LLMs are notoriously bad at arithmetic, frequently struggling with floating-point math, operator precedence, and complex multi-step equations (e.g. 0.1 + 0.2). This MCP offloads mathematical computation to mathjs, guaranteeing strict, deterministic precision.

The Superpowers

  • Flawless Evaluation: The AI just sends a string like (1.5 * 3) / 0.2 and gets the mathematically perfect answer instantly.
  • Precision Rounding: Explicitly force the rounding of financial or scientific numbers to the exact decimal places requested without hallucinations.
  • Native Speed: Executes entirely within the edge V8 isolate with no external API latency.

2 tools expose this connector's capabilities to your AI agent.

calculate_expression

Safely evaluates complex mathematical expressions (e.g. "1.2 * (2 + 4.5)") deterministically using mathjs

round_value

Pass the expression as a string (e.g. "2^8 + sqrt(144)") and the engine computes the exact result using mathjs. Rounds a float value to a specific number of decimal places

See how to talk to your AI agent using Math Evaluation Engine.

Safely calculate `4.5 * (10 / 3)` and avoid floating point inaccuracies.

✅ **Math Result:** `15`

Evaluate this complex user-submitted equation: `(2^4 + 10) / 2`.

✅ **Math Result:** The evaluated result is exactly `13`.

Round the floating point number `14.55556` down to exactly 2 decimal places.

✅ **Rounded Result:** `14.56`

Because LLMs are probabilistic text generators, not calculators.
