What is Mcp Math Calculator?

Mcp Math Calculator is a Model Context Protocol server that provides AI clients with 100% accurate mathematical computation capabilities. It solves floating‑point precision issues (e.g., 0.1 + 0.2 = 0.3 exactly), supports large numbers, complex expressions, and over 300 scientific functions, all inside a sandboxed, secure environment.

How to use Mcp Math Calculator?

Install via npx (npx -y mcp-math-calculator) or globally (npm install -g mcp-math-calculator), then add its configuration to your MCP client’s JSON (e.g., claude_desktop_config.json). After restarting the client, the AI automatically invokes the calculate tool on math queries.

Key features of Mcp Math Calculator

Accurate arithmetic with no floating‑point errors.
Supports numbers beyond JavaScript’s safe integer range.
Handles parentheses and operator precedence in expressions.
Offers 300+ mathematical functions (trig, log, sqrt, etc.).
Sandboxed evaluation with no code‑injection risk.
Automatic 5‑second timeout to prevent runaway calculations.

Use cases of Mcp Math Calculator

Performing exact financial or scientific calculations where floating‑point errors are unacceptable.
Computing large number multiplication, exponentiation, or factorials beyond standard limits.
Evaluating compound expressions with multiple operations and functions.
Enabling AI assistants to solve math problems reliably without approximation.
Safely accepting user‑provided expressions in untrusted environments.

FAQ from Mcp Math Calculator

What does Mcp Math Calculator do?

It provides a single calculate tool that evaluates mathematical expressions with high precision, returning exact results for queries like 0.1 + 0.2 or 123456789 * 987654321.

How does Mcp Math Calculator handle floating‑point precision?

It uses the mathjs safe parser instead of eval(), which avoids JavaScript’s native floating‑point rounding errors and ensures results like 0.1 + 0.2 equal exactly 0.3.

What are the runtime requirements for Mcp Math Calculator?

The server runs on Node.js and is distributed as an npm package. It is invoked via npx or installed globally, requiring a standard Node.js environment.

Is Mcp Math Calculator secure?

Yes. It does not use eval(), runs expressions in a sandboxed environment, whitelists only safe mathematical functions, validates inputs, and enforces a 5‑second timeout plus a result size limit.

What expression functions are supported?

Supported operations include basic arithmetic (+, -, *, /, ^, %), parentheses, functions like sqrt, pow, abs, round, trigonometric functions, logarithmic functions, and constants (pi, e, tau, phi).
