Calculator

A straightforward arithmetic server that exposes four basic operations: add, subtract, multiply, and divide. The performance stats show add gets called most often (3,145 times), which makes sense for cumulative workflows. It runs over HTTP transport and maintains 99.8% uptime with a 2.5 second p50 latency. Reach for this when you need Claude to handle math without hallucinating numbers or when you're building agents that need reliable calculation as a building block. The usage is spread across Smithery's platform and Claude Code integrations, suggesting it works well as a foundational capability in larger workflows where you need verifiable arithmetic instead of LLM approximation.
