Advanced calculus, linear algebra, probability, and finance tools for AI agents, exposed via the Model Context Protocol (MCP).

Features

• Calculus: Symbolic derivatives/integrals, numerical Riemann sums, limits, volumes of revolution.
• Linear Algebra: Matrix multiplication, inversion, determinants, eigenvalues.
• Finance: Black-Scholes pricing, Option Greeks, Sharpe Ratio, Value at Risk (VaR), Cashflow schedules.
• Probability: Normal, Binomial, and Poisson distributions.
• Engineering: Numerical Laplace and Fourier transforms.
• Optimization: Newton-method root finding.
• Meta-Tools: describe_available_tools for agent discovery.

Installation

For AI Agents (Claude Code, Cursor, Cline, Roo Code)

Add the following to your MCP configuration:

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

Usage Examples for Agents

Calculus

• "Calculate the derivative of x^2 + sin(x)"
• "Find the area under x^3 from 0 to 2 using 1000 trapezoids"

Finance

• "Price a European call option with S=100, K=105, T=0.5, r=0.03, sigma=0.2"
• "Generate a monthly cashflow schedule for a $10,000 loan at 5% interest for 1 year"

Linear Algebra

• "Find the eigenvalues of the matrix [[1, 2], [3, 4]]"

Security & Reliability

• Safe Evaluation: Uses mathjs for expression parsing, avoiding dangerous eval().
• Input Validation: All parameters are strictly validated via Zod.
• Safety Caps: Numerical methods have hard caps on iterations and subintervals to prevent DoS.
• CVE Fixes: Dependencies updated to address known vulnerabilities (e.g., qs).
