Calculator
MCP Server Calculator provides a simple mathematical expression evaluation service using Python's AST module for secure parsing and calculation. Built by He Jie, it exposes a single 'calculate' tool that safely evaluates mathematical expressions without using Python's built-in eval() function, supporting basic operations like addition, subtraction, multiplication, division, and exponentiation. The implementation uses FastMCP for server functionality and is packaged for easy installation via pip, making it ideal for workflows requiring quick calculations without leaving the conversation interface.
