Performs precise decimal arithmetic for AI agents over HTTP and standard I/O.
Sponsored
The Calculator tool provides a tiny yet powerful Model Context Protocol (MCP) server, offering exact decimal arithmetic operations for AI agents. It eliminates common floating-point errors and LLM math hallucinations by precisely handling additions, subtractions, multiplications, and divisions of number arrays. With flexible runtime precision control and dual transport options (HTTP and standard I/O), it seamlessly integrates into various AI applications, from Claude Desktop and LangChain agents to custom financial or scientific computation tools, all available via pre-built Docker images.
