About Ultimath Mcp
Stop hallucinating numbers. An MCP server that runs every math expression through four independent numeric engines in parallel and returns all four results side by side — so when they disagree, you know the answer is numerically unreliable.

Overview
What is Ultimath Mcp?
Ultimath Mcp is an MCP server that evaluates every math expression through four independent numeric engines in parallel—multiprecision, exact decimal, IEEE-754 double, and interval arithmetic—and returns all four results side by side. It is designed for developers who need to detect when a numeric answer is unreliable due to floating-point or algorithmic differences.
How to use Ultimath Mcp?
Obtain a free API key at https://ultimath.ai, then add the server to your MCP client configuration (e.g., Claude Desktop) using the command npx -y ultimath-mcp and the environment variable ULTIMATH_API_KEY. The server exposes two tools: evaluate (run an expression on all four engines) and list_functions (show all available functions, optionally filtered by category). Multiplication must be explicit (use *; adjacency like 2pi is an error).
Key features of Ultimath Mcp
- Four parallel numeric engines for cross‑comparison
- Evaluate expressions with arithmetic, trig, exp/log, roots, powers, factorial, complex numbers, and alternate bases
- List all available functions with categories and descriptions
- Explicit multiplication required (no implicit adjacency)
- Supports constants like pi, e, and golden ratio PHI
- Open‑source, runs via npx with no permanent installation
Use cases of Ultimath Mcp
- Checking numerical stability of a calculation across different arithmetic models
- Debugging precision issues in scientific or financial computations
- Teaching numerical analysis concepts by comparing results side by side
- Verifying results in applications where rounding error could cause problems
FAQ from Ultimath Mcp
What operations does the evaluate tool support?
It supports arithmetic, trigonometric functions (sin, cos, tan), exponentials and logarithms (exp, ln, log), roots and powers (sqrt, x^y), factorial, complex numbers (e.g., 3+2i), alternate bases (0xFF, 0b1010), and constants (pi, e, PHI).
How do I multiply two terms in an expression?
Multiplication must be explicit: use the * sign (e.g., 2*pi, 2*sin(x), (a+b)*(c+d)). Writing adjacent terms like 2pi will cause an error.
What are the system requirements for Ultimath Mcp?
You need Node.js version 18 or later and a free API key from https://ultimath.ai. The server runs on demand via npx.
Where do I get an API key?
Visit https://ultimath.ai and sign up for a free API key. Then set it as the ULTIMATH_API_KEY environment variable in your MCP client configuration.
Does Ultimath store my expressions or use them for training?
No. Ultimath stores only a hash of your API key and basic usage metrics for service operation and security. Expressions are evaluated and not retained for training. See the full privacy policy at https://ultimath.ai/privacy/.
