Large Language Models are brilliant at reasoning, but they notoriously hallucinate when performing exact mathematics. The Fundamental Math MCP Server solves this by providing your autonomous agents with a deterministic, zero-latency computational engine.

The Superpowers

  • Zero Hallucinations: Guarantees 100% mathematical accuracy for critical workflows like finance and statistics.
  • Privacy First (Local): Executes purely in local JavaScript. No API calls, no data leaves your secure enclave.
  • The Classic Rule of Three: Easily solve proportional problems (if A is to B, then C is to X) without complex prompting.
  • Essential Toolkit: Built-in tools for percentages, square roots, exponential powers, and factorials.

Stop relying on probabilistic models for exact numbers. Equip your agent with a real calculator.

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

calculate_factorial

Calculates the factorial of a non-negative integer

calculate_percentage

Calculates the percentage of a given total value

calculate_power

Calculates the base raised to the exponent power

calculate_rule_of_three

Solves a simple rule of three (proportionality)

calculate_square_root

Calculates the square root of a given number

See how to talk to your AI agent using Fundamental Math.

I have a total budget of 4500 and I want to allocate 17.5% to marketing. Calculate the exact value.

Using the calculate_percentage tool: The exact value for 17.5% of 4500 is 787.5.

If an ad campaign generated 120 leads with a $500 investment, how many leads can I expect with a $2500 investment?

Using the calculate_rule_of_three tool (A=500, B=120, C=2500): You can expect exactly 600 leads with a $2500 investment.

Calculate the factorial of 12 for my probability distribution script.

Using the calculate_factorial tool: The factorial of 12 (12!) is exactly 479,001,600.

AI models predict the next token; they don't actually compute math. This leads to subtle and dangerous errors in calculations. This MCP forces the AI to use a deterministic JavaScript engine, ensuring absolute precision.
