@yasogan/math-mcp - Mathematical Model Context Protocol Server

Problem Statement

AI agents (Claude, OpenCode, Cursor, etc.) often need to perform mathematical calculations but lack built-in mathematical capabilities. Users must either rely on the agent’s limited math knowledge or manually perform calculations outside the agent environment. There’s a need for a standardized way to give mathematical superpowers to any MCP-compatible AI agent without requiring custom code from the agent side.

Solution Architecture

@yasogan/math-mcp implements a comprehensive Model Context Protocol server that exposes 8 mathematical tools through a standardized interface. The server bridges the gap between AI agents and mathematical computation libraries, providing:

• Unified Interface: Single MCP server exposing 8 distinct mathematical tools
• Symbolic Computation: Support for both numeric (mathjs) and symbolic (Algebrite) evaluation modes
• Comprehensive Coverage: Arithmetic, algebra, calculus, linear algebra, statistics, probability, and unit conversions
• Zero-Configuration: Agents can use tools immediately without writing mathematical code

Technical Implementation

Core Components

1. MCP Server Foundation: Built on @modelcontextprotocol/sdk v1.29.0
2. Tool Registry: 8 distinct mathematical tools with typed interfaces
3. Expression Parser: Supports LaTeX-like mathematical syntax via @scicave/math-latex-parser
4. Computation Backends:
   • mathjs v15.2.0 for numeric computations
   • algebrite v1.4.0 for symbolic algebra
5. Error Handling: Comprehensive validation and error reporting for malformed inputs
6. Type Safety: Full TypeScript implementation with strict type checking

Tool Categories

1. Basic Arithmetic & Evaluation

• evaluate: Computes mathematical expressions with mode: "numeric" | "symbolic"
• Examples: 2^10, sin(pi/4), derivative("x^3", "x"), integrate(x^2, x, 0, 1)

2. Algebraic Operations

• solve: Solves equations for variables (returns all solutions including complex)
• simplify: Simplifies expressions using mathematical identities
• factor: Factors polynomials into irreducible components
• expand: Expands factored expressions into polynomial form

3. Linear Algebra

• matrix: 13 matrix operations including:
  • Determinant, inverse, transpose, eigenvalues, eigenvectors
  • Matrix arithmetic (add, subtract, multiply)
  • Vector operations (dot product, cross product)
  • Matrix properties (rank, norm, trace)

4. Statistics & Probability

• statistics: 24 statistical operations including:
  • Descriptive statistics (mean, median, mode, std, variance)
  • Probability distributions (normal, binomial, Poisson, t, chi-squared)
  • Linear regression with auto-indexing

5. Unit Conversions

• units: Converts between physical units:
  • Length (km, miles, m, ft, in)
  • Mass (kg, lb, g, oz)
  • Temperature (degC, degF, K)
  • Pressure, energy, speed, area

Key Implementation Details

Expression Syntax

• Arithmetic: 2^10, 3 + 4 * 2
• Trigonometry: sin(pi/4), cos(30 deg)
• Algebra: x^2 - 4 = 0, (x+1)^3
• Calculus: derivative("x^3", "x"), integrate(x^2, x, 0, 1)
• Complex Numbers: 2+3i, sqrt(-1)
• Matrices: det([[1,2],[3,4]]), inv([[4,7],[2,6]])

Tool Integration Pattern

// Agent-side usage (no code required)
matrix({
  op: "determinant",
  a: [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9],
  ],
});
// Returns: 0

solve({ equation: "x^2 - 4 = 0", variable: "x" });
// Returns: ["2", "-2"]

  },
  {
    capabilities: {
      tools: {
        // 8 tool definitions with schemas
