Scientific Calculator MCP Server

A production-ready Model Context Protocol (MCP) server providing advanced mathematical calculation capabilities for AI models. Supports symbolic math (SymPy), numerical computing (NumPy/SciPy), data analysis (pandas), and image processing.

Quick Start

1. Install Dependencies

pip install sympy numpy scipy pandas

Server Configuration

Add to your Claude Desktop config file:

{
  "mcpServers": {
    "scientific-calculator": {
      "command": "mcp-calculator",
      "args": [],
      "env": {}

  "mcpServers": {
    "scientific-calculator": {
      "command": "mcp-calculator",
      "args": [],
      "env": {}
    }
  }
}

macOS/Linux Example:

Usage Examples

from calculator import CALCULATOR_TOOLS

# Derivative: d(x³)/dx = 3x²
result = CALCULATOR_TOOLS['symbolic_derivative']('x**3', 'x')

# Solve: x² - 4 = 0
result = CALCULATOR_TOOLS['solve_equation']('x**2 - 4', 'x')

# Eigenvalues of matrix
import numpy as np
A = [[1, 2], [3, 4]]
result = CALCULATOR_TOOLS['numpy_linear_algebra'](A, 'eigenvalues')

# Integrate: ∫ x² dx from 0 to 1
result = CALCULATOR_TOOLS['symbolic_integral']('x**2', 'x', 0, 1)

Model Usage Policy

• Every numeric or symbolic calculation must be delegated to the tools (via MCP tools/call or direct CALCULATOR_TOOLS[...]), never hand-compute inside the model response.
• Reasoning flow: pick the right tool → prepare JSON-safe inputs → call the tool → present the tool output (with minimal post-processing only for formatting).
• If a step would require arithmetic, call a tool instead (e.g., use numpy_linear_algebra for matrices, symbolic_* for algebra, scipy_* for calculus/optimization).
• Avoid approximations unless the tool returns them; do not estimate values manually.

Prompting Playbook (Advanced Problems)

• Restate the task, list the required sub-calculations, and map each to a tool.
• For matrices, always supply matrix_a (and matrix_b when needed) as JSON arrays to numpy_linear_algebra.
• For calculus/ODE/PDE, convert expressions to plain strings (SymPy-compatible) before calling symbolic_* or scipy_* tools.
• After each tool call, reuse its exact output for subsequent steps—no manual arithmetic in between.
• When summing or solving, prefer tool outputs as inputs to the next tool (e.g., eigenvalues → use in later steps instead of recomputing).
• If the user asks for a result, return: the tool(s) called, inputs used, and the tool outputs; avoid “mental math.”
