Expr-Lang
MCP Expr-Lang provides a powerful expression evaluation tool for Claude Desktop, integrating the expr-lang engine for complex data manipulations directly within Claude conversations. Developed by Ivan Saorin, this Go-based server enables users to evaluate mathematical expressions, transform arrays and objects, perform string operations, and apply conditional logic through a simple interface. The implementation supports a wide range of operations from basic arithmetic to complex data sorting and filtering, making it particularly useful for data analysis, calculations, and transformations without leaving the AI assistant environment.
