Scientific Calculator

Scientific Calculator

A checked calculator the model must call instead of doing the maths itself. Each tool takes validated inputs and returns a numeric or symbolic result plus the formula or method that produced it — school arithmetic, algebra, calculus, matrices, units, physics, chemistry, electrical engineering, programmer conversions, and India-shaped finance (EMI, SIP, GST).

Registry name	ai.saifs/scientific-calculator
Endpoint	https://scientific-calculator-mcp.saifs.ai/mcp
Transport	Streamable HTTP (remote, nothing to install)
Auth	OAuth 2.1 — PKCE (S256) and dynamic client registration; your client opens a sign-in page on first use
Publisher	SAIFS AI

Install

VS Code / GitHub Copilot

Add to .vscode/mcp.json (workspace) or your user mcp.json:

{
  "servers": {
    "saifs-scientific-calculator": {
      "type": "http",
      "url": "https://scientific-calculator-mcp.saifs.ai/mcp"
    }
  }
}

Then start the server from the MCP view and sign in when prompted.

Claude (claude.ai, Desktop)

Claude Code

claude mcp add --transport http saifs-scientific-calculator https://scientific-calculator-mcp.saifs.ai/mcp

Any other MCP client

Point it at https://scientific-calculator-mcp.saifs.ai/mcp using the Streamable HTTP transport. The server returns 401 with a WWW-Authenticate: Bearer … resource_metadata=… challenge, so OAuth-aware clients sign in automatically.

Tools

Named handlers cover these domains (symbolic work via SymPy; finance, physics and chemistry return the closed-form formula with the number):

Domain	What it covers
Basic & scientific	Arithmetic, percentage, fractions, ratios, averages, expressions, trig, logs, roots, factorial
Geometry	2D shapes, 3D solids, surface area and volume
Algebra	Linear, quadratic, cubic and polynomial roots, systems, inequalities, factor, expand, GCD/LCM
Statistics	Mean, variance, percentiles, combinations, binomial and normal probability
Calculus	Derivatives, integrals, limits, Taylor series, critical points, Simpson / trapezoidal quadrature
Matrix & vector	Inverse, determinant, eigenvalues, rank, dot and cross product
Units	Length, weight, area, volume, temperature, time, speed, pressure, energy, power
Physics & electrical	Kinematics, F = ma, Ohm’s law, work, energy, waves, resistors, AC reactance
Finance (India-shaped)	Simple / compound interest, EMI, SIP, GST, CAGR, profit/loss
Chemistry	Molar mass, moles, molarity, dilution, pH, ideal gas law, periodic table (Z = 1–118)
Programmer & dates	Base convert, bitwise, ASCII, date difference, age, leap year

Example prompts

• “Solve 2x² − 5x − 3 = 0 and show the quadratic formula.”
• “What is the EMI on a ₹12,00,000 home loan at 8.5% for 20 years?”
• “Differentiate sin(x²) and then evaluate the definite integral of x² from 0 to 3 with Simpson’s rule.”
