Math Tools MCP

Prime factors, GCD and LCM, and basic statistics computed on the local machine. No network, no key.

This file is self contained. It reads public data only and never writes to the machine. All output is bounded and honest about what could not be fetched.

Tools

• prime_factors Prime factors.
• gcd_lcm GCD and LCM.
• stats Descriptive statistics.

Usage

npm install
npm run build
node dist/index.js

All computation happens locally. Values are bounded to keep results fast.

Premium tools

These tools need a license key:

• sequence_lookup
• evaluate_expression

Buy a key at https://mcp-marketplace.io/server/io-github-mrfentmen-math-tools-mcp and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "mcp_live_..." }

The key is checked against MCP Marketplace, cached for 24 hours, and keeps working offline once one check has succeeded. Every other tool on this server stays free.
