Yes | — |
| m | number | No | Optional. Used with radius to derive I when I is not provided. |
| r | number | No | Optional. Used with mass to derive I when I is not provided. |

}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": "flywheel-energy-storage",
"arguments": {
"I": 2,
"n": 3000,
"m": 0,
"r": 0,
"energyUnit": "J",
"decimalPlaces": 4
}
}
}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).
