Summary

AI summary

Fixed validation bug that incorrectly rejected complex mathematical expressions such as sqrt(16) + pow(2, 3) and sin(3.14159/2) + cos(0).

Full changelog

Critical Fix for v0.3.1 Validation Issue

Problem Resolved

Version 0.3.1 introduced a validation bug that incorrectly rejected valid complex mathematical expressions:

sqrt(16) + pow(2, 3) was failing with validation error
sin(3.14159/2) + cos(0) was failing with validation error

Solution Implemented

Root Cause: Flawed parentheses counting in validation logic
Fix: Simplified validation to only catch empty function calls
Result: All complex expressions now work correctly

Verified Working

Core Functionality:

pow(2, 3) = 8.0 (original fix from 0.3.1)
sqrt(16) = 4.0
sqrt(16) + pow(2, 3) = 12.0 (now working!)
sin(3.14159/2) + cos(0) = 2.0 (now working!)

Enhanced Error Messages (preserved):

pow(2) -> Helpful error with example
sqrt() -> Clear parameter requirement message
Empty functions in complex expressions -> Specific guidance

Technical Details

Maintains all FastMCP 2.0 compliance
Preserves security measures and validation
Backward compatible with existing functionality
Function discovery resource (math://functions) working perfectly
