Tool nameconvert_power

Request

Send the request as JSON. MCP clients pass the same fields as tool arguments.

cURLshell

curl -X POST https://roaduser.tools/api/v1/power/convert \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "content-type: application/json" \

}'

Request bodyjson

{
  "value": 150,
  "from": "kw",
  "to": "hp"
}

Response

REST wraps the calculation result in the standard success envelope. MCP returns the same calculation data as structured tool output.
