`evaluate`

Pack: mathjs · Endpoint: https://gateway.pipeworx.io/mathjs/mcp

Evaluate mathematical expressions: arithmetic, algebra, trigonometry, statistics. Returns computed result. E.g., “2+2”, “sin(pi/2)”, “sqrt(16)”, “mean([1,2,3])”. Use when you need to calculate or simplify math.

Parameters

Name	Type	Required	Description
`expression`	string	yes	Mathematical expression to evaluate (e.g., “2 + 3 * 4”, “sqrt(16)”, “sin(pi/2)”, “det([1,2;3,4])“)

Example call

Arguments

{
  "expression": "2 + 3 * 4"
}
