Calculator Server Overview

The avisangle/calculator-server MCP server exposes 13 mathematical tools through MCP, covering arithmetic, scientific functions, expressions, statistics, conversions, and finance. It runs as a Go 1.21+ application over stdio or an MCP streamable HTTP endpoint with SSE support. Reach for it when an agent needs deterministic calculations or structured numeric analysis without an external API. The repository documents local build and run workflows, including configurable HTTP ports.
