What it does

laszlopere/mcp-abacus is a Model Context Protocol (MCP) server that provides advanced calculator capabilities for AI assistants. It evaluates mathematical expressions with precision tracking, offering three arithmetic modes: fixedpoint arithmetic, IEEE754 double precision, and exact rational arithmetic. The tool labels every result as either exact or inexact, helping users understand the precision of their calculations.

How to set up

Installation is straightforward using uvx: uvx mcpabacus. As an MCP server, it integrates with compatible AI platforms like Claude and other MCP-enabled tools. No network connection is required as it runs completely offline.
