  • Data: B, KB, MB, GB, TB
  • Time: s, min, h, d, week
  • Speed: m/s, km/h, mph, knots
statistics

Statistical analysis on datasets: mean, median, mode, variance, standard deviation, min, max, range, percentile, correlation between two arrays, and a full summary mode.

format_number

Format numbers as: currency ($1,234.56), percentage, scientific notation, binary, octal, hexadecimal, significant figures, or with thousands separators.

{
  "mcpServers": {
    "math-tools": {
      "command": "node",
      "args": ["path/to/mcp-math-tools/dist/index.js"]
    }
  }
}

Calculate: 2 * (3 + 4) ^ 2 returns 98

Convert: 100 from km/h to mph returns 62.137...

Statistics: summary of [1, 2, 3, 4, 5] returns mean, median, mode, variance, etc.

Format: 1234567.89 as currency returns $1,234,567.89
