MCP Calculate Server

A mathematical calculation service based on MCP protocol and SymPy library, providing powerful symbolic computation capabilities.

Key Features

• Basic Operations: Addition, subtraction, multiplication, division, exponentiation
• Algebraic Operations: Expression expansion, factorization, simplification
• Calculus: Differentiation, integration (definite/indefinite), limit calculation
• Equation Solving: Algebraic equations, systems of equations
• Matrix Operations: Matrix inversion, eigenvalues/eigenvectors calculation
• Series Expansion: Taylor series expansion
• Special Functions: Trigonometric, logarithmic, exponential functions

Usage Examples

# Basic operations
"2 + 3*5" → 17

# Algebraic operations
"expand((x + 1)**2)" → x² + 2x + 1
"factor(x**2 - 2*x - 15)" → (x - 5)(x + 3)

# Calculus
"diff(sin(x), x)" → cos(x)
"integrate(exp(x), (x, 0, 1))" → E - 1
"limit(tan(x)/x, x, 0)" → 1

# Equation solving
"solve(x**2 - 4, x)" → [-2, 2]
"solve([x**2 + y**2 - 1, x + y - 1], [x, y])" → [(0, 1), (1, 0)]

# Matrix operations
"Matrix([[1, 2], [3, 4]]).inv()" → [[-2, 1], [3/2, -1/2]]
"Matrix([[1, 2, 3], [4, 5, 6]]).eigenvals()" → {9/2 - sqrt(33)/2: 1, 9/2 + sqrt(33)/2: 1}
