Evaluate math on Deterministic Math Expression Evaluator
Safely evaluates a string-based mathematical expression using a strict AST parser. Avoids LLM hallucinations on complex algebra
What the Deterministic Math Expression Evaluator MCP Server unlocks
When LLMs try to solve complex algebraic strings (e.g., (15 + 4) * 2 / sqrt(9)), they often guess the mathematical order of operations, leading to hallucinations. While one solution is to pass the string into Javascript's eval() function, this creates a massive security vulnerability for injection attacks. The Expression Evaluator MCP resolves this by implementing a pure, secure Recursive Descent Parser (AST) to evaluate mathematical strings deterministically.
The Superpowers
- Order of Operations (PEMDAS): Impeccably resolves parentheses, exponents, multiplication, and addition in the exact mathematical order.
- Zero-Vulnerability Execution: Employs a custom Lexer and AST (Abstract Syntax Tree) instead of
eval(). Malicious code injections are physically impossible to execute. - Built-in Math Functions: Supports trig and algebraic functions right out of the box:
sqrt,abs,sin,cos,tan,log,exp,round,ceil,floor. - Zero-Dependency Architecture: Pure JS runtime execution guarantees absolute speed without external bloated parsing packages.
Frequently asked questions about the Deterministic Math Expression Evaluator MCP Server
Why not just use the standard JavaScript `eval()` function?
Using eval() exposes your agentic infrastructure to remote code execution (RCE) vulnerabilities. If a user prompts the AI to evaluate process.exit(), eval() will shut down your server. This MCP parses strings into an Abstract Syntax Tree (AST), making malicious execution impossible.
Does it support complex nested parentheses?
Yes. The recursive descent parser handles infinite levels of nested parentheses, ensuring the core order of operations (PEMDAS) is strictly enforced.
What happens if there's a division by zero?
The math engine intercepts infinite states like Division by Zero or invalid syntax, safely returning a gracefully handled error string rather than crashing the tool.
